A grey, even sky over the water, with the surface near flat as pressure builds. The productive water at Grassy Lake will be around the seam between weed and open water. A long productive spell runs the day. A careful, quiet approach will out-fish a busy one. The season of moving fish: stay mobile and watch for bait.

Grassy Lake is listed under Alger County, Michigan. It sits at 768 feet above sea level. The water covers some 192 acres, so pick a bank rather than trying to cover it all. Some 3.2 miles of bank gives room to move when the wind turns. Size puts it in the front rank of our Alger County list. Munising sits 13 miles from here and is the nearest stop. Manistique is 24 miles away, with Gladstone at 33 miles. The line between counties passes nearby, which can change who manages the water.
Without a survey to go on, judge depth from how the bank falls away. Where the bottom changes texture, fish gather; find that line. Bays and points beat straight shoreline every time on water like this. Reported across Alger County: yellow perch, rainbow smelt and northern pike. What holds for the county may not hold for this water. Read Grassy Lake for ten minutes before the first cast goes out.
The year swings from about 15°F in January to roughly 65°F in July. The year runs cold to warm and back, with clear transitions. The lid arrives early and lasts until roughly mid April. The season between ice runs from about mid April to early December. From the thaw to midsummer the fishing improves week by week. Keep it in mind when planning a trip to Grassy Lake.
Nothing on record says whether the bank is open or closed. No dam controls it, and the level follows the season. Grassy Lake Boat Launch provides a boat ramp about half a mile away. There is a campsite 0.9 miles from the water. A small crankbait along the drop and a worm in the thick stuff cover the bass. Some banks are open only from a marked point. Night access is frequently treated as a separate matter. McKeever Lake, 0.7 miles away, makes the obvious fallback. For Grassy Lake, the notice at the access point is the final word.
