Michigan is characterized by a temperate climate, and the state is home to several major surface flows, including the Great Lakes and their tributaries, the Grand River, St. Clair River, and Detroit River. The state has over 1,000 dams and reservoirs, with the largest being the 5,000-acre Houghton Lake. Michigan has a diverse hydrology, with wetland systems, streams, and inland lakes contributing to the water cycle. The state's snowpack is a significant contributor to hydrology, with winter snowfall providing a significant portion of the water supply for the Great Lakes and their tributaries. Additionally, the state is prone to flooding due to its topography and geographic location, and heavy rainfall events can result in flash flooding and riverine flooding.
