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

• Overview

  Grass Lake stands in Marinette County, Wisconsin. This is mixed forest country. The water covers some 79 acres, so pick a bank rather than trying to cover it all. With about 1.4 miles of edge, you can try several depths in one session. It ranks high for size among our Marinette County listings. Some 25 miles away sits Gillett, the nearest settlement. It is 51 miles to Green Bay, the nearest city. It lies deep inside the county rather than near an edge.

• Where to Fish on Grass Lake

  Depth is unknown to us, and the shoreline is the better guide. This is a lake, so the margins and the first drop matter most. A natural lake fishes on cover, and cover here means weed and timber. County-wide records name brown trout, rainbow trout, largemouth bass and bluegill. The list covers the county rather than this water alone, so treat it as a guide. On Grass Lake the first feature you find is usually worth a session.

• Seasonal Patterns

  Long-term averages put July at about 68°F and January near 13°F. A solid cap is the normal state through winter. Break-up comes around mid April, and the run that follows is short and strong. From about mid April to around early December, expect open water on the long-run figures. The weeks after the thaw and the ones before the freeze are the strongest. It holds true on Grass Lake more years than not.

• Tackle & Baits

  Access is not recorded for this water. It formed naturally, so levels move with rainfall rather than with a gate. Mapping is blank for access, so scout the approach before committing the car. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Rules differ from one water to the next round here. Access can change hands, so last year's answer may not hold. For a change of water, Eagle Lake is 1.3 miles distant. Check the position on Grass Lake before loading the car.
