The Coon Pickerel watershed (HUC 11030004) is located in north-central Wisconsin and covers approximately 218 square miles. The area is characterized by numerous small streams that flow into the Wisconsin River. The hydrology of the watershed is heavily influenced by the region's glacial history, which has created a complex network of wetlands, lakes, and streams. In terms of climate, the Coon Pickerel watershed experiences a typical northern Midwest climate, with cold winters and warm summers. The area receives an average of 50 inches of precipitation per year, with much of this falling as snow during the winter months. The snowpack can be a critical source of runoff during the spring thaw, which can contribute to flooding in downstream areas. Surface water in the watershed is primarily held in small lakes and ponds, with some larger reservoirs also present. These reservoirs are used for a variety of purposes, including hydroelectric power generation and recreation. Water quality in the watershed is generally good, with low levels of pollutants and a diverse range of aquatic species present.
