Bands of rain crossing through the day, with light air out of the ESE as pressure slides. Activity on Grass Lake should centre on bays that hold the day's warmth. If you must go, go in the night. One good spot fished well beats five fished quickly. Falling temperatures are switching fish back on.

In Minnesota, Grass Lake falls inside Itasca County. The surface lies 1,348 feet up. It runs to roughly 118 acres — big enough to hold fish away from the bank, small enough to learn. Around 2.6 miles of margin, front to back. The closest town, Cohasset, is 26 miles away. It is 154 miles to Fargo, the nearest city. The nearest edge is a long way off, so local rules apply throughout.
Depth is not on record here, which means reading the ground instead. Look for the band where the shallows give up and the bottom falls away. Still water like this holds fish on the edges rather than out in the open. Reported across Itasca County: yellow perch, largemouth bass, northern pike and bluegill. County data is a starting point rather than a guarantee. Grass Lake gives up more to patience than to distance.
Climate records put July near 67°F and January near 4°F. Hard water is a season in its own right here. Winter locks it down, and mid April brings it back. Ice usually gives way near mid April, and forms again about late November. Reckon on open water from spring through to late autumn, with May and June the strongest. That is the shape of the year on Grass Lake.
Our records carry no access rule either way. Records list it as a natural water body rather than an impoundment. No car park, ramp or path is recorded within easy reach of the shore. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Check locally before you travel, because a wasted drive is a long one. Some ground is open by custom rather than by right, so tread carefully. The nearest alternative is Maple Lake, 0.9 miles out. Nothing here settles the position at Grass Lake for certain.
