In 1931 the Ohio Department of Natural Resources (ODNR) Division of Wildlife took control of the Rainbow trout project.
The minimum size required to keep trout caught on the Mad River is 12 inches, and the daily catch limit is two fish.
[3] The Clear Fork River is located near the town of Loudonville, OH, about one hour north of the city of Columbus, OH.
The Upper branch has limited accessibility and runs from the Clear Fork Reservoir East to Pleasant Hill Lake.
The stream has a great annual hatch of mayflies, including sulphers[check spelling], light cahills, drakes, and many caddisflies, as well.
The downfall is that in the late spring and summer months many other visitors are attracted to the stream such as rafters, tubers, and swimmers, which can negatively affect fishing as the water becomes too disturbed.
note=most of the swimmers, tubers, and rafters use the state park camping area for this activity, the best trout fishing for large browns is upstream from the covered bridge.
