Mist hanging over the margins today, with a busy SE wind on the open water and the barometer heading up. Give the first drop-off and weed lines the first hour at Grass Lake. The forecast is against you; the middle of the day is the least bad option. Short, focused sessions beat a long grind today.

Grass Lake is an Otter Tail County water, in Minnesota. The ground round it is mixed forest. The water covers some 81 acres, so pick a bank rather than trying to cover it all. There is roughly 1.6 miles of shoreline here, which is a short walk end to end. New York Mills lies 10 miles from the water. Further out sit Perham (13 miles) and Wadena (18 miles). The nearest boundary is well away, so one set of rules covers the water.
Depth is unknown to us, and the shoreline is the better guide. A natural lake fishes on cover, and cover here means weed and timber. Still water like this holds fish on the edges rather than out in the open. County-wide records name largemouth bass, black crappie, walleye and bluegill. Those are county-wide records, so not every one of them will be in this water. The near bank of Grass Lake is often the one people ignore.
The warm month here averages 70°F; the cold one sits at 6°F. Winter closes the water for a while, and the reopening is worth catching. The freeze runs deep into the year, with break-up near mid April. Averages suggest open water from about mid April through to roughly late November. The first weeks of open water and the last are the ones to plan for. Plan around that when you fish Grass Lake.
Nothing on record says whether the bank is open or closed. No dam controls it, and the level follows the season. Nothing formal is recorded here: no ramp, no car park, no marked path. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Parking is often the real limit rather than the bank itself. Access can change hands, so last year's answer may not hold. Portage Lake, 1.1 miles away, makes the obvious fallback. Confirm before you fish Grass Lake.
