TWA Report for the Lake Weyauwega subwatershed of the Waupaca Tomorrow River Watershed.

The Weyauwega Lake-Waupaca River Watershed is a subwatershed of the Wolf River Basin in Wisconsin and is located in southern Waupaca County. The watershed drains a total area of 20,742 acres with City of Waupaca on the west side and City of Weyauwega on the east end. Waters in the Wolf River Basin are impaired due to excess phosphorus and total suspended solids. The Federal Clean Water Act requires states and authorized tribes to identify and restore impaired water bodies. A draft Total Maximum Daily Load (TMDL) plan has been developed for the Upper Fox and Wolf Basins to identify the sources of pollutants and the reductions necessary to address water quality impairments. The development of implementation plans for the subwatersheds of the Upper Fox and Wolf River Basin are necessary to meet the assigned daily loads of the TMDL. The Weyauwega Lake-Waupaca River Watershed plan provides a framework to accomplish the following goals: Goal #1: Improve surface water quality to achieve Wisconsin Department of Natural Resources/Environmental Protection Agency water quality standards. Goal #2: Increase citizens awareness of water quality issues and active participation in stewardship of the watershed. Goal #3: Reduce runoff volume and flood levels during peak storm events. Goal #4: Conserve and restore aquatic and terrestrial habitat.

The monitoring in 2017 indicate water quality in the tributaries of the Lake Weyauwega sub-watershed ranges from poor to excellent. Some of the land use characteristics observed during the 2017 monitoring project that can have a negative impact to the water quality of the tributaries to the Waupaca River were limited buffer protection along the stream corridors, wetland ditching, eroding stream banks, cropland erosion, channelization, cattle access, tile drainage, presence of aquatic invasive species, and sedimentation of fish and aquatic life habitat There are opportunities to install practices to lower the nutrients and sediment reaching the Waupaca River and Lake Weyauwega. Continuing efforts to work with landowners, farmers, municipalities, the county and Natural Resource Conservation Service staff to promote protection and restoration of the streams and wetlands by practices including, but not limited to, streambank and buffer protection, cover crops, nutrient management planning, reduced tillage, wetland protection and restoration, and water and sediment control basins
