167-acre lake in Algoma District, Ontario. The lake tops out around 50 ft. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 168 acres of water rimmed by 5 miles of bank — 3 islands included. With a shoreline index of 2.7, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 66% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 1 mi end to end and 0.8 mi across at its widest. You'll find it in Algoma District. Closest neighbour on DepthScout: Three Loon L., 1 mi northwest of here.
Come spring, look for lake whitefish tight to the bank in 15 to 45 ft. They move out to 15 to 50 ft in summer and finish the year down in 15 to 50 ft. If you only fish one area, make it Deep basin: a deep basin around 50 ft that scores prime in summer. Best bite is early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (46 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 15 to 50 ft | dawn | Deep basin (50 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (20 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 15 to 50 ft | midday & dawn | Deep basin (50 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Come spring, look for cisco (lake herring) tight to the bank in 10 to 40 ft. They move out to 15 to 50 ft in summer and finish the year down in 15 to 50 ft. If you only fish one area, make it Deep basin: a deep basin around 50 ft that scores prime in summer. Best bite is early morning. A vertical flutter spoon (small) or a drop-shot micro plastic is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (50 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 15 to 50 ft | dawn | Deep basin (50 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 15 to 50 ft | dawn | Deep basin (50 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring walleye on Glenn L. hold shallow, usually 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. The chart's best answer is Main-lake point — point, 20 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Secondary point (5 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Main-lake point (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Main-lake point (20 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Main-lake point (20 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 12 to 30 ft. If you only fish one area, make it Main-lake point: a point around 20 ft that scores prime in summer. Best bite is the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Secondary point (5 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (20 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (20 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (50 ft) | Tungsten jig + plastic, Small spoon + spike |
