COURTE OREILLES LAKE ASSOC.: 2023 Lac Courte Oreilles/Little Lac Courte Oreilles AIS Large Scale Population Management

Courte Oreilles Lake Association is sponsoring a project to implement approved Eurasian watermilfoil and curly-leaf pondweed control activities from their aquatic plant management plan.

Project final deliverables include:

1) EWM and CLP management and required permit reporting (DASH, mechanical, and herbicide treatment records);

2) Data from PI survey, bed mapping surveys, sub-PI survey, and public/volunteer AIS reporting/monitoring;

3) Herbicide concentration results in SWIMS;

4) Annual progress and final reports.

Specific project activities include:

1) AIS control with a variety of management techniques;

2) Public AIS location reporting, volunteer plant identification training, volunteer AIS monitoring, and GIS mapping of AIS locations;

3) Aquatic plant point-intercept (PI) survey;

4) Annual EWM and CLP bed mapping surveys;

5) Sub-PI survey of CLP harvest areas;

6) Herbicide concentration monitoring and analysis;

7) Annual progress and final reports summarizing AIS management and monitoring during project and future management direction.

Special Conditions: DNR is to receive copies of a final report along with, or prior to submission of grantee's final payment request. It is recommended that Grantee provide DNR Lake Coordinator with a draft of the final report for comment on report adequacy prior to making final payments.

The whole-lake aquatic plant PI survey should not be conducted in a year when large-scale herbicide treatments are taking place.

It is strongly recommended that an annual management strategy meeting be held each winter with DNR to discuss AIS management for the next year before aquatic plant management permit applications are submitted.

This scope summarizes the project detail provided in the application and does not negate tasks/deliverables described therein. Data, records, and reports, including GIS-based maps, and digital images, must be submitted to the Department in a format specified by the regional Lake Biologist.
