Salmon Research: Alexander Lake Elodea Eradication
The goal of this project is to expand and implement the original management plan to eradicate Elodea in Alexander Lake for the total ~500 acres. Because Elodea is expanding its distribution rapidly, it is critical that this work be completed with a sense of urgency to eliminate Alexander Lake from being a source of infestation to other Mat-Su waters and salmon resources. The objectives include treatment, surveying high-risk water bodies, and expanded outreach.
Timeline: Summer 2017
Project StatusAlexander Lake was treated May 18-19, 2017. There were signs of impact from last fall's treatment, though not as much as hoped. Elodea was found in adjacent Sucker Lake. Water samples showed low chemical concentrations therefore treatments were ineffective. Will continue to evaluate better ways to treat in dynamic systems like Alexander Lake such as smaller doses at higher frequencies and alternative methods of application.
