ARBUTUS LAKE ASSOCIATION: Arbutus Lake 2025-2026 EWM Monitoring & Control Project

The Arbutus Lake Association is sponsoring a project to implement an integrated pest management strategy for EWM management including a whole-lake herbicide treatment in Arbutus Lake in 2025 with follow up hand harvesting in 2026.

Activities: 1) Pretreatment EWM refinement survey; 2) EWM management (herbicide treatment and hand pulling); 3) Annual late summer EWM bed mapping; 4) Point-intercept surveys; 5) Herbicide concentration monitoring and analysis.

Deliverables: 1) Pretreatment survey report including temperature profile data collected; 2) EWM management and permit reporting (herbicide treatment records); 3) Data from all aquatic plant surveys; 4) Herbicide concentration results in SWIMS database; 5) Annual and final EWM management and monitoring reports.

Conditions: 1) All monitoring shall follow DNR protocols. 2) Conduct annual meetings with DNR Biologist to discuss EWM management for the next year before aquatic plant management permit applications are submitted.

This scope summarizes details provided in the application and does not negate tasks and/or deliverables described therein. Data, reports, surveys, and supporting information, including photos, maps and GIS data, must be submitted to the DNR Biologist in electronic format and in any other format they specify.

If a consultant provides a final report, it is recommended that the Grantee provide the DNR Biologist with a draft for comment on report adequacy prior to making a final payment to the consultant. Include electronic copy of the final report along with or prior to submission of grantee's final payment request.
