Project final deliverables include: a whitepaper research report, and excel spreadsheets containing all data collected for the study.

Specific project activities include: 1) Measurement of sediment plumes caused by boat wakes; 2) Collection of water clarity and dissolved oxygen at 6 sites twice a week in the summer of 2021; 3) Collection of TSS and Total Phosphorus samples twice a week from May through September and 4) aquatic plant sampling.

Special Conditions: 1) All data shall be entered into the SWIMS database; 2) Grantee shall use the Wisconsin State Lab of Hygeine for water sample analyses.

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.
