Grass Lake in Calumet County: How and When to Fish It

• Overview

  Grass Lake belongs to Calumet County, Wisconsin. The water sits 801 feet up. Surface area runs to about 24 acres — small enough to read in one session. By elevation it sits in the lower part of our Wisconsin listings. Some 1.9 miles away sits Brillion, the nearest settlement. Then Hilbert, 5.2 miles, and Reedsville, 5.2 miles. Rules can differ a short way off, since the county line is near.

• Where to Fish on Grass Lake

  Depth went unrecorded, which puts the reading back on you. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Survey and observation records for Calumet County include common carp, rainbow trout, bluegill and pumpkinseed. The county figures include rivers and lakes alike. On Grass Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  The warmest month averages 70°F, the coldest about 16°F. The season turns properly here, and fish follow it closely. Break-up comes around early April, and the run that follows is short and strong. Break-up sits around early April on average, with the water closing again about early December. May into June fishes hardest, and September gives a second good stretch before the lid returns. Expect Grass Lake to follow that timing.

• Tackle & Baits

  Whether the bank is open is not something our records settle. A carry of half a mile from the nearest parking is the price of fishing here. There is a toilet block some half a mile out. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Sort the permit out before you load the car. Barbless rules turn up on managed water more often than not. For a change of water, Round Lake is 0.6 miles distant. Confirm before you fish Grass Lake.
