Indiana Smallmouth bass 2026 — Season, Bag Limit, Size Rules
Micropterus dolomieu
Last updated
Indiana's smallmouth fishery is anchored by the Sugar Creek (Parke + Montgomery Counties — Indiana's most-celebrated wild smallmouth stream, 110+ miles of free-flowing rocky-bottom water through Turkey Run + Shades State Parks) and the Tippecanoe River (228 miles, north-central Indiana — one of the country's premier wild smallmouth bass streams). The East Fork White River + West Fork White River + Big Blue River + Driftwood + Flatrock + Wildcat Creek + Salt Creek round out the stream smallmouth tier. On the reservoir side, Patoka Lake + Lake Monroe + Brookville Lake hold strong smallmouth populations on the rocky shoreline structure. The Ohio River boundary water with Kentucky (660 miles, 14 reciprocal compact counties) holds river smallmouth + walleye + striped bass + flathead. The Wabash River boundary with Illinois (200+ miles) carries the western-IN stream smallmouth. Indiana's rule splits by water type: rivers + streams (where most smallmouth live) run a 12-to-15-inch protected slot — release all bass 12–15 inches, keep no more than two over 15 inches — within a 5-fish combined black-bass aggregate; lakes + reservoirs carry a flat 14-inch minimum. A flat 12-inch minimum applies in the 13 Ohio-River-border counties and on the Ohio River main stem (6 / day); Lake Michigan runs 14-inch / 3-per-day. Patoka Lake runs a 15-inch reservoir minimum; Sugar Creek + Turtle Creek Reservoir carry a 20-inch minimum + 1-fish daily limit (functionally trophy catch-and-release).
