About the Kokosing River
The Kokosing is one of Ohio’s designated State Scenic Rivers and it earns the label. It runs west to east across Knox County through Mount Vernon and past Gambier before joining the Mohican to form the Walhonding, and along most of that distance it is exactly what a Midwestern smallmouth stream should be: clear, gravel and cobble bottomed, shaded by sycamores, with working riffles separating long pools and enough gradient to keep the water moving through the summer. It is also easy to float. The Kokosing Gap Trail follows a good stretch of it, access is reasonable, and the river is shallow and forgiving enough for anglers who are new to moving water.
Smallmouth bass are the main event and the river holds them in good numbers, on the rock, in the riffle tailouts and tight against the log jams on the outside bends. Rock bass are abundant and aggressive. Longear sunfish are unusually common here and are worth catching in their own right for the color alone. Channel catfish use the deeper pools throughout, flatheads hold in the biggest holes on the lower river, and largemouth and crappie occupy the slower backwaters and the mouths of the tributaries. The lower reaches below Howard get bigger and slower as the river approaches the Walhonding, and the fishery shifts toward catfish accordingly.
The Mount Vernon gauge publishes discharge and stage without a temperature sensor. Discharge is the planning number: the Kokosing is a modest river that runs thin by late summer, so a float that is comfortable in June turns into a walk in August, while a spike after rain will color it up for a day or two. The most pleasant conditions are the moderate, stable flows of early summer and early fall.
