Project Title Lake Ballinger Invasive Aquatic Species Control
Project Dense growth of Eurasian Short Description watermilfoil and fragrant water lily, along with a smaller infestation of curly leaf pondweed have impacted both recreational use and overall water quality in Lake Ballinger. The proposed management strategy to control these invasive aquatic weeds uses a combination public education; cutting, raking, and burlap bottom barriers; and herbicide application to 25% of the lake littoral zone over a period of 4 to 8 years.
Project Lake Ballinger is located Long Description in southwestern Snohomish County, Washington. Three-fifths of the lake is located in the City of Mountlake Terrace, and two-fifths of the lake is located in the City of Edmonds. The watershed extends into King County, and includes land within five incorporated cities (Edmonds, Lynwood, Mountlake Terrace, Shoreline, and Lake Forest Park) as well as unincorporated land belonging to Snohomish County.
Lake Ballinger is a popular site for recreation and is frequently used by
11/14/2018 Page 1 of 8 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 General Information
the public and residents with private land abutting the lake. There is a public fishing dock and swimming beach on the Mountlake Terrace side of the lake. Beneficial uses of Lake Ballinger include swimming; fishing; non-motorized boating; aesthetic value; fish migration; resident fish spawning and rearing; commercial irrigation water supply; and aquatic habitat. The lake is eutrophic, and in recent years, dense growth of aquatic invasive plants in Lake Ballinger has severely impeded recreational beneficial uses and negatively impacted the aquatic habitat in the lake. Chemical methods have not been used to control aquatic vegetation in Lake Ballinger, though in the 1990s an alum treatment was administered in an attempt to control algae blooms. Lake residents have employed some manual control methods for aquatic weeds, including cutting and raking.
Concerns about the dense growth of aquatic weeds caused lake residents to bring the problem before the Lake Ballinger/McAleer Creek Watershed Forum. In the fall of 2017, the City of
11/14/2018 Page 2 of 8 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 General Information
Mountlake Terrace and the City of Edmonds applied for and were awarded a grant from the Washington Department of Ecology to survey the lake’s aquatic vegetation and to write a plan to control invasive species.
In late June 2018, Tetra Tech conducted a survey of aquatic plants in Lake Ballinger. In addition to two native species (Yellow pond lily [Nuphar lutea] and large leaf pondweed [Potamogeton amplifolius]), the survey identified three non-native, noxious weed species: Fragrant water lily (Nymphaea odorata), Eurasian watermilfoil (Myriophyllum spicatum), and curly leaf pondweed (Potamogeton crispus). Snohomish County has designated Eurasian watermilfoil a class B Noxious Weed. This designation requires control. Fragrant water lily and curly leaf pondweed are class C noxious weeds in Washington State. A secondary survey in Hall Lake, upstream of Lake Ballinger, identified the non-native, noxious plant variable-leaf milfoil (Myriophyllum heterophyllum). Variable-leaf milfoil is a class A noxious weed in Washington State. This designation mandates
11/14/2018 Page 3 of 8 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 General Information
eradication of the species.
In Lake Ballinger, management of aquatic invasive plant species will prioritize public shorelines and nearshore areas (out to approximately 11 to 12 feet deep). This includes the shoreline and lake littoral area along the north and northeast portions of the lake. Secondary priority target areas include the shorelines and nearshore areas along the western and southwest portions of the lake which are mostly privately owned residential land. The shoreline and littoral area surrounding the island and along the golf course and southeast portion of the lake are of lower priority. Hall Lake is not included in the management area for this Plan, but as it is upstream of Lake Ballinger, monitoring for non-native species that could spread downstream to Lake Ballinger will be conducted. Additional survey and monitoring for non-natives will also be conducted along the length of Hall Creek and in the in-creek stormwater ponds downstream of Hall Lake.
The recommended plan is to apply approved herbicides to the target areas in Lake Ballinger
11/14/2018 Page 4 of 8 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 General Information
over the course of 4 to 8 years, depending on the availability of funding. Following the first 4 to 8 years of management, maintenance herbicide spot treatments may be necessary, but the need for extensive herbicide coverage should be significantly reduced. One quarter of the shallow lake (littoral) area will be treated each year. High priority target areas will be treated first, followed by secondary and lower priority areas. Small areas may be re-treated if necessary to achieve carry-over control, but the acreage treated each year will not exceed 25% of the littoral area. This phased approach was designed to mitigate the release of nutrients into the water column as treated plants decay and thereby reduce the potential for herbicide treatments to trigger an algal bloom in this historically eutrophic lake. Chemical control of aquatic invasive plants will be supplemented by volunteer efforts to cut and rake invasive species and to install bottom barriers (burlap sandbags). This "hands-on" volunteer approach will be used as much as possible, but due to the large area of the invasive plant infestation, herbicide application is
11/14/2018 Page 5 of 8 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 General Information
also necessary to control the spread of aquatic weeds.
The proposed alternative will target invasive species in areas where beneficial uses are currently impeded by excessive plant growth. It is anticipated that the strategy will improve water quality, increase recreation use, and also increase other beneficial uses of the lake. In addition, controlling the population of invasive aquatic plants will improve conditions for native aquatic plants, improving the quality and diversity of available aquatic habitat.

Task Number 2
Task Title Public Outreach and Education Task Cost $3,000.00*
Task Description Outreach to both individual lake residents/groups of lake residents and lake recreational users about the reasons why control of aquatic invasives is necessary, and options for manual control of invasive aquatic species (using the methods described in the WDFW pamphlet "Rules for Aquatic Plant Removal and Control".) The public outreach plan will also include delivery of one or more workshops for property owners on how to use the WDFW pamphlet, including on using cutting, raking, and sand-filled burlap bottom barriers to reduce the density of aquatic invasive plants in Lake Ballinger; and on more information regarding new EPA-approved herbicides (such as Procellacor). The workshop(s) will also provide instruction on basic plant identification for common invasive and native plants known to reside in Lake Ballinger, and education on methods to control the spread of invasive plant species to other lakes by using best management practices such as those detailed in "Minimize the Spread of Invasive Species", Department of Ecology SOP EAP070, Version 2.2. Additional public outreach will be provided through presentations to the regularly-scheduled and special meetings of the Lake Ballinger Watershed Forum, through social media outlets (Facebook, Twitter, and Instagram), city newsletters, through list serves and email groups set up by lake residents, and by word of mouth. Additional information will be spread through notification signs for the herbicide application.
Task Goal Statement To inform and educate lake users and lake residents about the IAVMP and their role in controlling invasive plants in Lake Ballinger.
Task Expected Outcomes Lake residents and volunteers know how to identify invasive aquatic weeds and are empowered to use manual methods to reduce invasive plant infestation effectively. They are aware of the pros and cons of new EPA-approved herbicides to target Eurasian milfoil and other invasive species. Swimmers and other recreational users, as well as lake residents, are aware of the reasons why herbicide was chosen by the steering committee as a method to control aquatic weeds in Lake Ballinger, and have an opportunity to ask questions and receive answers about the control options considered.

Task Number 3
Task Title Herbicide Treatment & Monitoring Task Cost $35,000.00*
Task Description Document the incidence and density of aquatic plants prior to herbicide application, after herbicide application is complete for the season (12-18 weeks after initial application), and again in the spring during the max plant growth season. Hire aquatic herbicide applicator to safely apply EPA-approved herbicide(s) to 25% of the littoral zone of Lake Ballinger annually to control aquatic invasives. Monitor lake water for herbicide concentration in application area, near water intake for Nile Golf Course, on south end of the lake, at McAleer Creek outlet to lake, and near swimming beach. Use protective measures to avoid the Nile Golf Course water intake from receiving herbicide. City to initiate herbicide application permit, advertise for, and select herbicide applicator provider. Edmonds and MLT will also notify lake residents through city website, mailing addresses, and any available email lists when herbicide will be applied. Herbicide applicator to provide all required posting, notification, and herbicide residual monitoring to meet permit requirements.
Task Goal Statement Control Eurasian watermilfoil, Fragrant water lily, and Curly leaf pondweed populations in target areas. Assess success of the control efforts through evaluation of invasive plant density before and after treatment. Notify lake residents as per permit requirements when aquatic herbicides are being applied. Monitor residual herbicide in the lake and McAleer Creek (lake outlet) to determine concentration.
Task Expected Outcomes Substantial reduction in population of specific invasive aquatic species in the area targeted with herbicide, as demonstrated by records of aquatic plant surveys prior to herbicide application, after herbicide application is complete for the season (12-18 weeks after initial application), and again in the spring during the max plant growth season.

11/14/2018 Page 1 of 1 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 Aquatic Invasive Plant Project
1 - Is there an Ecology approved Integrated Vegetation Management Plan for this project area? Unknown If yes, provide the name of the IAVMP and the date submitted: Lake Ballinger IAVMP, submitted 10/09/2018. Attached version was modified based on Ecology review.
2 - Is there a qualifying boat ramp for this waterbody? Yes
3 - What is the level of infestation? (species #1) Heavy (dense growth in most areas along shoreline)
4 - Is the project in a waterbody with an ESA listed species or critical or depressed salmon stocks? Yes
If yes, how will the aquatic invasive plant treatment be taken care of? According to the WDFW Priority Habitat and Species Program, coho salmon (Oncorhynchus kisutch) also occur and breed in Lake Ballinger and its outlet, McAleer Creek (WDFW 2018). The control strategy proposes using a combination of manual methods (raking and sand-filled burlap bags) for small areas, combined with EPA-approved herbicide application to no more than 25% of the littoral zone per year. These measures are designed to minimize any harm to fish populations.
5 - Please list all known aquatic and emergent invasive plants known in the project area. Eurasian watermilfoil, fragrant water lily, curly leaf pondweed. Possible variable-leaf milfoil.
6 - Does this invasive plant(s) pose a threat to other nearby waterbodies? Yes
If yes, explain: Lake Ballinger is upstream of Lake Washington, and is directly connected to it via McAleer Creek. Fragments of Eurasian watermilfoil or fragrant water lily could be swept downstream and further complicate the existing efforts on Lake Washington to control those weeds. There is also a well-established population of variable-leaf milfoil in Hall Lake, directly connected to Lake Ballinger by Hall Creek, and we are concerned that fragments of this weed may also be transferred downstream.
7 - What impacts will this invasive plant have on water quality and habitat? Water quality has been degraded in areas of Lake Ballinger with thick invasive plant growth due to increased nutrient recycling of phosphorous and nitrogen, as well as increased oxygen demand. This decreased water quality may also affect fish migration and resident fish spawning and rearing. Fish, waterfowl, and plant habitat diversity has been negatively impacted through the
11/14/2018 Page 1 of 3 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 Aquatic Invasive Plant Project
"crowding out" of native plant populations and establishment of a near-monoculture of invasives in the littoral zone.
8 - What impacts will this invasive plant have on public use and recreation? Increased invasive aquatic vegetation has negatively impacted recreational activities, water quality, and aquatic habitat in Lake Ballinger in recent years. Lake residents and users have reported that they no longer enjoy activities such as boating, kayaking, canoeing, swimming, and fishing due to entanglement in the plant growth. Decaying aquatic plants can also reduce water clarity and can create unpleasant odors. Lake aesthetic values are also impacted.
9 - What decontamination measures will you implement to keep from spreading invasive species? We intend to follow the Ecology SOP EAP070, Version 2.2 "Minimize the Spread of Invasive Species" (March 2018), including the protocols to decontaminate boats, trailers, waders, and any other field equipment. Before leaving the site, all buckets, coolers, waders, boots, and any other equipment that can hold water will be drained. All boat axle and wheel wells, motor, propeller, anchor, ropes, waders, and paddles will be checked and any plant materials or mud removed.
10 - What environmental and/or economic damage may be caused by not eradicating/containing the invasive plant? By not containing the invasive plants in Lake Ballinger, water quality and habitat will continue to degrade, beneficial uses will continue to be impaired, lake aesthetics will continue to diminish, and economic damage will be realized in the form of reduced lakeside and lake view property values. Invasive species will continue to dominate the vegetation community, and native aquatic plant populations will continue to be suppressed.
11 - How committed are you to continue working on the control/eradication portion of this project after the completion of this IAVMP? Very committed. The lake residents, along with Mountlake Terrace and Edmonds staff, are working together through the Lake Ballinger watershed forum to implement the control options identified in the IAVMP. City of Edmonds staff are leading the creation of a long-term funding source for control efforts through re-scoping and reformation of the existing Lake Ballinger management district, allowing lake residents to tax themselves for on-going aquatic invasive plant control efforts.
12 - Do you have local citizen support for this project? Yes, the problem was first identified by lake residents, and the recommended control approach was developed by citizens as part of the IAVMP steering committee, with the approval and enthusiastic support of the Lake Ballinger/McAleer Creek Watershed Forum. The Forum is a combination of interested citizens and elected officials from 3 cities and Snohomish County. At steering committee meetings, management goals, priority target areas, and preferred control options were determined.
13 - What control methods were proposed in the IAVMP? And have these changed? Initial IAVMP herbicide approach was for use of only one herbicide (Fluridone). The IAVMP was modified to a more open-ended
11/14/2018 Page 2 of 3 WATER QUALITY AQUATIC INVASIVE PLANT FUNDING Organization: Mountlake Terrace city of WQAIP-2020-MouTer-00006 Aquatic Invasive Plant Project
approved herbicide approach, based on Ecology feedback on the draft IAVMP. Herbicide application will be supplemented by cutting and raking of invasive aquatic plants by volunteers, followed by the installation of bottom barriers (burlap sandbags). Herbicide application will be limited to 25% of the lake littoral zone annually, in order to reduce algal bloom potential.
14 - Is Public Education a part of this project? Yes
If yes, what means will you use to educate the public on the invasive plant issue that this waterbody is facing? A public education campaign is part of the control strategy, including public workshops on new herbicides, manual methods of control & decontamination, Forum meetings, info on the city website, Facebook/Twitter/Instagram, & other city publications.
15 - What are the overall goals for the waterbody? • Control and reduce invasive plant distribution and density • Keep swimming areas and boat launch areas clear of plants for optimal usability and safety • Improve habitat for fish and other aquatic species • Maintain beneficial uses: recreation/wildlife use/wq/water rights/downstream salmon protection • Eradicate small infestations of non-native invasive plant species • Prevent spread of non-native invasive plants (variable-leaf milfoil) from Hall Lake downstream to Lake Ballinger
16 - How does this project meet those goals? Goals will be met by controlling invasive species in areas where beneficial uses are currently impeded by excessive plant growth. Decreasing the quantity of invasive aquatic plants should increase the diversity of aquatic plants able to live in the lake, improving the aquatic habitat quality. Public education will also meet the above goals through educating lake users on how to prevent the spread of invasive species through manual weeding and use of boat/gear decontamination.
17 - Please list the decontamination measures you would implement to keep from spreading invasive species to other areas from your site and additional species into your site. We intend to follow the Ecology SOP EAP070, Version 2.2 "Minimize the Spread of Invasive Species" (March 2018), including the protocols to decontaminate boats, trailers, waders, and any other field equipment. Before leaving the site, all buckets, coolers, waders, boots, and any other equipment that can hold water will be drained. All boat axle and wheel wells, motor, propeller, anchor, ropes, waders, and paddles will be checked and any plant materials or mud removed.
18 - Please include a map of the project area along with documentation of the infestation size.
