Fishing Report

For lake updates and fishing information in the north central area contact the Clear Lake Fish and Wildlife office at 641-357-3517.
No reports this week.
Bluegill - Fair: Try with a slip bobber for the bluegills near the deeper dredged water (11-13'). Casting a lighter jig and letting it slowly sink will also catch some fish. Tip with a worm or leech.
Largemouth Bass - No Report: Try on the Dredge cut weedline or up close to the rock shorelines.
Walleye - No Report: An occasional walleye may be caught near the edge of the dredge cut along the edge of the curlyleaf.

Fishing Forecast

Bluegill and crappie angling has been excellent at Crystal Lake. Bluegills range in size from 7-8 inches with a few fish approaching 9 inches. Crappie are 8-10 inches with an occasional larger fish. Largemouth bass angling remains good with fish over 18 inches available. Quality northern pike and walleye will be a bonus catch when angling at Crystal Lake.(2014)
