The Iowa DNR has posted these fishing reports this week:

Cedar River (above Nashua)The Cedar River continues to drop and water clarity is improving. Use this opportunity to get out and play before the cold weather sets in. Walleye – Good: Use a jig tipped with a long piece of worm or minnow in deeper pools and around brush piles near evening. 
Cedar River (Nashua to La Porte City)

There have been good to excellent reports of anglers catching walleye, northern pike and smallmouth bass on the Cedar River. Target deeper pools or holes for walleye as they migrate to overwintering areas. Walleye – Good: Use jigs tipped with plastics with or without live bait. Northern Pike – Good: Cast white bucktail spinner baits. Smallmouth Bass – Good: Try jigs tipped with plastics with or without live bait or spinner baits.
