305-acre lake in Sudbury District, Ontario. The lake tops out around 39 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. What the data behind the map says about each species, season by season:
The drawn water covers 306 acres wrapped in 8.7 miles of bank — 10 islands included. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. 46% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 2.4 mi end to end and 0.6 mi across at its widest. Sudbury District claims this one. Its nearest charted neighbour, Potier Lake, is 1 mi to the northeast.
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.

Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (9 ft) | Tip-ups, Large jigging spoon |
