67-acre lake in Haliburton County, Ontario. The lake tops out around 25 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 the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Black Lake maps at 67 acres behind 1.7 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. 76% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.3 mi across. It sits in Haliburton County. Its nearest charted neighbour, Haas Lake, is 1 mi to the west.
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.

The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. The spot to know is Break off the point, a drop-off in about 14 ft of water that rates prime for walleye in fall. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (10 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 25 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (14 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 25 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (14 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 25 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (24 ft) | Jigging spoon + minnow head, Rattle bait |
Early season muskellunge use the shallows, holding in 3 to 12 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 8 to 25 ft. Put Break off the point first on the milk run — a drop-off near 14 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a double-10 bucktail or a topwater (walk-the-dog / creeper) and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Main-lake point (10 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 7 to 25 ft chart-limited; documented 8 to 30 ft | midday & dusk | Break off the point (14 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 8 to 25 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (24 ft) | Large rubber, crawled slow |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. The chart's best answer is Main-lake point — point, 10 ft, prime for fall. Best bite is early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |

| Winter | 8 to 25 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (14 ft) | Blade bait, Hair jig |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 24 ft.

Black Lake is about 25 ft (8 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey).
Anglers target walleye, muskellunge, smallmouth bass on Black Lake.
Break off the point is the top-rated area: a drop-off in about 14 ft of water that rates prime for walleye in fall. Open the map above to see every rated spot for each species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
