181-acre lake in Kenora District, Ontario. The lake tops out around 33 ft. The depth data here comes from the Ontario MNRF survey of 1987 (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Plum Lake maps at 182 acres behind 4.3 miles of shoreline. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 45% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1.1 mi end to end and 0.7 mi across at its widest. Kenora District claims this one. If the bite dies, Silver Lake is 3 mi to the southeast.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 10 to 33 ft, and winter fish settle into 10 to 33 ft. The spot to know is Break off the point, a drop-off in about 12 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 10 to 33 ft | dusk & dawn | Break off the point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 10 to 33 ft | dusk & night | Break off the point (12 ft) | Jigging rap, Jig + big minnow |
| Winter | 10 to 33 ft | dusk & dawn | Deep basin (33 ft) | Jigging spoon + minnow head, Rattle bait |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 10 to 33 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 8 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 10 to 33 ft | midday | Deep basin (33 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 10 to 33 ft | midday & dawn | Deep basin (33 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring muskellunge on Plum Lake hold shallow, usually 3 to 12 ft. They move out to 8 to 25 ft in summer and finish the year down in 10 to 33 ft. Put Break off the point first on the milk run — a drop-off near 12 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (8 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Secondary point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (12 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 10 to 33 ft | midday | Deep basin (33 ft) | Large rubber, crawled slow |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Main-lake point is the standout, a point at roughly 6 ft, rated prime for summer rock bass. Plan around the evening in the warm months. A ned rig (small) or a marabou jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (6 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (6 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (12 ft) | Small tube jig, Inline spinner |
