534-acre lake in Timiskaming District, Ontario. The lake tops out around 80 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Beaverhouse Lake runs 537 acres with 14 miles of edge, broken up by 14 islands. An index of 4.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 23% of the surface — that's where the groceries are. Call it 2.5 mi long by 1.4 mi wide at the broadest reach. The water lies in Timiskaming District. For a second option, Sourdough Lake lies 1 mi southeast.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Back-bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Back-bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (18 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (18 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Back-bay flat (6 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: brown bullhead in 2 to 8 ft. As the season builds they drop to 3 to 12 ft, wintering in 10 to 25 ft. Top water on the chart: Back-bay flat, a weed flat in the 6 ft range, prime in spring. Time it for after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Back-bay flat (6 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (6 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (6 ft) | |
| Winter | 10 to 25 ft | midday | open water |
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Summer pushes them deeper, 24 to 80 ft, and winter fish settle into 15 to 60 ft. The spot to know is Deep basin, a deep basin in about 76 ft of water that rates prime for burbot in summer. Warm-month bites cluster around after dark and midday. Throw a heavy jig + cut bait until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (76 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 24 to 80 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (76 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (76 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (17 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. By summer they slide out to 40 to 80 ft, and by winter most fish are in 20 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 76 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (17 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (76 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (17 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (17 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 20 to 45 ft. Fall smallmouth bass concentrate at Secondary point, a prime-rated point around 16 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (7 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (17 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (16 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (17 ft) | Blade bait, Hair jig |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Break off the point — drop-off, 17 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (17 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (17 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (17 ft) | Jigging spoon + minnow head, Rattle bait |
