The Twin Cities Watershed, located in Minnesota, covers 1,008 square miles of land and is part of the Mississippi River Basin. It is characterized by a humid continental climate, with cold winters and warm summers. Hydrologically, the watershed is dominated by the Mississippi River and its tributaries. Snowpack plays a crucial role in the watershed's water supply, and the average annual snowfall is around 54 inches. The watershed contains several reservoirs, including the Minneapolis Chain of Lakes and Lake Minnetonka, which are used for recreation, water supply, and flood control. Surface water quality in the watershed is affected by urbanization, agriculture, and industrial activity. Over the past few decades, the watershed has experienced an increase in extreme weather events, including heavy precipitation and flooding. Efforts are underway to manage these impacts and protect the watershed's resources.
