Most Black Hawk County area lakes have been inundated with flood waters and remain high and turbid. Trout streams have fallen and are in excellent condition now, for further angling information contact the N.E. District Office at 563-927-3276.
The Maquoketa River received a fair amount of rainfall this past week but is falling quickly and clearing up well.

The Maquoketa River offers great paddling and angling opportunities throughout this seventy mile stretch. Very good smallmouth bass fishing occurs in many areas of this river due to all of the suitable rocky habitat. Concentrate efforts near these areas in which "smallmouth " love! Note, there is a Catch & Release Area for all bass in Delaware County extending downstream for four and a half miles from below Lake Delhi Dam as posted to the first county gravel road bridge, Pioneer Road. A strong population of channel catfish, existing from Manchester downstream will provide great fishing opportunities for anglers of all ages. It's not uncommon for an angler to catch a "memorable" northern pike in this stretch. Pike densities are low but sustained with additional DNR stockings in early spring (see fish stocking tab above for more info). This stretch of river is most accessible by means of a kayak or canoe as the river is fairly wide and shallow in places. Ten access points, mostly carry-down, provide paddlers and anglers many options throughout this entire scenic area of river. Be sure to stop and visit the newly constructed/dam removal project, "Manchester Whitewater Park," truely a must see for all outdoor enthusiasts! Voyage a ride down through the six drop structures or simply enjoy the view from the beautiful landscaped park. Fish habitat and passage were also designed into the new park adding exceptional habitat for smallmouth bass and walleye. A hard surface boat ramp located at Bailey's Ford County Park, Delaware County, provides boat anglers access to a popular overwinter staging area for walleye. Kayak and canoe rentals are available in the city of Manchester. Check the local directory for phone numbers and rental availability.(2017)
