586-acre lake in Kenora District, Ontario. The lake tops out around 7 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The season-by-season read for each species follows, from the map's own numbers.
Bump Lake maps at 589 acres behind 8.4 miles of shoreline, with 7 islands in the mix. A development index of 2.5 means a maze of bays and points: far more casting targets than a round bowl of the same size. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 1.8 mi long by 1 mi wide at the broadest reach. It sits in Kenora District. If the bite dies, Expanse Lake is 2 mi to the southeast.
The spring pattern is a shallow one: yellow perch in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.
