Dear Friends of Maine Lakes,

This report on the health of Maine lakes reflects the effort of more than 1,000 volunteer citizen scientists who monitored several hundred lake basins throughout the State in 2012. Many of them have been doing so continuously for decades, and a few have been involved for most of the 42 years since the Maine Legislature officially authorized volunteer lake monitoring. Their work is a strong testimony to the level of public commitment in Maine to our clear, clean lakes, and it is probably not coincidental that our lakes have remained as healthy as they have under the watch of these individuals. The Maine Volunteer Lake Monitoring Program (VLMP) is believed to be the longest-standing statewide citizen lake monitoring program in America, having been formed at about the time of the passage of the historic Federal Clean Water Act. The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities. Our primary partners are the Maine Department of Environmental Protection (DEP) and the US Environmental Protection Agency, which provide a wide range of financial, technical and management support to the program. In turn, the VLMP provides these agencies with essential information that they use to manage and protect Maine’s lakes. The relatively small investment of public funding that supports the work of the VLMP is multiplied in value several times through the invaluable, high quality work of VLMP volunteers, and from increasing private support from individuals, organizations and businesses who recognize the tremendous benefits to Maine lakes. Studies conducted throughout the country have consistently shown that lake data gathered by properly trained volunteers are equivalent to, and indistinguishable from that of professional lake scientists, at a fraction of the cost! The additional invaluable benefit of public education and stewardship that VLMP volunteers provide to communities throughout the state is one of Maine’s best examples of grassroots natural resource protection. The effectiveness and strength of the VLMP is in part due to collaborative partnerships with other entities, including agencies and organizations throughout Maine and the U.S. This collaboration has formed a powerful resource for technical expertise, outreach, and access to a great deal of information concerning Maine lakes and their watersheds. Since the earliest days of the program, the VLMP has been at the forefront of gathering lake data in Maine and the U.S. For more than four decades, the total number of active individuals involved in monitoring water quality, and in screening public waters for invasive aquatic species has increased steadily. This document is a testament to their remarkable commitment!

i VLMP Program Overview

Mission: The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities. Introduction Maine’s 5,785 lakes and ponds, about half of which are in the public domain, are among the most pristine in the nation. Lake scientists have long recognized that protecting and keeping lake ecosystems healthy requires knowledge of a large and broad cross-section of waterbodies. For 42 years, Maine’s Volunteer Lake Monitoring Program has risen to the challenge by collecting a substantial percentage of the annual water quality data for Maine lakes. As new threats have presented themselves, such�� as invasive aquatic species, VLMP�� volunteers have expanded their level of commitment and stewardship. Recognition of the relationship between healthy lakes and Maine’s economy is well established. Information collected by VLMP volunteers has greatly contributed to this understanding. In 2012, volunteers collected water quality data from 415 Maine lakes across the state. As of Volunteers receive training and are certified through the 2012, 449 waterbodies across the State of Maine have also VLMP. Depending on personal interests and program been screened, at some level, for the presence of aquatic needs, a number of training and monitoring options are invaders.

Reliable information about Maine lakes, both individually and collectively, is the foundation of all efforts to protect, manage and restore these resources. Program Structure and Administration The VLMP is structured to optimize volunteer participation in both data acquisition and program administration. This reduces the cost of operations, increases feedback to program administrators from volunteers, and strengthens local stewardship. The VLMP is governed by a volunteer Board of Directors. The Board has approved by-laws and a regularly updated Strategic Plan. Board meetings are held several times throughout the year and are open to the public. The VLMP also has volunteer Regional and Data Coordinators that assist with program management at various levels by organizing re-certification workshops, collecting data forms, entering data into the data- Maine Lakes with base, maintaining contact info for the volunteers, and VLMP Volunteer Monitors in 2012 responding to volunteer requests for equipment and monitoring forms.

Assurance and Quality Control All data, including volunteer-collected information, are useful only when accurate, of acceptable quality, and reliably collected. In order to ensure that the lake water quality data collected by the VLMP are credible, all contributors of this data must meet specific technical standards. This system of quality assurance, and the standards that must be followed by volunteers, staff and others who participate in the gathering and processing Photo by Linda Bacon by Photo of data, is commonly known as "QA/QC" (quality Volunteer water quality monitors review Dissolved Oxygen monitoring assurance/quality control).

The primary role of the Maine DEP partnership with the VLMP is to provide QA/QC guidelines and standards for data collection and management. The DEP staff serve as quality control agents, providing technical support to VLMP staff, as required. The VLMP and DEP staff work cooperatively to ensure that available resources are used efficiently.

Water Quality How Do Volunteers Monitor Lake The enrichment of lakes with the nutrient phosphorus and excess algae, resulting from watershed development, is Water Quality? referred to as "cultural eutrophication" (CE).

Measuring Lake Water Clarity (Transparency) With A Secchi Disk

One simple method of assessing the effect of cultural eutrophication in lakes is to measure the concentration of planktonic (suspended) algae in the water. Algae are at the base of the lake ecosystem food web. Volunteer water quality monitors begin monitoring their lake by measuring Secchi disk transparency. The Secchi disk is a simple device that is used to estimate algal concentrations, a disturbance to the normal equilibrium of the aquatic based on water clarity. Volunteers in the VLMP are ecosystem.

Oxygen in lake water is also influenced by wind and wave action through weather events and the exposure of surface water to atmospheric sources. An adequate supply of dissolved oxygen in lake water is essential to fish and other aquatic life forms. DO is also a sensitive indicator of change in water quality, and of the ability of a water body to support aquatic life. The loss, over time, of DO in the deep areas of a lake, especially during summer months, may indicate that the ecosystem is stressed and changing. Biological activity peaks in lakes and ponds during the warm weather months. It is also at this time that the phenomenon of thermal stratification (see Figure 3) occurs. The combined influence of the two processes has a pronounced effect on water chemistry, and in particular on dissolved oxygen levels.

During the first few years of this period the number of lakes on which the average is based was relatively small.

Since 1975, the number of lakes used to determine the annual average Secchi Depth (meters) has increased steadily to more than 400 per year.

Since the first (bottom photo and inset). IPP workshop in 2001, the number of waterbodies with reported IAP survey activity has increased from one to 458. Every year, the percentage of IAP surveys conducted by trained IPP volunteers has grown. In 2012, VLMP Invasive Plant Patrollers were responsible for 94% of all reported IAP survey activity in Maine. In addition to the IPP program, a number of publications, hand-outs, web-resources and curricular materials have been developed by the VLMP to support widespread engagement in Maine’s early detection efforts. These resources include: Maine Field Guide to Invasive Aquatic Plants, Quick Key to Ruling out Maine’s Eleven Most Unwanted Invasive Aquatic Plants, the Friend or Foe Learning Kit, Aquatic Species Identification Cards, and the online IPP Leaders’ Page and Virtual Herbarium. Rapid Response and Management Once an infestation has been confirmed, rapid response is crucial. The prospects for eradication (or barring that, effective management at minimum risk to the aquatic ecosystem), is greatly increased by swift, well-planned, and properly executed controls. In developing an invasive aquatic plant management plan, one of the most important questions to be answered is, “How, exactly, is the invasive plant infestation to be controlled?” The principal approach in Maine is manual control. Manual control methods may alternately be referred to as “non-chemical,” “physical” or “mechanical” methods. The three primary manual control methods being used in Maine are: manual harvesting, benthic barriers, and diver assisted suction harvesting (DASH). the program, SCUBA divers and non-divers receive a certi- VLMP has been a key player in the development of fication card and may elect to be formally listed on Maine’s Maine’s ability to respond swiftly and effectively to new Rapid Response Team list.

Invasive Plant Patrollers are making a difference! Case in point…

The VLMP initiated the Moosehead Lake Invasive Plant Patrol Jump-Start in 2008, for the purpose of 1) “jump-starting” citizen-based lake monitoring in a region where such activity was currently lacking, and 2) screening Moosehead Lake for the presence of invasive aquatic plants. Over the past five years, the Moosehead Lake Invasive Plant Patrol Jump- Start team (comprised primarily of Certified IPPs, with state agency personnel and VLMP staff) has scoured the shoreline of Moosehead Lake for aquatic invaders (happily finding NONE); conducted a comprehensive inventory of Moosehead Lake’s native aquatic plants (finding MANY--110 species!); and worked to engage the local community in efforts to prevent the spread of aquatic invaders to this ecologically- rich and economically-vital region of the State. This year, videographer Steve Underwood joined the team and captured the story in extraordinary high-definition footage taken on, around, and under the surface of Moosehead Lake. The resulting VLMP documentary “The Hunt for Aquatic Invaders” is scheduled for release this summer.

2013 Updates 29 Appendix A Long-term Distribution of Water Quality Data for Maine Lakes The data illustrated in Appendix A are based on the long-term means (average of all historical annual averages) for each parameter measured in Maine lakes. Appendix A contains histograms (a graph that shows how the data are distributed for a particular variable) of the indicators of lake water quality for the lakes that have been included in each data set. The number of lakes sampled (N) varies for each lake quality indicator. The range of means (minimum-maximum), the statewide mean (mean), and the number of lakes sampled are shown with each graph. As you view this information, please be aware that lake water quality for individual lakes, and for all Maine's lakes varies from year to year. However, the distribution of data in these graphs shows little change from year to year, because of the cumulative (multiple years) nature of the information being illustrated. Water quality indicators for individual lakes may show substantial annual variation.

44 Appendix C Range of 2012 Average Secchi Disk Transparency for VLMP Lakes

The following is a listing of the mean (average) annual Secchi Disk Transparency values in 2012 for VLMP lakes. Readings are arranged from the lowest to the highest values.

Key to Appendix C column headings

AVE Annual average Secchi Disk Transparency (SDT). A * indicates that the Secchi Disk was visible at the bottom of the lake on one or more readings. Measurements are in meters.

N Number of months a volunteer collected SDT readings over the 2012 season. The greater the number of months that readings were taken (N) for the year, the more likely it is that the average for the year is representative of conditions in the lake during the entire annual monitoring season.

MIDAS Unique four digit identification code for each Maine lake.

STA Refers to the sample station location on the lake. Station 1 generally refers to the deepest location in the lake basin. A volunteer monitor takes a COUNTY & TOWN Note some lakes are in multiple towns or counties. Secchi Disk Transparency reading.

Explanation of Individual Lake Report and Sample Report Individual lake reports, created by Maine DEP, include data that are provided by the VLMP. These reports include information about the lake and its watershed, water quality annual data summaries, historical water quality summary information and a narrative summary. Individual lake reports are provided to volunteers and are available on the VLMP website www.MaineVolunteerLakeMonitors.org

EXPLANATION OF LAKE WATER QUALITY MONITORING REPORT

This report contains summaries for variables most often used to measure the water quality of lakes and ponds in Maine. These variables are relatively inexpensive to measure, and are easily monitored by volunteers in the Volunteer Lake Monitoring Program and staff of the Department of Environmental Protection. Minimum and Maximum values are from entire DEP dataset.

SECCHI DISK TRANSPARENCY AND GRAPHS: Secchi Disk Transparency (SDT) is a measure of the water clarity, or transparency, of the lake. All Secchi disk readings are in meters [1 meter (m) = 3.28 feet]. Factors which reduce clarity are algae, zooplankton, water color and silt. Since algae are generally the most abundant, measuring transparency indirectly measures the algal productivity. SDT readings can be used to track changes in water quality over time. Transparency values in Maine vary from 0.2m (8 inches) to 21.27m (70 ft), with the overall average being 4.83m (15.8 ft). Unless a lake is highly colored (see explanation of color below) or some other factor is interfering, a transparency of less than 2m (6.6 ft) indicates a water quality problem that has resulted in an algal bloom. In Maine, the mean (average) SDT readings are related to algal productivity using the following guidelines: Productive = 4m (13 ft) or less; Moderately productive = 4.1-7.9m (13-26.5 ft); Unproductive = 8m (26.5 ft) or greater.

Usually two transparency graphs are displayed in the report. The first graph is provided if data were collected the previous year and illustrates the seasonal variation that can occur during the monitored months. The second graph represents the average SDT readings for each year data is available. The bars or tick marks on this graph represent the minimum and maximum Secchi disk readings for that year. This graph allows tracking of water quality over many years.

MIN. = minimum or lowest Secchi disk depth recorded for that year. The summary line has the lowest Secchi disk reading ever recorded for that lake. MEAN = Average of monthly averages of Secchi disk reading for that year. The summary line would show the average for all years datasets have been taken. MAX. = Maximum or deepest Secchi disk reading taken for that year. The summary line displays the deepest reading ever recorded for this lake. N = number of months readings were taken that year. Summary N = number of years of data.

SUMMARY OF CHEMICAL AND TROPHIC STATE PARAMETERS:

COLOR: The amount of “color” in a lake refers to the concentration of natural dissolved organic acids such as tannins and lignins, which give the water a tea color. Color is measured by comparing a sample of the lake water to Standard Platinum Units (SPU). Colored lakes (>30 SPU) can have reduced transparency readings and increased phosphorus values. This does not mean the lakes are more productive, the color simply interferes with the test so better results can not be achieved. Chlorophyll a (Chla) is the best indicator of productivity in colored lakes and should be used if possible. Color varies from 1 to 630, with the average in Maine being 28 SPU. pH: The pH of a lake reflects how acidic or basic the water is and helps determine which plant and animal species are present. The measure of the acidity of water is based on a scale of 1-14, with 7 being neutral. Acid waters are below 7; alkaline waters are above 7. Epilimnetic pH varies, from 4.23 to 9.70, the average being 6.81. A one unit change in pH represents a 10 fold change in acidity or alkalinity.

53 Appendix D - Explanation of Individual Lake Report and Sample Report

ALKALINITY: Alkalinity is a measure of the capacity of water to neutralize acids and is also known as the buffering capacity. It is due primarily to the presence of naturally available bicarbonate, carbonate, and hydroxide ions, with bicarbonate being the major form. Epilimnetic alkalinity in Maine varies from -1.5 milligram per liter (mg/l) to 190.0 mg/l, with the average being 12.0 mg/l.

CONDUCTIVITY: Conductivity is a measure of the ability of water to carry an electrical current and is directly related to the dissolved ions (charged particles) present in water. Epilimnetic conductivity varies from 2 µmhos/cm to 7900 µs/cm, with the average being 46 µs/cm. Fishery biologists use conductivity values to calculate fish yield estimates. Conductivity will increase if there is an increase of pollutants entering the lake or pond.

TOTAL PHOSPHORUS MEANS (ppb): Total Phosphorus (TP) is one of the major nutrients needed for plant growth. It is generally present in small amounts and limits the plant growth in lakes. It is measured in parts per billion (ppb). As phosphorus increases, the amount of algae also increases. Epilimnetic TP varies from 1 ppb to 426 ppb with the average being 12 ppb. EPI CORE = Epilimnetic core sample (mixed sample from epilimnion) was taken; SURF GRAB = Surface grab sample taken; BOT. GRAB = Bottom grab sample taken (1 m above bottom of lake), PRO. GRAB = Profile grab samples taken and averaged.

CHLOROPHYLL A (ppb): CHLOROPHYLL A (Chla) is a measurement of the green pigment found in all plants including microscopic plants such as algae. It is used as an estimate of algal biomass, the higher the Chla number the higher the amount of algae in the lake. Epilimnetic Chla, varies from 0.10 ppb to 238 ppb, with the average 5.3 ppb. MIN. = minimum or lowest Chla depth recorded for that year. Summary has the lowest Chla reading ever recorded for that lake. MEAN = Average Chla reading for that year. Summary shows the average for all years data has been taken. MAX. = Maximum or highest Chla reading taken for that year. Summary displays the highest reading ever recorded for this lake.

TROPHIC STATE INDICES: The Trophic State Index (TSI) is a scale which ranks lakes from 0 to 100+ with 0 supporting very little algae and 100+ being very productive. TSI can be calculated from the Secchi disk, Chla or total phosphorus results. TSI for a year is only calculated when there are at least five months of data. Lakes with TSI values greater than 60 may support blooms (less than 2m SDT). Lakes with TSI values over 100 indicate extreme productivity and annual algal blooms. TSI values can be used to compare lakes and track water quality trends within a lake. Lakes with color over 30 SPU will only have a valid TSI if the value is calculated from Chla. The range of TSI in Maine is from 5-136 with an average of 45. EPI PHOS = Epilimnetic Phosphorus samples taken to determine the TSI; C = core G = grab samples taken; SEC = TSI value calculated using the mean Secchi disk value (water color < 30 SPU to ensure valid TSI); CHL = TSI calculated using the mean Chla.

LATE SUMMER TEMPERATURE / DISSOLVED OXYGEN PROFILES: Dissolved Oxygen (D.O.) is the measure of the amount of oxygen dissolved in the water. All living organisms, except for certain types of bacteria, need oxygen to survive. Organisms living in the water have the ability to use the oxygen dissolved in the water to breathe. Too little oxygen severely reduces the diversity and population of aquatic communities. Therefore the amount of D.O. in the water is very important to aquatic life. Low oxygen can directly kill or stress organisms such that they will not be able to successfully reproduce or grow. Water with less than 1 part per million (ppm) of oxygen is considered anoxic (no oxygen present); less than 5 ppm of oxygen is generally considered so stressful that most coldwater fish will avoid these areas. Anoxic conditions can also promote TP release from sediments.

Temperature is the measure of heat in the water and can affect the water's chemistry and biology. For example, the amount of oxygen water can hold is directly related to the temperature of the water. The higher the temperature the less oxygen the water can hold. Oxygen will naturally decline during the summer months as water temperatures rise. Lakes deeper than 25-30 feet can also stratify, with warm water riding over cooler deep water, restricting circulation in the lake. This can contribute to oxygen loss in the lower waters. Temperature can also determine the kinds of plants and animals found in the lake or pond. Certain species of fish, insects and algae will predominate during the cooler temperatures of the spring and fall, yet disappear during the warmer temperatures of summer. For instance, salmo- nids generally prefer temperatures below 18oC (65oF) but can tolerate slightly higher temperatures for short periods of time. However, constant exposure to temperatures of greater than 18oC (65oF) may result in some fish being more susceptible to disease or not being able to reproduce as well. Conversely, other more tolerant species will predominate during the more stressful summer months. The late summer temperature and dissolved oxygen profiles in data report represent the lake’s most stressed open water period. m = Depth data was recorded, in meters; oC = Temperature in degrees Celsius; Date is sampling date; ppm = Dissolved oxygen reading in parts per million (ppm).

57 Appendix E Invasive Aquatic Plant Screening Survey Activity Reported: 2002-2012 Note: The number of waterbodies with infestations in this table may differ from the official DEP listing. This is generally the result of one list grouping infested waterbodies (e.g. Messalonskee Lake and Belgrade Stream) and the other listing waterbodies separately.

Key to Appendix E MIDAS refers to the unique four-digit identification code for a lake. Year Surveyed: Survey data is organized by the year in which the survey was completed. Blank cells indicate survey data not reported for that year. For surveys conducted between 2002 and 2012, activity is indicated with a single dot (●) only. More detailed information for each year of reported survey activity on a given waterbody can be found on the VLMP website. Visit the VLMP Lake Search at www.MaineVolunteerLakeMonitors.org/lakes to find more survey information for the lake of interest. Survey Data: Surveys for 2012 are characterized by a listing of abbreviations under the following columns: Survey Level, Surveyor Type and Certified. The Survey Level and Surveyor Type abbreviation explanations are below. Survey Level refers to the scope of the survey conducted. In several cases, more than one level was conducted either during the same year, or from one year to the next. The following abbreviations are used to indicate survey level: LT Limited: Only a relatively small portion of the littoral zone of the waterbody was surveyed. 1 Level 1: The high risk areas such as points of public access, marinas, etc. were surveyed, including at least 100 meters (~300 feet) on either side of the high risk area, and extending into the lake to the outermost depth or the littoral zone or a depth of at least 4 meters (~13 feet). 2 Level 2: The Level 1 areas were surveyed, plus the areas of the shoreline that were likely to provide suitable habitat for aquatic plants, such as shallow, sheltered coves. 3 Level 3: Entire shoreline area and littoral zone was surveyed. IS Infestation Surveillance: This�� is now a survey level descriptor indicating a known infestation is being monitored but not mapped in detail. RA Rapid Assessment: This refers to the Rapid Assessment screening survey methodology developed by the Maine Natural Areas Program; at a minimum, the inlet, outlet, boat launch areas and 1/3 of the total littoral zone were surveyed. In some cases a full Level 3 survey was conducted. Surveyor Type refers to the individual or group conducting the survey. In some cases multiple surveyors conducted surveys. The following abbreviations are used: Prf Professional: Trained professional, usually hired by the lake association and/or stakeholders Rsr Researcher: Students and/or faculty of a research institution (such as college or university) Agn Agency Personnel: Staff from various public or quasi-public agencies. Example agencies are the Maine Department of Environmental Protection, and Maine Department of Conservation Natural Areas Program, Auburn Water District. Vol Volunteer: Invasive Plant Patrol trained volunteer (or team of volunteers) Certified refers to whether a survey was conducted by a Certified Invasive Plant Patroller. A ‘Y’ in the “Certified” columns represents a yes. IAP Conf indicates waterbodies in which Invasive Aquatic Plants have been confirmed, and identifies which invasive species are present. Invasive Species are abbreviated as follows: CP Curly Leaf Pondweed (Potamogeton crispus) EM Eurasian Water-milfoil (Myriophyllum spicatum) EN European Naiad (Najas minor) HY Hydrilla (Hydrilla verticillata) VM Variable Water-milfoil (Myriophyllum heterophyllum) VMh Variable Water-milfoil Hybrid (Myriophyllum heterophyllum x M. laxum) ( ) Parentheses indicates successful eradication, followed by year removed from State List of Infested Waterbodies

2012 Certified Volunteer Lake Monitors Listing of all certified volunteer lake monitors in the VLMP in 2012, including each volunteer’s ‘Years of Service’ listed after their name. The list is organized by county and then by lake name.

In 2012 the VLMP trained and certified 31 new volunteers to monitor lake water quality, and 126 Invasive Plant Patrollers became certified.

Many VLMP volunteers have been continuously active for more than a decade, and a growing number have been monitoring their lakes for 10, 15, 20 and even 25 years!

90 Glossary

Secchi disk: A black and white disk that is used to measure water transparency.

Surface Grab: A water sample taken from the lake surface.

Thermal stratification: As lake water is warmed in the summer the water in a deep pond or lake is layered into three levels: 1) warmer (less dense) epilimnion layer at the surface; 2) the thin thermocline or transition layer; 3) the cold and deep hypolimnion layer.

Thermocline: The narrow transition zone between the epilimnion and hypolimnion.

Total phosphorus: A measure of all forms of phosphorus (organic and inorganic) in the water.

Transparency: A measure of water clarity that, in lakes and ponds, indirectly measures algal productivity. Transparency is determined by the depth at which a Secchi disk lowered into the water column is no longer visible.

Trophic State Index: A simplified index of biological productivity in lakes.

Turbidity: The degree to which light in water is blocked because the water is muddy or cloudy. In general the turbidity of a lake is directly related to the amount of algae present in the water.

Turnover: The process of mixing that occurs in many lakes and ponds in the spring and fall of the year. Turnover takes place when the water temperature is uniform from the surface to the bottom.

Watershed: A region or area divided by points of high land that drains into a specific water body.

Water Column: A conceptual column of water from the surface of a water body to the bottom sediments.
