The Flatrock River is a picturesque waterway that flows approximately 88 miles through east-central Indiana, originating in the rich farmland of Henry County before joining the Driftwood River to form the East Fork of White River at Columbus. Once lined with numerous water-powered mills that served early Hoosier settlers, the river now flows quietly through primarily agricultural landscapes, with a characteristic narrow wooded corridor following its course. Despite its name suggesting a rocky riverbed, Flatrock actually flows through some of Indiana's deepest and richest soils. The river offers a serene and tranquil setting for anglers, with diverse fish populations and beautiful natural surroundings making it one of the most beautiful smallmouth rivers in the state.
