The Whitewater River is a 30-mile-long tributary of the Little Miami River in southwestern Ohio. It is a popular destination for whitewater kayaking and canoeing due to its fast-moving rapids and scenic beauty. The river's name is believed to have originated from the white foam created by the rapids. The river's hydrology is primarily influenced by rainfall and snowmelt. The river flows through several reservoirs, including East Fork Lake and William H. Harsha Lake, which are used for flood control, water supply, and recreational purposes. The river's water is also used for agricultural purposes such as irrigation. The river has a rich history, having played a crucial role in the development of the region's early industries, including mills and factories. Today, the Whitewater River is a popular recreational destination enjoyed by many outdoor enthusiasts.
