The Hillsborough River is a 54-mile long river in western Florida that flows from the Green Swamp to Hillsborough Bay in Tampa. The river has a rich history, as it was home to Native American tribes and served as a major transportation route during the Spanish colonial era. The river is also known for its diverse hydrology, with shallow marshes, wetlands, and deep pools. The Hillsborough River is impounded by two major reservoirs, the Hillsborough River Reservoir and the Tampa Bypass Canal. These reservoirs provide flood control and water supply to the surrounding areas. The river is a popular recreational destination, with activities such as fishing, boating, and hiking available. The Hillsborough River also supports agriculture, with crops such as strawberries, blueberries, and citrus grown along its banks.
