Fishing Regulations Relaxed at Black Hawk Lake Ahead of Renovation
Posted: 09/19/2012
LAKE VIEW – Beginning Sept. 22, the Iowa Department of Natural Resources will relax the fishing regulations at Black Hawk Lake, in Sac County, to allow anglers to harvest fish before the fish population is renovated as part of a lake improvement project.

Until further notice, anglers with a valid fishing license may take fish by any means except dynamite, poison, electroshocking devices, or any stupefying substances.  In addition, daily bag and minimum length restrictions are lifted.  Taking fish for commercial purposes is not allowed. 

Black Hawk Lake is suffering from poor water quality and a high population of rough fish, including common carp, that contribute to the deteriorating condition of the lake. The low water levels brought on by the drought provided an opportunity to renovate the lake by eliminating the rough fish. 

A second stage of the lake improvement is reducing runoff and nutrients from entering the lake from the watershed. When completed, the project will provide healthier fish and wildlife habitat, but the overall goal is clean water.

The lake will be restocked with a balanced fish population of walleye, bluegill, largemouth bass, channel catfish, black crappie, yellow perch and muskellunge. The fish should grow rapidly in the new lake environment, including some reaching angler acceptable size within 2 to 4 years of stocking.

Black Hawk Lake should show an increase in water quality and clarity and lake users should expect to see submergent vegetation. Anglers should expect more consistent quality sport fishing in the coming years and lake users should expect to see fewer algae blooms.

The promiscuous fishing designation allows anglers to salvage and utilize imperiled fish populations.
