The Detroit watershed, located in northern Michigan, covers an area of approximately 3,900 square miles. The watershed is characterized by its diverse hydrology, including forests, wetlands, rivers, and lakes. The region receives a significant amount of snowfall, with snowpack accumulation up to several feet in some areas during the winter months. The snowmelt from this snowpack is a crucial source of surface water for the streams and rivers in the watershed. The reservoirs in the Detroit watershed are primarily used for water supply and hydroelectric power generation. Interesting climatic facts and trends include the increased frequency of intense precipitation events in recent years, which have led to more frequent flooding and erosion. There has also been a trend towards earlier snowmelt and reduced snowpack in the spring, which has implications for water availability and timing of stream flows.
