This plan outlines the large research and planning effort to address chronic water quality issues in four lakes known collectively as the CalMan lakes; Long Lake in Manitowoc County and Round, Boot, and Becker lakes in Calumet County. These four lakes are in the same drainage system with Round and Boot lakes being headwater lakes which drain to Long Lake; and Long Lake then drains into downstream Becker Lake. Becker Lake is drained via an unnamed tributary to Spring Creek which ultimately flows into the Manitowoc River. This study set out to determine nutrient load budgets for all four lakes and develop a Nine Key Element Plan (9KE) to address the excessive nutrient levels and remove each lake from the Wisconsin impaired waters list.

Calumet and Manitowoc County lakes final WMP.

Calumet County proposes to quantify and compartmentalize nutrient budgets for the four lakes situated along the Calumet/Manitowoc County boarder which includes Round, Becker, Boot, and Long Lakes through in-lake, tributary, groundwater and watershed monitoring and modeling. Specifically, Phase 3 will include: 1. In-lake baseline water quality monitoring of the four lakes. 2. In-lake phosphorus profiles and sediment-water interface samples. 3. Sediment core samples and analysis from each lake. 4. Tributary flow, phosphorus and suspended solids load monitoring. 5. Shallow groundwater monitoring using mini-piezometers. 6. Watershed modeling for nutrient budget utilizing EVAAL and FLUX. 7. Precipitation monitoring within the watershed. 8. Watershed stakeholder and planning committee meetings. 9. Stakeholder survey and Agricultural producers interviews. 10. Final report summarizing the results as well as an implementation plan for this watershed and these lakes.
