Sangamon River Fishing Guides
The Sangamon runs past Lincoln's New Salem on its way to the Illinois River, a prairie smallmouth and catfish stream with more history on its banks than almost any water in the state.

About the Sangamon River
The Sangamon is the river Abraham Lincoln arrived on. New Salem, the reconstructed village where he spent his early twenties, sits directly above the gauge at Petersburg, and the river Lincoln famously got a flatboat stuck on is the same water anglers float today. That history gives the Sangamon a standing in central Illinois that its size alone would not, but the fishing holds up on its own terms. This is a classic prairie river: wide, brown, slow through the pools and lively over the gravel bars, with smallmouth bass on the hard bottom and catfish everywhere else.
Through the Petersburg reach the river has cut down into the glacial till far enough to expose gravel and occasional rock, and that is where the smallmouth concentrate. They are rarely large by northern standards but they are abundant and willing, and a day of wading the riffles with small crankbaits or tubes is a genuinely good way to spend it. The pools between the bars hold channel catfish and flathead catfish, with drum, carp and gar common and crappie stacking up around the deeper wood. Walleye appear in modest numbers, mostly in the lower reaches toward the Illinois River.
Flow is the thing to watch and the thing that frustrates. The Sangamon drains a very large, heavily tiled agricultural basin above Petersburg, including Lake Decatur, and it rises and falls fast. The gauge record through a dry autumn sits in a narrow low band; after a summer storm the river can go from wadeable to unfishable overnight and stay turbid for days. Late summer through October is the dependable window, when the water drops clear enough to read the bars and a canoe can cover the long quiet pools between them.

Petersburg - the gauge town and the usual access point, with bridge and park frontage on the middle river.
Lincoln's New Salem State Historic Site - state land immediately upstream with parking, trails and walk-in river access.
Sangamon River Valley at Oakford - a downstream community useful for reaching the lower reach.
Salt Creek confluence - the major tributary mouth downstream, where the river gains size.
Jim Edgar Panther Creek State Fish and Wildlife Area - large public land holding in the lower valley.
Athens - an upstream town with road-crossing access to the smaller water above Petersburg.
Illinois River confluence near Beardstown - the downstream end, where the Sangamon enters the Illinois.
Seasons
Spring: high, cold and turbid off the prairie, with catfish the realistic target until the river drops in late May.
Summer: smallmouth season on the gravel bars, with wadeable water between storms and catfish active through the warm nights.
Fall: the best conditions of the year, low and clear enough to read the bars, with smallmouth feeding hard into October.
Winter: cold and slow, with the deep pools and the Salt Creek confluence the most consistent water.
