Interior rivers are low and providing some fair to good angling opportunities for smallmouth bass, walleye and crappie. Rivers should be in good condition for the upcoming weekend. Lakes are beginning to produce some crappie. Trout streams are in excellent condition and providing some insect hatches with the warmer weather. For further information contact your area bait and tackle shops. All field stations and fish hatcheries remain closed at this time, for further information contact the N.E. D
Anglers are doing poorly on walleyes with little success but doing well on smallmouth bass on the Cedar River.
Smallmouth Bass - Good: Try jig and minnow or retrieving spinner baits for some smallmouth bass action.
Walleye - Fair: Cast and retrieve jig and plastics tipped with or without a minnow. Concentrate on pools and current breaks for some walleye action.
Channel Catfish - Fair: Anglers are having success using dead minnows, crawlers or cutbaits for catfish on the river now.
Black Crappie - Fair: Crappie are biting in the warmer backwater shallows, fish a minnow under a bobber near brush piles.

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 are good providing abundant numbers of walleye in this stretch of river. There are many access points throughout this stretch of river. Navigation on this entire stretch is good for smaller flat or V-bottom boats with a smaller hp motor or canoe. A fall 2020 electrofishing survey in Bremer County sampled 26 walleye with 64 percent of them equal to or greater than 15 inches long. Three of these fish sampled were greater than 25 inches long with one being 30.3 inches in length. Another fall 2020 electrofishing survey above LaPorte City provided good numbers of channel catfish with decent numbers of walleye, smallmouth bass and shovelnose sturgeon.(2020)
