History & Status of the Fishery
The fish population in Lake Decatur is intensively surveyed every two years. The fish are measured, weighed, and scales collected before releasing them alive. Hybrid striped bass and walleye populations are surveyed annually and are maintained by annual stockings through IDNR hatcheries.

Buffalo, Redhorse suckers, and Carpsuckers are common, but few are caught by fishermen.
Yellow bass, Longear sunfish, Green sunfish, Orangespotted sunfish, and Yellow bullheads are collected, but are seldom harvested by fishermen due to the small size attained by these species.
Smallmouth bass, Rock bass, and Redear sunfish are very rarely collected and are likely very rare in the anglers catch.

Man how this lake has come up in the world of fishing over the past 30 or so years. Back when I lived in and around Decatur this lake was hardly more than a big mudhole. One might catch a few channel cats from time to time and even a bass now and then in the upper part of the lake or up some of the feeder streams. I remember fishing it because it was about the only place to fish around but seldom did we have much success. The one exception being in early summer when there would be a frog strangler rain. The creeks would be out of banks for a few hours and the channel cats flocked up to feed. Several such times found us wading out to the creek channel edge on Findley creek or Big creek to catch a bunch of challel cats. At certain times in the early spring crappie could be caught but I was never there at the right time. Now I see the lake has walleye, muskie, and a whole list of fish. I believe the lake has been cleaned up too since I was there. I would have to rate it only one star from when I fished it but maybe it would rate several more stars now.
