Green Lake Integrated Aquatic Vegetation Management Plan Development

Fall 2024

Thank you to everyone who joined us at our meeting on November 20! 

In 2021, SPR coordinated an aquatic plant survey with an environmental consultant and aquatic plant specialists from King County and the Washington Department of Ecology (Ecology). This survey found Brazilian elodea throughout most of the central portion of the lake and milfoil along most of the nearshore region indicating an expansion much larger than was measured in 2005.  

Based on the survey results, the environmental consultant recommended the development of an integrated aquatic vegetation management plan (IAVMP) following Washington Department of Ecology guidelines. The IAVMP will define aquatic plant management goals on Green Lake based on input from the public and the steering committee. The IAVMP will also include an evaluation of plant management techniques and the development of an adaptive management approach. The IAVMP will incorporate input from the steering committee and the public received via three steering committee meetings and two public meetings. 
 
The steering committee is comprised of King County and Washington state agency representatives local stakeholder groups and recreation users of Green Lake. Multiple control strategies will be presented and discussed with the steering committee, and ultimately, the steering committee will agree on one control strategy. Following the development of a Draft IAVMP, the plan may be used to apply for grant funds from the Washington Department of Ecology’s Aquatic Invasive Plant Management Grant Program.
