Aquatechnex biologists will be starting this year’s aquatic plant management work with a detailed survey of Loon Lake the first week in June. This effort will involve hydro-acoustic mapping of the plant beds and a detailed examination of the plant community species make up. Loon Lake has seen infestations of Eurasian and Hybrid forms of milfoil and Curly Leaf Pondweed. Both species are detrimental to the health of the lake and beneficial uses.
Hybrid milfoil poses the major problem in the lake at the end of 2018. The Loon Lake LMD through Stevens County have received a grant to develop treatment strategies to confront this problem plant. This involved the collection of plants from the lake, DNA testing to determine hybrid strain, shipping plants to the Aquatic Plant Control Research Program at North Carolina State University and subjecting them to a concentration exposure time study with a number of herbicides. We will be using this information to start operational control work this summer.
The new herbicide Procellacor performed very well in these laboratory experiments and will be used in Loon Lake soon after it is approve for addition to the Washington State Department of Ecology permit in early July. This technology should provide long term control in Loon Lake.
We will update this with maps of the treatment areas as the survey is completed. If you have any questions please address them to firstname.lastname@example.org.
