Fishing Report

Ice conditions remain good across most Black Hawk County area lakes but always take precautions when venturing onto ice. Fishing activity continues to be slow on area lakes. Anglers just need to get out and try different areas. For more information call the Manchester District Office at 563-927-3276.
Reports have been slow on Martens Lake. Anglers have been driving off of the boat ramp onto the lake as of 2/26/15. Access is also available from the northwest corner by walking across the reservoir and over the dike.
Bluegill - Fair: A jig tipped with a waxworm has been best. Sight fishing is generally best if water is clear.
Crappie - Fair: A jig tipped with a waxworm or crappie minnow is best. Sight fishing is generally best if water is clear.

Fishing Forecast

Martens Lake in Sweet Marsh is a consistent producer of quality-sized largemouth bass and provides good opportunities for bluegill and crappie. Martens Lake has abundant vegetation during summer months so many anglers prefer fishing for panfish during winter and early spring.(2014)
