The Mississippi River Watershed is a vast area of land that collects rainwater and snowmelt, directing it into the Mississippi River and its tributaries. This watershed spans parts of 32 U.S. states and two Canadian provinces, covering approximately 1.2 million square miles. It plays a crucial role in the region's ecology and economy, supporting diverse wildlife and agriculture. The watershed is divided into several smaller basins, including the Ohio River Basin and the Missouri River Basin. These areas contribute to the overall flow of the Mississippi River, which eventually empties into the Gulf of Mexico. The health of the watershed is vital for maintaining water quality and managing flood risks.
