Lake George is located in northern New York, in the Southeastern corner of the Adirondack Park. The lake is used year round by local residents and tourists for many recreational activities, but the Class AA-Special rated lake is also still used as drinking water. Water quality in Lake George is threatened by various human activities including the introduction of aquatic invasive species into the lake through recreational boating and other related activities. To help protect the lake from the introduction and spread of invasive species that could negatively alter the lake’s ecosystem, shoreline property values, and the region’s tourism-driven economy, the Lake George Lake Steward Program was started in 2006. The main goal of the program is to prevent the introduction of invasive species into Lake George and to educate boaters about invasive species spread prevention. The lake stewards inspect boats at high traffic launches around the lake and collect quantitative data on the number of boats and last waterbody boats visited before entering Lake George. The stewards inspect all boats for plant and animal specimens, collecting anything that they find. Over the years the program has adapted to focus not just on boats launching, but also on boats leaving the lake. Data and specimens are collected from boats both launching and being retrieved from the lake. The data gathered will help to determine aquatic invasive species spread pathways between other regional waterways and Lake George.

Over the 2011 season, the Lake George lake stewards recorded 8593 boats. Boaters were asked what the last body of water their boat had been in during the past two weeks. The total number of waterbodies visited within two weeks of overland transport to Lake George was 193 unique waterbodies located in 15 different states. Lake George itself was the most common recorded previous waterbody visited with 2,853 boats; the next most frequent waterbody was the Hudson River at 100 boats. Boaters were most frequently coming from lakes in New York State (3,335). 1,016 (or 16.5%) boats were considered ‘at risk’ boats, meaning they had been in another body of water within 2 weeks prior to launching in Lake George. From all six launches lake stewards collected 171 aquatic organism samples from 125 boats and trailers, and identified 87 samples to be invasive species. Four different species were found: Eurasian watermilfoil, curly-leaf pondweed, water chestnut and zebra mussels. Approximately 85% of boaters reported having previously interacted with a lake steward. 75% of boaters reported taking spread prevention methods before arriving at a launch. Due to increased funding in 2011 compared to past years, there was an increase in the number of launches covered by stewards and the hours of daily coverage, resulting in a significant increase in the amount of invasive species spread prevention in 2011 than in previous years of the Lake George Lake Steward Program.

Introduction Started in 2006 by the Lake George Watershed Coalition Invasive Species Task Force, the Lake Steward Program entered its sixth year serving as a first line of defense against invasive species on Lake George. The Lake Steward Program aims to prevent the introduction of aquatic invasive species by providing education and outreach to boaters regarding spread prevention. The program strives to perform boat inspections on all vessels both entering and leaving Lake George at launches while stewards are on-duty and to gather quantitative data which can be used to determine pathways of spread between Lake George and other regional waterbodies.

Program Sponsors The Lake George Association (LGA): The LGA’s mission statement is “Working together to protect, conserve, and improve the beauty and quality of the Lake George Basin.” Since its inception in 1885, the LGA has evolved to incorporate and address the changing needs of the Lake George environment. The LGA advocates a reasoned, balanced approach to the management and conservation of the Lake George watershed through education, remediation, advocacy, and broad-based community involvement. The goal is to ensure the long-term stability of the lake’s exceptional water quality and the economic viability of the region. The Lake George Park Commission (LGPC): Authorized by New York State, the LGPC is responsible for overseeing and managing the unique resources of “the Lake George Park.” The Commission’s programs fill critical gaps to ensure the lake’s protection and encourage cooperation among the many public and private entities whose common goal is the lakes preservation. The Lake Champlain Basin Program (LCBP): The LCBP works in partnership with government agencies from New York, Vermont, and Quebec, private organizations, local communities, and individuals to coordinate and fund efforts which benefit the Lake Champlain Basin's water quality, fisheries, wetlands, wildlife, recreation, and cultural resources. The Lake George Watershed Coalition (LGWC): Formed in 1999, the LGWC is a coalition made up of the municipalities, counties, states agencies, and non-profit organizations involved in protecting Lake George. The purpose of the LGWC is to provide a forum to identify the priorities for protecting the lake’s water quality and to coordinate a proactive use of resources to accomplish this mission.

Lake George and its Watershed Lake George is located in northern New York, in the southeastern corner of the Adirondack Park. It is a 32 mile long, oligotrophic lake formed by earthquakes and glaciers. The lake is classified as Class AA-Special by New York State, which means one of its best usages is as a drinking water supply, and is used as such by many people around the lake.

The maximum depth of the lake is 196 feet, with an average depth of about 70 feet. The widest part of the lake is about 2 miles across, while the average width is 1.33 miles. There are over 170 islands dotting the lake’s surface. Lake George flows from the south to the north and drops 226 feet into Lake Champlain through the LaChute River in Ticonderoga.

Streams provide the lake with 55 percent of its water; the rest comes from precipitation directly on the lake’s surface and groundwater. There are 141 streams in the watershed, but 8 major streams providing about 2/3 of the total stream flow into the lake.

Invasive Species Background

An invasive species is any species that is not native to the ecosystem under consideration; and whose introduction does or is likely to cause economic or environmental harm or harm to human health. Invasive species are threatening ecological communities and impacting the economy nationwide. They are estimated to cost the United States more than $100 billion annually in environmental losses and damages. Invasive species are one of the greatest threats to biodiversity, second only to direct habitat loss in many locations. There are both terrestrial and aquatic invasive species that can disrupt land and water ecosystems. Within the waterbodies of the Adirondack Park, which includes part of the Lake Champlain Basin, invasive species are a top threat to biodiversity and water quality. Aquatic invasive species disrupt the aquatic food webs and habitats, out-competing native species and altering the ecological function of lakes and rivers.

Curly-leaf pondweed Eurasian watermilfoil Zebra mussels Asian clam

Currently, Lake George is known to have four invasive species: Eurasian watermilfoil (Myriophyllum spicatum), curly-leaf pondweed (Potamogeton crispus), zebra mussels (Dreissena polymorpha), and Asian clam (Corbicula fluminea). Although Lake George has only a handful of aquatic invasive species, nearby waterways are much more infested. Lake Champlain is documented as having 49 non-native species, the Saint Lawrence River 87, the Hudson River 91, and the Great Lakes with 186. All of these waterbodies are within close vicinity to Lake George and boats are easily trailered between them.

Program Description

The Lake George Lake Steward Program is an aquatic invasive species spread prevention and education program on Lake George. Lake stewards are hired to work at marinas and boat launches during the summer. Lake George has over 20 different marinas, various yacht clubs, public launches and many hotels that allow people to launch their boats. It is not possible for the lake stewards to cover all of the areas all of the time; therefore they strategically work at high traffic launches located around the lake. Lake stewards were stationed at 6 launches around the Lake during the summer of 2011. These locations included Mossy Point in Ticonderoga, Rogers Rock in Hague, Hague Town Launch in Hague, Norowal Marina in Bolton Landing, Dunham’s Bay in Lake George, and Million Dollar Beach in Lake George. Days and times of lake steward coverage differed by launch. The lake stewards helped stop aquatic invasive species introductions and spread awareness at these locations by educating boaters about the ecological threats of invasives and providing take home, outreach materials. Stewards helped stop the introduction and transport of invasive species via boats and trailers by visually inspecting boats and removing any plant or animal material found. Stewards also interviewed boaters to find out the last body of water the boat had visited during the two weeks prior to coming to Lake George and if they had taken any spread prevention steps before arriving to the launch. The Lake Steward Program is a crucial step in protecting the water quality of Lake George and preventing the spread of invasive species between waterbodies throughout New York and the Northeast.

Eight lake stewards were hired to work at six different high priority boat launch sites around Lake George. Prior to the initiation of the summer season, lake stewards attended trainings beginning on May 23rd to prepare them for their duties as a steward. They first participated in a region-wide training at Paul Smith’s College where representatives from the New York State Department of Environmental Conservation (NYSDEC), the Adirondack Park Invasive Plant Program (APIPP), the Adirondack Park Agency (APA), Paul Smith’s College, and the Lake Champlain Basin Program (LCBP) educated stewards on plant identification, interpretation techniques and data collection.

Lake stewards were stationed at their launches beginning on May 27th. Throughout the first weekend of duty, the stewards worked in pairs to become comfortable at the launches. There were additional trainings during the summer that the stewards attended to further their invasive species knowledge. In June, when the lake stewards were accustomed to their launch and duties, they attended an APIPP aquatic plant identification training at the Darrin Fresh Water Institute to gain more information about native and invasive species in or threatening Lake George and the Adirondack Park.

Quality Assurance Project Plan (QAPP)

In order to ensure that steward and greeter programs are coordinated in the Lake Champlain Basin, beginning in 2011, all Lake Champlain Basin Program (LCBP) grants issued that support steward programs require a QAPP that sets standards for the type of information that is collected and how it is collected, recorded and stored. A standard Quality Assurance Project Plan (QAPP) will ensure that survey information from the different steward programs in the basin is comparable. LCBP-funded steward programs will adhere to this QAPP by providing information specific to their program for review by LCBP staff.

The Lake George Lake Steward Program adhered to its guidelines and provided specific project information that was amended as a cover page to the QAPP and reviewed by the LCBP Project Officer before approval. Emily DeBolt, the program coordinator, was also the program QA officer. The lake stewards started working at boat launches around Lake George on May 27, 2011. However, the QAPP was not approved and signed by all necessary parties until June 9, 2011. So all data provided to the LCBP is from June 9, 2011 until the end of the program on October 10, 2011. Data collected prior to June 9, 2011 however is included in this report.

As required by the QAPP, this report provides a summary of results from the boat launch steward program surveys containing: the number of steward to boat-launch user interactions, the number of aquatic invasive species intercepted, and summary information on the vessel state of origin, last body of water visited, and possible AIS spread prevention measures taken by users. Additional data of interest was also collected in addition to the mandatory data collection points.

The data used in this report has been reviewed for logical consistency and coding errors as identified in appropriate standards. Any discrepancies between field survey forms and electronic data have been resolved and final datasets have been compared with original source information for consistency.

Number of Boats

Lake stewards recorded 8,593 boats during the 2011 season. Mossy Point had Launch Number of Boats 3,598 boats which was the greatest Dunham's Bay 512 number of boats out of the covered Hague Town 351 launches. Norowal Marina had the second Million Dollar Beach 109 most boats recorded with 2,227, then Rogers Rock with 1,796; followed by 512 Mossy Point 3598 at Dunham’s Bay, 351 at Hague Town Norowal Marina 2227 Launch, and 109 at Million Dollar Beach Rogers Rock 1796 (Table 1).

Some of the launches were busier than Total 8593 others, however the lake stewards spent Table 1: Summary of boats recorded at each launch during different amounts of time at different the summer and early fall season of 2011. launches. Therefore the total number of boats inspected is not necessarily an accurate measure of overall launch activity.

The stewards were stationed at launches from May 27th to October 10th. Lake stewards worked at Dunham’s Bay for 54 days during summer, 46 days at Hague Town Launch, 8 days at Million Dollar Beach, 116 days at Mossy Point, 69 days at Norowal Marina, and 80 days at Rogers Rock. Calculating the average number of boats inspected per day provides a more accurate representation of the boat traffic at various launches (Figure 1). Norowal Marina and Mossy Point had the busiest boat traffic averaging 32 and 31 boats per day. Million Dollar Beach was stewarded only eight days, but appeared to have more boat traffic than Dunham’s Bay Marina and Hague Town Launch which were stewarded over 45 days each.

Where are boats coming from?

Lake stewards asked boaters prior to launching where their boat had been in the last two weeks and the total response was 193 different waterbodies in 15 different states. Lake George itself was the most commonly visited waterbody with 2,853 visits within two weeks prior to launching. The Hudson River was the second most popular previous waterbody with 100 visits followed by Lake Champlain with 97 visits and Saratoga Lake in New York with 69 visits (Figure 2). Boaters most frequently had visited lakes in New York prior to launching in Lake George. 3,335 vessels had visited a waterbody in New York State within the past two weeks. Some of those boats had last been in Lake George. Some boat reported that they had not been in a waterbody in the past two weeks. Boaters also commonly visited waterbodies in New Jersey with 100 visits within the past two weeks. Stewards recorded 60 visits to lakes in Connecticut within two weeks prior to launching in Lake George (Figure 3). See Appendix A on page 80 for a complete list of previously visited waterbodies.

Number of samples removed from boats

After interacting with boaters, lake stewards would request to take a visual inspection of the trailer and boat for any plant or animal species. Boaters were encouraged to look along with the stewards so that they could learn how to inspect the boat themselves.

Lake stewards inspected 8,584 out of 8,593 boats being launched and retrieved from Lake George. 9 boats were not inspected over the course of the summer due to busy traffic. If a sample was found on a trailer or boat the stewards would remove it and put it in a sealed Ziploc bag with the boat registration number, date, and location written on the front. Samples were then identified by LGA staff. Sample bags could contain more than one plant or animal species which resulted in a different number of samples than number of boats found with plant and animal material.

Between all six of the launches, a total of 171 samples were removed from 125 trailers or boats before entering or after leaving Lake George (Table 2). Out of the 171 samples, 87 were found to be an invasive species, making 51% of all samples removed invasive (Table 3).

Invasive Species Found There were four different species of invasives identified out of the 87 samples: Eurasian watermilfoil, curly-leaf pondweed, water chestnut, and zebra mussels. Samples were taken from boats going in and out of Lake George. There were 37 invasive species samples taken from boats launching into Lake George: 22 Eurasian watermilfoil, 9 curly-leaf pondweed, 4 water chestnut, and 2 zebra mussels (Figure 4). Stewards removed 50 samples of invasive species from boats leaving Lake George: 42 Eurasian watermilfoil, 6 curly-leaf pondweed, and 2 water chestnut (Figure 5). Rogers Rock stewards removed the largest number of samples containing invasive species from boats before they were launched, and Hague’s steward removed the most invasive species from boats being retrieved from the lake.

Invasive Organism on Departing Watercraft Information Form

Lake stewards were provided with an additional form to gather additional information about invasive species coming out of Lake George. Lake George is known to have 4 invasive species: Eurasian watermilfoil, curly-leaf pondweed, Asian clam, and zebra mussels. However, there were two occurrences in which a lake steward removed water chestnut from boats coming out of Lake George. The departing watercraft form helped to determine if the boater came in contact with that invasive species in Lake George. Information gathered for the form included: where on the boat/trailer the organism was found, description of the specimen, where in the lake the boat was driven, where the boater thought they could have come in contact with the organism, whether the boater had noticed any plant or weed beds in the Lake, whether the boater noticed any organism before they launched, and where the boat had been in the past two weeks.

For both occurrences of water chestnut being removed upon boat retrieval, the lake steward found a water chestnut nutlet attached to the trailer and not the boat itself. A lake steward was not present when either of the boats launched so it is likely that the water chestnut was not encountered in Lake George but was brought from a previous waterbody.

Above: Location on trailers where water chestnut nutlets were found.

Possible Sources of Invasive Species Introductions into Lake George

The lake steward program addresses the overland transport pathway of aquatic invasive species. Possible sources of invasive species are the waterbodies trailered boats come from within the prior two weeks of launching in Lake George. Due to inconsistencies in collecting and recording the last waterbody visited in the past two weeks for boats being retrieved from Lake George, the possible sources listed in this report are only for invasive species removed from boats launching into Lake George. The waterbodies are only possible sources because the invasive species found may not be present in that waterbody and had attached to the boat in a previous waterbody. However, by examining the Possible sources of Eurasian watermilfoil possible sources of the invasive species removed 2011 from boats that were 10 about to be launched in 8 Lake George, it can be 6 10 estimated where the 4 5 2 1 2 1 2 1 possible invasive species 0 “hot spots” are.

At Risk Boats

At risk boats are those that have been in a body of water within two weeks prior to their lake steward interaction at Lake George. The two week time is chosen by generalizing the amount of time that aquatic invasive species can live out of water. Some species can live out of water longer than two weeks.

Of all the launched boats inspected, one percent of boats were found with invasive species samples. However, 73% of the boats inspected were in a waterbody within two weeks prior to launching in Lake George and had potential to spread invasive species. A total of 1,016 boats, or 16.5%, had been in a body of water other than Lake George within those prior two weeks thus having the potential to introduce new invasive species that Lake George does not currently have.

The lake stewards were able to collect additional information while at the launches working on invasive species spread prevention.

Vessel Types Motorboats made up at least 74% of all vessels at all launches during 2011 (Figure 10). Rogers Rock had the largest variety of boats recorded in terms of motorboats, sailboats, personal water crafts (PWCs), canoes, and kayaks. Sailboats were launched the least at all six of the launches during 2011.

Lake George Park Commission (LGPC) Boat Registration

The Lake George Park Commission requires that on Lake George all vessels 18 feet or longer, or any vessel mechanically propelled by a motor 10 h.p. or greater, must be registered and display a LGPC registration decal. Lake stewards recorded whether or not vessels required to have a registration decal according to the LGPC parameters were in compliance. However, they did not enforce the regulation nor report individuals who were not in compliance.

Compliance was at least 89% at all six launches during 2011( Figure 11). The percentages of boat registrations varied between launches, yet two launches, Norowal Marina and Dunham’s Bay Marina, had 100% compliance. The managers at Norowal Marina ensured 100% compliance by informing boaters at the launch to be aware of the requirement and selling boat registrations at the marina. At the other lake steward launches, including Dunham’s Bay, boaters do not have the opportunity to register their boat, therefore they would have to register it prior to arriving at the launch.

Group Size Lake Stewards recorded the number of people using the water vessel that was inspected. This number can also be used to estimate how many people the lake stewards interacted with at the boat launches. Group sizes ranged from 1 to 14 people. In total, the lake stewards interacted with 19,882 people at all six launches during 2011.

Previous Lake Steward Interaction Lake stewards ask boaters whether or not they have previously interacted with a lake steward. This allows the steward to adjust their interpretive message to address the information that can be best utilized by the boater. Previous lake steward interaction differed by launch between 70-97%, with an 85% overall average during 2011 (Figure 12).

Prevention Step Figure 14: Summary of spread prevention steps taken reported by boaters.

From May 27th to October 10th of 2011, lake stewards interacted with 8,583 boats. Recreational boats and their trailers are possible vectors for transporting aquatic invasive species. A total of 193 waterbodies spanning 15 states were visited by boaters coming to Lake George during the 2011 field season. With four more stewards working during the season, and two additional launches covered, the number of boats inspected tripled last year’s total of 2,538. Multiple stewards per launch allowed the coverage to last longer each day which increased the number of boats that were inspected and allowed more samples to be taken, which lead to an improvement in invasive species protection for Lake George.

Based on the data collected, it appears that the three waterbodies that pose the largest threat to Lake George are the Hudson River, Lake Champlain, and Lake Hopatcong in New Jersey. The Hudson River and Lake Champlain had the greatest boat counts coming to Lake George, and also have large numbers of invasive species. A sample of water chestnut, an invasive Lake George does not have, was found on boat that was previously in the Hudson River. If the lake steward had not inspected the boat, there could have been a new introduction of this invasive species into the lake. Lake Champlain is a constant invasive species threat because of its close proximity to Lake George and the high number of boaters who launch in Lake Champlain and Lake George within a two week period. Five different trailers and boats, out of 55, that were previously in Lake Hopatcong, New Jersey had the potential to spread Eurasian watermilfoil in Lake George if samples had not been removed by lake stewards. Lake Hopatcong should continue to be a waterbody to look out for because it is also known to have curly-leaf pondweed and water chestnut.

Although only one percent of boats were found to have an invasive species sample, 16.5% of boats that launched were in another waterbody other than Lake George two weeks prior to Lake George. These boats have the potential to introduce new invasive species to the lake. 125 boats had samples removed before entering or when leaving Lake George from all six launches. Of the 125 boats, 171 samples were removed and 87 were found to be an invasive species making 51% of all samples removed invasive. Four different species of invasives were identified out of the samples: Eurasian watermilfoil, curly-leaf pondweed, water chestnut, and zebra mussels.

Continuing this education and spread prevention program is critical to protecting Lake George from invasive species. Prevention is the most cost-effective approach to fighting invasive species. Once invasives have established in a lake, eradication is unlikely and costly.

Introduction

Dunham’s Bay is a privately owned launch located on the southeast portion of Lake George. This was the third season that there was a lake steward at this launch location. There was a steward here in 2008 and 2009, however not in 2010 due to limited program funding. This area is predominantly wetlands with a narrow channel that connects the launch to the main part of Lake George. In order to access the lake from the launch boaters must go under a low bridge, limiting the use of this launch to smaller boats. Also due to the location, boaters launching in Dunham’s Bay are often heading out to one of the many campsites on Lake George, requiring the steward to be prepared to address other environmental issues, such as forest pests and firewood. Since the Dunham’s Bay Marina area has a large amount of native aquatic vegetation in the wetland, it was essential to have a lake steward present to prevent both the introduction and spread of invasive species.

Materials and Methods

In May, the Lake George Association prepared their stewards by participating in a training session at Paul Smith’s College. This orientation included members from the Adirondack Park Agency, Adirondack Invasive Plant Program, Darrin Fresh Water Institute and the NYS Department of Environmental Conservation. Following an additional training at the LGA. The lake steward was stationed at Dunham’s Bay from May 27th to September 3rd. A lake steward was present at Dunham’s Bay Marina on Monday through Thursday from 8 to 4:30 pm. The lake steward had a table of brochures and informational handouts and carried bags for the collection and labeling of samples along with a cooler for sample storage. The steward interacted with boaters and collected data from each vessel, which included the time of launch or retrieval, boat type, horsepower and stroke on outboard engines, group size, previous Lake Steward interaction, presence of the LGPC decal and the registration of the vessel. The boaters were asked where the boat was last used in the past two weeks. The lake steward would then ask if the boater had taken any preventative measures against the spread of invasive species. Lastly, a thorough inspection was conducted by the steward to detect the presence of invasive species on the vessel. If any organism was found, it would be bagged, labeled immediately and put into a cooler for storage. All data collected was transferred from a handwritten spreadsheet to Microsoft Excel for further analysis.

Results

Number of Boats

The lake steward was stationed at Dunham’s Bay during the week from Monday to Thursday for eight hours at a time, for 15 weeks. The marina had their own attendant working on the launch on the weekends. Some weekend days were covered occasionally by the lake steward as well. During the 15 weeks of lake steward duty the week of 7/3-7/9 was the busiest by far with 102 boats recorded (Figure 15). The total number of boats inspected at Dunham’s Bay during the 15 week period was 512. 407 boats were recorded launching and 105 were recorded retrieving. In terms of weekday activity, Mondays appear to be more popular than other days. The average number of boats per day was 8. Saturday had the greatest average of boats by day of the week with 20 boats (Figure 16). This data can help determine priority days of the week and times of the season for lake steward coverage in the future.

The Lake George Park Commission requires that on Lake George all vessels 18 feet or longer, or any vessel mechanically propelled by a motor 10 h.p. or greater, must be registered and display a LGPC registration decal. Lake stewards recorded whether or not vessels required to have a registration decal according to the LGPC parameters were in compliance, but did not enforce the regulation or report individuals who were not in compliance.

Boaters launching at Dunham’s Bay had 100% compliance with boat registration decals. The launch does not sell registration decals, therefore boaters must have purchased the registration before arriving at the launch. Previous Lake Steward Interaction

Previous waterbodies Lake stewards recorded what waterbodies launching boats had been in within two weeks prior to launching in Lake George. 328 boats had been in a waterbody within two weeks prior to launching at Dunham’s Bay. Some of those boats had last been in Lake George. Excluding Lake George itself, there were 40 different waterbodies boats had been in (Table 4). Lake George had the greatest frequency for a previous visited waterbody with 250 boats, followed by Saratoga Lake, NY with 10 boats (Figure 19).

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 407 boats launched at Dunham’s Bay, 78 or 19% can be considered at risk boats.

Plants and Animals Found

One major part of a lake steward’s job is to prevent the spread of invasive species by visually inspecting all boats before and after launching. Stewards often performed inspections with boaters to teach them how and what to look for on their own in the future. There are common locations on trailers and boats to look for hitchhiking invasive species including the hitch, live well, rollers, axle, and propeller.

At Dunham’s Bay, 14 samples were removed from 9 boats. Three out of the fourteen samples were identified as an invasive species (Table 5). There was one sample each of Eurasian watermilfoil, curly-leaf pondweed, and water chestnut found. Six of the nine boats found with samples were coming out of Lake George which is not surprising due to Dunham’s Bay wetland environment.

Spread Prevention

When lake stewards interact with boaters, one of the questions asked Boaters that Took Spread Prevention Measures is whether or not the boater took Dunham's Bay 2011 any measures to prevent the spread of aquatic invasive species prior to launching. Spread prevention No, 103, 20% measures include, but aren’t limited to: a dried boat, visual inspection, Yes, 409, 80% washed boat, drained bilge, and disposed all bait. There were 409 boaters, or 80%, who reported taking one or more spread prevention measures before launching (Figure 21). The most common prevention step reported Figure 21: Percent of boaters that reported taking spread was washing the boat (Figure 22). prevention measures at Dunham’s Bay.

Summary

Compared to the other five launches Dunham’s Bay should be considered a moderate priority launch based on the number of boats launching. However, many smaller boats utilize this site because of its location and access limitation making it a more economic launch. Smaller boats are often trailered greater distances, making this launch a priority location for possible new invasive species introductions from further away. The week of Fourth of July was the busiest at Dunham’s Bay, and the week after had the greatest count of boaters who had previously interacted with a lake steward, suggesting that the launch has a pretty steady repeat customer base at that time of the year.

Hague, NY

Introduction

The Hague Town Launch is part of the Robert E. Henry Memorial Park which includes a public beach, visitor center, playground, and boat slip with public docking. The parking lot, launch, and boat slip are managed by a park attendant who removes plant life and debris from the launch area and ensures visitors' compliance with the park ordinances. The launch is owned and operated by the Town of Hague and a $10 fee is required for all non-residents of Hague to launch.

Materials and Methods

A lake steward was stationed at Hague Town Launch on Wednesdays through Sundays until the end of June. From July until August 12th, the steward acted as both the park attendant and lake steward in a 10 days on/ 4 days off rotation. The steward set up a table with information regarding invasive species and boating safety and rules . After a brief introduction the steward would perform an inspection of the boat to see if any plants or other organisms were attached. If a sample was found, it was bagged and identified. The steward would interact with all boaters and assist in boat launching as well as collect data such as time of arrival, launch or retrieval, engine type and horsepower, previously visited waterbodies, spread prevention practices and group size. Boaters with no previous knowledge of invasive species were encouraged to investigate the informational cards and brochures provided on the steward's table. Since Eurasian watermilfoil and curly-leaf pondweed are found growing in the water at the Hague Town launch, many boats and trailers departing the lake were sprayed down with a hose provided by the Town of Hague to remove the visible bits of plant material.

Results

Number of boats

A total of 351 boats were recorded by the lake steward at the Hague town launch. 262 boats were recorded launching and 89 were recorded retrieving. The busiest week recorded at Hague Town Launch was 7/17-7/23 with a total of 60 boats (Figure 23). The next busiest week was 5/29-6/4 with 55 boats recorded.

Previous Lake Steward Interaction

After a lake steward introduces themselves to the boater they ask if the boater has had a previous interaction with a lake steward. This allows the lake steward to adjust their interpretive message to address the information that can be best utilized by the boater.

The Hague Town Launch steward recorded that 88% of boaters said they had a previous interaction with a lake steward. Hague had the second greatest percentage of boaters who reported having already interacted with a lake steward out of the other five launches. The week of 6/12-6/18 had the fewest number of boaters, 29 or 78%, who reported previous interaction with a lake steward. There were three weeks where 100% of boaters that launched at Hague reported that they had interacted with a lake steward before, the weeks of 6/19-6/25, 7/31-8/6, and 8/7-8/13 (Figure 27).

Lake stewards recorded what waterbody launching boats had been in within two weeks prior to launching in Lake George. Within two weeks prior to launching at the Hague Town Launch, 59 boats had been in another waterbody (Table 6). Excluding Lake George, 18 boats had been in 11 different waterbodies spanning over three states: New York, New Jersey, and Connecticut (Figure 28). Lake George had the greatest number of visits for a previous waterbody with 41. Long Island Sound and Schroon Lake were the next frequently visited waterbodies with 3 visits each (Figure 29).

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 262 boats launched at Hague Town Launch, 18 or 7% can be considered at risk boats.

Plants and Animals Found

The Hague Town Launch lake steward visually inspected all boats that were launching and retrieving. There were 51 samples removed from 45 boats during the lake steward’s visual inspection. Five boats had samples removed prior to launching and 40 boats had samples removed when retrieving. All 45 boats were carrying at least one invasive species. There were 44 identified samples of Eurasian watermilfoil and 6 samples of curly-leaf pondweed (Table 7).

Spread Prevention

The lake steward asked boaters whether or not they have taken any measures to prevent the spread of aquatic invasive species prior to launching at the Hague Town Launch.

Out of 351 boats recorded, 237 of those boaters reported taking spread prevention measures (Figure 30). The 68% percent of boaters who reported having done so is slightly below the average number of boaters who said yes for all six launches combined at Figure 30: Percent of boaters that reported taking spread prevention measures at Hague Town Launch. 75%.

Washing the boat before launching proved to be the most common spread prevention method boaters took with 218 boats recorded (Figure 31). Zero boaters were recorded having dried their boat, or disposed of bait as a spread prevention method.

Figure 31: Summary of reported prevention steps taken by boaters at Hague Town Launch

The lake steward at the Hague Town Launch inspected 351 boats during the 2011 season. Eighteen boats were in other within waterbodies other than Lake George two weeks prior to launching. The steward collected a total of 50 invasive species samples from trailers and boats at this launch.

There was not a large amount of diversity in where the boats were coming from, and not many samples of invasive species found prior to launching, however the Hague Town Launch should be considered high priority. All samples taken from boats coming out of Lake George contained invasive species. If these samples were not taken off, these boats could spread invasive species to other nearby lakes, or even to different areas on Lake George that may not have these invasive species yet.

Million Dollar Beach Lake George, NY

Introduction

Operated by the NYS DEC, the launch at Million Dollar Beach is open only after Labor Day and before Memorial Day. The launch is closed during the summer for swimming season as Million Dollar Beach is the largest and most well-known beach in Lake George, offering lifeguards, showers, picnic areas and plenty of room to swim. This was the first season of a lake steward at this location. The steward was there for a few days at the end of the season to gather some data to help increase our understanding of the users at this launch location.

Materials/ Methods

The lake steward at Million Dollar beach attended training sessions led by staff from LGA, APIPP, Paul Smith’s College, APA, and NYSDEC that extensively educated them on both terrestrial and aquatic invasive species. The lake steward received a binder from the LGA containing further information concerning plant identification and invasive species to better educate them and provide interpretation for the general public. The lake steward was also given brochures, pamphlets, stickers, and both visual and physical examples of invasive species within the Adirondack Park. All of this information was displayed on a table that the lake steward was stationed at throughout the summer. The lake steward could be identified by their blue “Lake Steward” t-shirt and nametag as they carried out their responsibilities of inspecting vessels and collecting quantitative data on boats entering and leaving Lake George. This data included the time, if the vessel was a launch or retrieval, horsepower/stroke, group size, presence of a LGPC decal and previous steward interaction. The boater was also asked if they had taken any prevention steps against the spread of invasive species and the last body of water their boat had been in the last two weeks. If any boats were found to be carrying aquatic hitchhikers, the sample was promptly removed, recorded, bagged and identified by the steward. All of this information was collected on spread sheets to further analyze.

Results

Number of Boats

A lake steward worked at Million Dollar Beach Launch for a total of 8 days from September 9th to October 1st. A total of 109 boats were recorded with 92 boats launching and 17 retrieving. The busiest of the four weeks the steward was stationed at Million Dollar Beach was 9/11- 9/17 with 52 boats recorded (Figure 32).

The lake steward worked primarily on Fridays, Saturdays, and Sundays (Figure 33). On average, the lake steward inspected 15 boats per day. Sundays were the busiest day on duty with 44 boats recorded during two days of working. Total Boats by Week Million Dollar Beach 2011 60 50 40 30 20

Previous Waterbodies

Lake stewards recorded which waterbody launched boats had been in within two weeks prior to launching in Lake George. There were 68 boats that had been in a waterbody within two weeks prior to launching in Lake George (Table 8). Excluding boats previously in Lake George, 32 boats had previously been in 16 other waterbodies. These 32 boats are a risk for carrying invasive species that Lake George does not currently have.

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 92 boats launched at Million Dollar Beach, 32 or 35% can be considered at risk boats.

Plants and Animals Found

There were zero samples taken from all 109 inspected boats during the time the steward was stationed at the Million Dollar Beach Launch, and no invasive species found. Spread Prevention

The lake steward asked boaters if they took any measures to prevent the spread of aquatic invasive species prior to launching at the Million Dollar Beach Launch. Spread prevention measures include, but aren’t limited to a dried boat, visual inspection, washed boat, drained bilge, and disposed all bait.

There were 86 boaters, or 79% that stated they took spread prevention measures prior to launching (Figure 39). Washing the boat before launching was the most commonly reported spread prevention step taken by boaters at Million Dollar Beach. The second and third most frequent reported measures taken were visually inspecting the boat, and drying the boat (Figure 40). Figure 39: Percentage of boaters that reported taking spread prevention measures prior to launching at Million Dollar Beach.

Figure 40: Summary of reported prevention steps taken by boaters at Million Dollar Beach in 2011. Summary

Although a lake steward was only stationed at Million Dollar Beach a total of eight days, the steward inspected 109 boats, which averaged 13 boats per day. The launch is only open for a short period of time, but from the initial findings of the volume of boaters using the launch and where the boats seem to be coming from, it appears that increased steward at this location in the future is warranted.

Introduction

Mossy Point boat launch is a free, 24 hour state-owned public launch in the town of Ticonderoga. The New York State Department of Environmental Conservation manages and maintains this launch including its pump out station, public restrooms and a free parking lot. Located on the northern most point of Lake George, the Mossy Point launch is extremely close to Lake Champlain and allows for easy transportation from one lake to the other. This launch is considered to be a high priority launch because of the amount of boater usage and risk of invasive species transportation from nearby waters. It was the lake steward’s job to examine all vessels to prevent the spread of invasive species.

Materials and Methods

Stewards attended training at both Paul Smith’s College and the Lake George Association, which included presentations by a number of environmental organizations in the Adirondacks and extensive training on how to identify both native and invasive plants. Stewards were also taught how to interact with and provide interpretation to boaters and were given a chance to practice their new skills on each other. After the training period, the lake stewards were ready to educate the public. A tent and table with educational material on Lake George and invasive species was set up each day. A sign notified the boater to stop before launching and allow the steward to speak with them for a few minutes regarding their role in invasive species spread prevention. The steward would greet the boater and inquire about the boater’s previous steward interaction and would then proceed to explain their goal and provide them with general information on invasive species and their spread. The boater would then be asked to provide information on the last body of water visited within the past two weeks. The steward would proceed to conduct a careful inspection and evaluation of the trailer and boat, collecting data on the engine type, horsepower and stroke, registration number, presence of a LGPC decal and group size. If an organism was found, it would be removed and placed in a water- filled Ziploc bag and labeled. The written data would then be entered into Microsoft Excel to be analyzed further.

Number of Boats

Three lake stewards were stationed at Mossy Point from May 27th to the end of August, seven days a week from 8 am to 8pm. One steward was stationed at the launch in September and October 4 days a week from 8 am to 4:30 pm. During the 116 days a lake steward was present at Mossy Point, a total of 3,598 boats were recorded. 2480 boats were recorded launching and 1118 were retrieving. Mossy Point had the greatest number of recorded boats out of all six launches.

Over the 21 weeks the lake stewards worked at Mossy Point, the week of 6/26-7/2 was the busiest with boat traffic, inspecting 318 boats (Figure 41). July was the busiest month at Mossy Point, making up the majority of the boats inspected with 1,422 boats.

Lake George Park Commission Decal

The Lake George Park Commission (LGPC) requires that on Lake George all vessels 18 feet or longer, or any vessel mechanically propelled by a motor 10 h.p. or greater, must be registered and display a LGPC registration decal. Lake stewards recorded whether or not vessels required to have a registration decal according to the LGPC parameters were in compliance. However, they did not enforce the regulation or report individuals who were not in compliance.

During the 21 weeks of stewardship at the Mossy Point Launch, there were five weeks recorded that had 100% compliance with the LGPC decal requirement. The overall percent compliance comparably to the other launches was 97% (Figure 44).

Previous Lake Steward Interaction

After a lake steward introduced themselves to the boater they asked if the boater had a previous interaction with a lake steward. This allowed the lake steward to adjust their interpretive message to address the information that could be best utilized by the boater.

Mossy Point launch had the greatest average of boaters who reported having previously interacted with a lake Figure 45: Percent of boaters that had reported having a previous lake steward steward out of all the interaction before launching at Mossy Point. launches. Ninety-seven percent, 3,492 boaters, at Mossy Point said they had previously interacted with a lake steward. The percent yes, stayed consistent week by week only differing by three percent at the most (Figure 45). The only week that was abnormal was the first week the stewards worked the launch, 5/22-5/28.

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 2480 boats launched at Mossy Point, 295 or 12% can be considered at risk boats.

Plants and Organisms Found

The Mossy Point lake stewards visually inspected all boats that were launched and retrieved from Lake George for any organisms attached.

Eleven boats had 11 samples taken from them by a lake steward, with only one sample identified as an invasive species. Curly-leaf pondweed was the invasive species that was identified (Table 10). Five of the samples are unknown because they were not bagged and sent for identification. Samples for Mossy Point are lower than expected. This anomaly in the data is due to logistical issues of sample collection and transport from this launch site and should not be attributed to an actual lower number of samples at this site compared to other sites. Results are still reported, but should not be used to draw conclusions from.

Spread Prevention Methods

The lake steward asked boaters if they had taken any measures to prevent the spread of aquatic invasive species prior to launching at the Mossy Point Launch. Spread prevention measures include, but aren’t limited to a dried boat, visual inspection, washed boat, drained bilge, and disposed all bait.

Lake stewards reported 2,728 boaters, or 76%, who said they took one or more spread prevention steps before launching (Figure 48). Of the 2,728 boaters, 2,557 reported washing their boat prior to launching (Figure 49).

Summary

Mossy Point is one of the main launches at the northern end of Lake George and continued to have a large numbers of boat traffic, with a calculated total of 3,598 boats for the season. The launch had the highest frequency of boaters who had interacted with a lake steward before. The appearance of boats being cleaner at this launch compared to other launches is unfortunately due to logistical issues that were experienced with sample collection and data entry from this site, and should not be attributed to boats actually being cleaner. We plan on correcting this issue for the next season. The leading risk at the Mossy Point launch is the introduction of new aquatic invasive species mainly due to its close proximity to Lake Champlain, which has over 10 times the number of invasive species as Lake George.

Introduction

With excellent proximity to island camping in the Narrows and the Mother bunch as well as easy access to many motels and the Southern Basin, Norowal Marina is an ideal launching point for visitors. Due to its location, Norowal experiences high traffic, warranting constant lake steward presence. The lake steward’s primary job was to inspect all launching and retrieving boats for any aquatic hitchhikers. They also educated boaters about invasive species and advised them about future prevention methods and clean boating practices. Any aquatic life found was collected and recorded for further analysis. A key line of defense against aquatic invasive species, the lake stewards provided 12 hour coverage Wednesday through Sunday from June 23rd to August 25th and 8 hour coverage from May 27th– June 23rd.

Materials and Methods

Before their arrival at Norowal Marina, both the lake stewards attended training sessions led by staff from LGA, APIPP, Paul Smith’s College, APA, and NYSDEC that extensively educated them on both terrestrial and aquatic invasive species. The lake steward received a binder from the LGA containing further information concerning plant identification and invasive species to better educate them and provide interpretation for the general public. The lake steward was also given brochures, pamphlets, stickers, and both visual and physical examples of invasive species within the Adirondack Park. All of this information was displayed on a table that the lake steward was stationed at throughout the summer. The lake steward could be identified by their blue “Lake Steward” t- shirt and nametag as they carried out their responsibilities of inspecting vessels and collecting quantitative data on boats entering and leaving Lake George. This data included the time, if the vessel was a launch or retrieval, horsepower/stroke, group size, presence of a LGPC decal and previous steward interaction. The boater was also asked if they had taken any prevention steps against the spread of invasive species and the last body of water their boat had been in the last two weeks. If any boats were found to be carrying aquatic hitchhikers, the sample was promptly removed, recorded, bagged and identified by the steward.

The greatest percentage of boaters that said they had a previous lake steward interaction was 82% during the week of 7/3-7/9, equaling 248 boaters (Figure 53).

Previous Waterbodies

Lake stewards recorded what waterbody launching boats had been in within two weeks prior to the visit to Lake George. Some boats may have not been in any waterbody in the past two weeks. Boats had previously been in 113 different waterbodies prior to launching at Norowal Marina (Table 10). Lake George had the largest number of prior visits with 338, Lake Hopatcong, NJ was the second most frequented waterbody with 44 visits (Figure 54). Twenty- six percent of launching boats were in a waterbody within 2 weeks prior to launching at Norowal Marina and can be considered at risk boats due to the potential to spread invasive species.

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 1763 boats launched at Norowal Marina, 453 or 26% can be considered at risk boats.

Plants and Animals Found

The Norowal Marina stewards visually inspected all boats that were launched and retrieved from Lake George. If any samples were found, they were removed from the boat and identified. Norowal Marina stewards removed 42 samples from 24 boats (Table 11). Of those samples, 13 were identified as invasive species. Invasive species samples included Eurasian watermilfoil, curly-leaf pondweed, zebra mussels, and water chestnut. Ten boats were found with 11 samples of invasive species prior to launching: 8 Eurasian watermilfoil, 2 curly-leaf pondweed, and 1 zebra mussel. Two boats came out of Lake George with 2 invasive species samples as well: 1 Eurasian watermilfoil and 1 water chestnut. Lake George is not known to have water chestnut so the lake steward filled out an Invasive Organism on Departing Watercraft Information Form in order to gather more information about the sample. Information gathered on the form helped to determine whether or not the boater had picked up the invasive species in Lake George. The water chestnut nutlet was found on the trailer and had previously been in the Mohawk River which is known to have water chestnut. Also, the boater did not encounter a lake steward when the boat was launching so it is likely that the boat was not inspected prior to launching. From this, it is likely that the water chestnut was not picked up in Lake George but was brought from a previous waterbody.

Spread Prevention

The lake steward asked boaters whether or not they took any measures to prevent the spread of aquatic invasive species prior to launching at Norowal Marina. Spread prevention methods include, but aren’t limited to a dried boat, visual inspection, washed boat, drained bilge, and disposing of all bait.

Lake stewards at Norowal Marina recorded 1,598, or 72% of boaters that reported taking one or more spread Figure 56: Percent of boaters that took spread prevention prevention steps before launching their measures before launching at Norowal Marina in 2011. boat (Figure 56).

Washing the boat seemed to be the most popular spread prevention method reported to have been taken, with 1,115 boaters saying they had done so. Inspecting, drying, draining the bilge, draining bait bucket, and draining livewell were the other methods boaters reported taking (Figure 57).

Figure 57: Summary of reported prevention steps taken by boaters at Norowal Marina in 2011. Summary

With an average of 32 boats per day, Norowal Marina continues to be a high priority launch. Inspecting over 2,225 boats, lake stewards collected 42 samples. Thirteen samples were identified as an invasive species, 11 of them found on boats prior to launching. Lake stewards prevented eight Eurasian watermilfoil samples, 2 curly-leaf pondweed samples, and 1 zebra mussel sample from entering the lake and possibly spreading.

Introduction

Rogers Rock is a very popular campground for vacationers. Owned and operated by the NYSDEC, Rogers Rock is the second largest campground in New York. During its annual operating season, the campground sees thousands of visitors, some that come from long distances to enjoy the beauty of Lake George. Many of these visitors bring their boats from a wide variety of waterbodies, both causing Rogers Rock to be a high volume launch site and justifying the need for a lake steward to be stationed at this launch.

Materials and Methods

The steward was present to inspect boats and provide interpretation and education to the public at Rogers Rock from May 27th to August 25th seven days per week from 8 am to 4:30 pm. Methods used at Rogers Rock were similar to those used by lake stewards at other boat launches on Lake George. The steward would approach the boater, introduce his self as a lake steward and ask to perform a boat inspection. During this inspection, the boat owner was informed about possible negative ecological and economic impacts associated with the introduction of invasive species. Boat owners were also asked if they took any preventative steps to stop the spread of invasive species. If prevention steps were lacking, suggestions were made to help them stop the spread in the future. Boaters were also asked to provide the last body of water they were in within the past two weeks. Visual data such as inboard/outboard, horsepower, group size, time, and the presence of a LGPC decal were taken. At the end of each boat inspection, boaters were given a card and sticker encouraging boat inspection after every time they launched or retrieved their boat. If plants/ animals were found on the vessel, there were removed, bagged, and identified.

Results

Number of Boats

From May 27th to August 25th, the lake stewards at Rogers Rock recorded data for 1,796 boats. 1147 boats were recorded launching and 649 were retrieving. The number of boats per week ranged from a minimum of 31 to a maximum of 259. The largest frequency of boats was seen during week of 7/31-8/6 (Figure 58). The week of and after the Fourth of July holiday had large boat counts with over 200 inspected boats each week.

With almost an equal number of weekdays worked, it is accurate to say that Saturday was by far the busiest day at the Rogers Rock launch. There were 503 boats out of 1,796 that were inspected on a Saturday, the next busiest day being Sunday with a total of 317 boats inspected (Figure 59).

Previous Waterbodies

A total of 52 different waterbodies were visited by launching boats at Rogers Rock within two weeks prior to launching (Table 12). Lake George was the most common previously visited waterbody accounting for 552 boats at the launch. The Hudson River, 19 visits, and Brant Lake, 13 visits, were the next two most common previously visited waterbodies by boaters (Figure 63). Twelve percent of the boats had been in another waterbody two weeks prior to launching at Rogers Rock.

At Risk Boats At risk boats are those that have been in a body of water other than Lake George within 2 weeks prior to launching. These boats are considered at risk for transporting invasive species since 2 weeks is the generalized amount of time that aquatic invasive species can live out of water. Of the 1147boats launched at Rogers Rock, 140 or 12% can be considered at risk boats.

Plants and Animals Found

All boats launching or retrieving at Rogers Roger while there was a lake steward working were visually inspected for plant and animal invasive species. Every sample that was found, whether invasive or native was removed and bagged. Out of the 1,795 boats that were inspected, 36 boats had 53 samples removed, including 20 samples of invasive species (Table 13). Nine samples of Eurasian watermilfoil, 5 of curly-leaf pondweed, 3 of water chestnut, and 1 of zebra mussels were removed from boats prior to launching. The zebra mussel sample found was the only one found out of the launches that had been in a waterbody, Cayuga Lake, NY, two weeks prior to launching in Lake George and is known to have zebra mussels. One sample of Eurasian watermilfoil and 1 of water chestnut were found on boats retrieving from Lake George. Lake George is not known to have water chestnut so the lake steward completed a Organism on Departing Watercraft Information Form to help determine if the boat came into contact with the invasive species in Lake George. The sample was a water chestnut nutlet that was attached to the rug on the trailer. The boat had not encountered a lake steward prior to launching so it is possibly that the boat was not inspected and the water chestnut nutlet was from a previous waterbody.

Spread Prevention

The lake steward asked boaters if they took any measures to prevent the spread of aquatic invasive species prior to launching at Rogers Rock. Spread prevention method include, but aren’t limited to a dried boat, visual inspection, washed boat, drained bilge, and disposed all bait. A total of 1,395 or 78% of the boaters responded that they had taken some kind of spread prevention measures Figure 65: Percent of boaters that reported taking spread prior to launching (Figure 65). prevention measures before launching at Rogers Rock in 2011. Washing the boat before launching was the most popular spread prevention measure 1,307 boaters reported taking (Figure 66). No boaters reported draining their bait buckets as a prevention measure.

Summary

The lake stewards at Rogers Rock Campground had a busy summer at the launch inspecting a total of 1,796 boats. More coverage and longer hours aided in the increase number of boats inspected at Rogers Rock which tripled since the 2010 season. The average boats seen per day at Rogers Rock have increased an additional 10 from last season.

Being a state owned campground, Rogers Rock has the potential to see many different types of invasive species being carried to Lake George by outside visitors. Stewards have the opportunity to educate boaters about the invasive species they may be carrying on their boats, but also about the invasive pests they may have transported to their campsite. Rogers Rock was the only launch to see an at risk sample of zebra mussels, and stewards prevented 18 samples of invasive species from entering the waters of Lake George.

During the 2011 season, lake stewards worked beyond their duties at the launches to help educate the public further about invasive species, and put in physical work to help fight the spread of invasive Asian clam in Lake George. Invasive Species Awareness Week

Organized by the Adirondack Park Invasive Plant Program, the Adirondack Park’s Sixth Annual Invasive Species Awareness Week was held the second week in July. As part of the week’s events, from Monday, July 11th to Friday, July 15th a display was set up outside of Lake George Village’s Visitor’s Center from 11am to 4pm. Multiple tables were arranged and stocked with information about both terrestrial and aquatic invasive species to raise awareness of the threat of invasive species. Representatives from Cornell Cooperative Extension, New York State Department of Environmental Conservation, and the Lake George Association spoke with visitors about the threats faced by the Adirondack Park, and the role that visitors can Above: Invasive species awareness week display setup play in spread prevention. at the Lake George Visitor’s Center

In addition, events were hosted across the park to further educate the public, such as plant identification and forest pest workshops, family programs, interpretive walks and aquatic plant paddles.

Live specimens of invasive species were available for the public to see and touch. A main issue the lake stewards addressed during 2011’s invasive awareness week was the newly introduced invasive Asian clam. Stewards were able to show the public how to identify the clam, and what they could do to help survey for it, and stop its spread.

Asian Clam Eradication Effort

In fall 2010, the aquatic invasive species Asian Clam, Corbicula fluminea, was found in the Village of Lake George. Extensive systems of benthic barriers held down by rebar and sandbags were laid over six acres of sandy substrate to suffocate the calms in spring 2011.

Lake stewards assisted in the Asian clam effort on numerous occasions throughout the summer by aiding with the filling, transporting, and placement of sandbags and with the removal of the barriers. Stewards also helped survey for Asian clams around Lake George. They worked along side members from organizations of the Lake George Asian Clam Rapid Response Task Force (LGACRRTF), a committee made up of representatives from Adirondack Park Agency, Adirondack Invasive Plant Program (APIPP), Darrin Fresh Water Institute, Lake Champlain Basin Program, Lake George Association, Lake George Park Commission, Lake George Watershed Coalition, NYS Department of Environmental Conservation, The FUND for Lake George, and the Nature Conservancy’s Dome Island Committee.

Asian clam, Corbicula Fluminea, is a small bivalve that is native to southern Asia, the eastern Mediterranean, and Australia. They are small, usually less than 1.5 inches in size, and have a light tan or brown shell with distinctive concentric ridges.

Asian Clam Eradication Effort

In early June, armed with shovels, lake stewards filled over 200 sandbags, with sand from the Village of Lake George, that were used to hold down the benthic mats at the eradication site in the southern end of Lake George.

After filling the bags, the stewards helped to transport them to the site via pick-up trucks and unloaded them. At the Lake Avenue Asian clam site on Lake George, stewards helped place the bags on the mats surrounding the shoreline.

In mid-June, lake stewards returned to the infestation site to help volunteers from LGACRRTF pull up the first layer of benthic mats by taking off rebar and sandbags, and rolling the mats up in the water.

In July, lake stewards assisted teens from Beckett-Chimney Corners, a volunteer group working with the Lake George Association, in filling more sandbags needed for the infestation site. Over two full days of work, approximately 2,300 sandbags were filled.

Fishing Tournaments

During the summer season, Lake George has a few fishing tournaments around the lake. These tournaments give lake stewards the ability to provide outreach and education to organizations of anglers who frequent a higher number of waterbodies than the average boater.

Mossy Point hosted three fishing tournaments throughout the course of the summer on June 19, June 26, and August 7. On both June 19 and June 26, stewards were present the day prior to the tournaments to collect data and inspect boats. However, these tournaments consisted of more than 100 boats each. On the day of the tournament, stewards inspected boats but did not collect data as to not impede the progression of the tournament. On August 7, stewards collected data, inspected boats, and spoke with anglers regarding the spread of invasive species as usual due the low volume of boats attending this tournament.
