Summary

Description of Work U.S. Geological Survey (USGS) scientists will assess the hydrology, water quality, and response to simulated changes in phosphorus loading of the Winnebago Pool Lakes, Wisconsin. Total annual phosphorus and total suspended sediment loads will be estimated at various monitored locations throughout the Upper Fox and Wolf River Watershed using a rating curve method or GCLAS with streamflow monitored by the USGS and water quality data collected by the Wisconsin DNR. Monitoring at three new sites was done as part of this study. Data from these three sites will be used to help calibrate the SWAT model for the basin. These loads will be supplied to the Cadmus Group, Inc. to help calibrate SWAT models for the Basin. A detailed [...]

Purpose

The purpose of the project is to: 1. Document the present and historical water quality of each of the Winnebago Pool Lakes (Poygan, Winneconne, Butte des Morts, and Winnebago); 2.Estimate total annual phosphorus and total suspended sediment loads at various monitored locations throughout the Upper Fox and Wolf River Watershed; 3. Determine a detailed phosphorus budget for each of the Pool Lakes that quantifies the sources of phosphorus to each lake; 4. Use calibrated eutrophication models to simulate the likely response in phosphorus, chlorophyll a, and Secchi depth of each of the Winnebago Pool Lakes to changes in phosphorus loading associated with various lake-management actions that might be implemented to improve water quality, and understand how these actions may affect the nutrient loading to the Lower Fox River and Green Bay; 5. Provide information (Final Report) to construct a TMDL for the Upper Fox/Wolf River Watershed and the Winnebago Pool Lakes, and provide information for updating the Lower Fox and Green Bay TMDL.
