The interior rivers all received some rainfall but some more than others. The Cedar and Shell Rock in Butler Co. remain in good condition and anglers are doing well. The Wapsi and Maquoketa Rivers remain a bit high and muddy yet. Trout streams remain in excellent condition, for further angling information contact the N.E. District Office at 563-927-3276.
Channel Catfish - Excellent: Stink baits have been the hot commodity for channel catfish on the Cedar River. Fish the top or upstream end of log jams for some great catfish action.
The Cedar River continues to improve. There have been excellent reports of anglers catching channel catfish, good reports of walleye and smallmouth bass and fair reports on northern pike in Butler County. The Cedar in Black Hawk Co. has had some fair reports reports on both flathead and channel catfish being caught.
Smallmouth Bass - Good: Try casting artificial baits along rocky shorelines for some good action.
Walleye - Good: A jig tipped with a half crawler and twister tail is a deadly combination this time of year.
Flathead Catfish - Fair: Fish the larger snags with live bait for some good flathead catfish action.

The Cedar River throughout this stretch offers excellent angling opportunities for walleye, smallmouth bass, channel catfish and occasional northern pike. Boat electrofishing catch rates for walleye run from 50-60 fish per hour which reflects abundant numbers of walleye in this stretch of river. There are numerous access points throughout this stretch of river. Navigation on this entire stretch of river is good for smaller flat or V-bottom boats with a smaller hp motor or canoe. A fall 2017 electrofishing survey on this area sampled roughly fifty walleye with thirty seven percent of them being equal to or greater than fifteen inches in length. Three of these fish sampled were greater than twenty seven inches in length.(2017)
