A tributary in Geauga County of the Chagrin River, and the Rocky River and its tributaries, located in Medina County, are the host to populations of wild Brook trout in Ohio. The Chagrin tributary is the only remaining naturally occurring population of native Brook Trout in Ohio. Both of these rivers are located in Northeast Ohio. State regulations prohibit possession of trout from these waters. For this reason it is advisable to use barbless hooks when fishing for trout in either of these two rivers but it is legal to harvest steelhead trout from these two rivers.
