There are no reservoirs or dams on the river, but the flow is regulated by the Rainbow Springs Dam, which was built in the 1930s. The river is popular for recreational activities such as swimming, kayaking, and fishing. It also supports agriculture, with citrus groves and cattle farms surrounding the river. The Rainbow River is a unique natural wonder and an important part of Florida's ecosystem.
