Flatrock River
The Flatrock River is a major waterway in central Indiana, stretching for 60 miles from Henry County to Bartholomew County. It has a rich history, with Native American tribes and European settlers using it for transportation and fishing. Today, the river is primarily used for recreational activities like kayaking, fishing, and camping. The river is also an important source of water for agriculture in the area. There are several dams and reservoirs along the river, including the Cataract Dam, which was erected in 1927 to provide hydroelectric power to nearby communities. In recent years, there has been concern about water quality in the Flatrock River due to agricultural runoff and other pollution sources. Efforts are underway to protect the river and ensure it remains a valuable resource for generations to come.
