An even grey lid over the water, with a mirror surface most of the day and steady pressure. Most of the action on Rumble Lake should come off sheltered bays and points. Expect the better fishing from the day. Work fewer spots, but work them properly. Shortening days concentrate the feeding into fewer hours.

You will find Rumble Lake in Schoolcraft County, Michigan. What surrounds it is mixed forest. Small at around 18 acres: two anglers spread out cover most of it. You are 16 miles from Munising. Manistique follows at 22 miles, then Gladstone at 32 miles. Within easy reach: Sprinkler Lake roughly 0.3 miles, Dinner Lake out at 0.5 miles, Verdant Lake roughly 0.7 miles, Ironjaw Lake out at 0.9 miles and Spud Lake roughly 0.9 miles. Rules can differ a short way off, since the county line is near.
Depth here is unknown, so count the lead down before committing. Where the bottom changes texture, fish gather; find that line. The shallow end warms first and pulls fish in ahead of the rest. Species logged across Schoolcraft County include rainbow smelt, alewife, bloater, yellow perch and white sucker. These are county-wide records, so not all of them will be in this water. The near bank of Rumble Lake is often the one people ignore.
Average temperature peaks around 65°F in July and bottoms out near 15°F in January. The freeze arrives properly here and holds. After mid April the shallows warm and the fish move up. Averages suggest open water from about mid April through to roughly early December. Late spring and early autumn carry the year between them. Anyone fishing Rumble Lake regularly works to that calendar.
No public source sets out the position on this bank. A slipway is marked about 0.9 miles from here. There is camping recorded roughly half a mile off. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Where a permit is needed, the nearest town usually sells it. Where parking is tight, arriving early solves most problems. Sprinkler Lake at 0.3 miles is the sensible second choice. Ask locally about Rumble Lake if anything is unclear.
