ROBERTS LAKE ASSOCIATION: Roberts Lake 2026-2027 EWM Monitoring & Control Project

The Roberts Lake Association (RLA) is sponsoring a project to manage nuisance-causing EWM in the lake. The project will implement a spot treatment and follow-up manual removal efforts consistent with their 2025 APM Plan. This project would monitor the efficacy and native plant selectivity for two summers post treatment.

Activities: 1) EWM management (herbicide treatment and DASH/handpulling); 2) Point-intercept surveys; 3) Late season EWM mapping surveys; 4) Herbicide concentration monitoring and analysis.

Deliverables: 1) EWM management and permit reporting (herbicide treatment and mechanical harvest records); 2) Data from aquatic plant surveys; 3) Herbicide concentration monitoring results in SWIMS database; 4) Annual and final EWM management and monitoring reports.

Conditions: 1) All monitoring shall follow DNR protocols; 2) Conduct annual meeting with DNR 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.
