About the Great Miami River

The Great Miami runs from Indian Lake in west-central Ohio down through Dayton and Hamilton to the Ohio River, and it is a much better fishery than a river flowing through two industrial cities has any right to be. Water quality improved substantially over the past several decades, and the low-head dam removals through the Dayton and Hamilton reaches restored current and connectivity that the river had not had in a century.

Smallmouth bass are the headline species and the river produces them consistently through the riffle and run sections, particularly in the reaches between the cities where gravel and limestone ledges dominate. Hybrid striped bass are the surprise – stocked into the system and running the river in schools that can produce genuinely hard fighting fish on light tackle below the dams and in the deeper pools. Sauger and saugeye hold in the current below structure and fish best in the cold months, white bass run in spring, and channel and flathead catfish are abundant with flatheads reaching serious size in the log jams. Spotted bass, freshwater drum and longnose gar round out a broad list.

Access is excellent and that is the real selling point. Dayton and Hamilton have both invested in riverfront parks and paddling infrastructure, there are formal launches and river access points the length of the corridor, and the Great Miami River Recreational Trail follows much of the bank. Wading works well at summer flow on the gravel reaches; a kayak covers considerably more water.

It is still an urban river. Flows spike quickly after rain, clarity drops with them, and there are fish consumption advisories on parts of the system worth reading before you keep anything.
