Au Gres-Rifle
Watershed Hydrology
The Au Gres Rifle Watershed spans approximately 370 square miles in Michigan, and is part of the larger Saginaw Bay watershed. The area is characterized by rolling terrain and a mix of agricultural and forested land use. The watershed is home to several lakes and streams, including the Rifle River, which supports a variety of fish species. The watershed also has several reservoirs, including the Secord, Smallwood, and Sanford dams. The climate in the Au Gres Rifle Watershed is classified as humid continental, with cold winters and warm summers. The area receives an average of 35 inches of precipitation per year, with snowfall typically occurring from November to March. Snowpack plays an important role in the hydrology of the watershed, as it helps to replenish surface water and groundwater supplies during the spring melt. Water quality in the watershed has been a concern due to agricultural runoff and other sources of pollution, but efforts are underway to improve conditions. The Michigan Department of Environmental Quality has identified several impaired water bodies in the watershed, and is working with local stakeholders to develop management plans to address the issues.
