1,337-acre lake in Cochrane District, Ontario. The lake tops out around 20 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:
Drawn out, this is 1,343 acres of water rimmed by 8 miles of bank, broken up by 2 islands. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. The shallow band under 15 ft claims about 91% of the surface — that's where the groceries are. The basin spans about 2.6 mi end to end and 1.5 mi across at its widest. The water lies in Cochrane District. The nearest mapped water is Hughes Lake, 2 mi to the south.
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 walleye tight to the bank in 4 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 20 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
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 (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (20 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (20 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.

| Winter | 6 to 20 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (20 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Spring puts burbot in skinny water — 6 to 20 ft is the zone. Summer fish stay in 6 to 20 ft, and winter fish hold in 5 to 20 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 20 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 6 to 20 ft chart-limited; documented 25 to 70 ft | night & dusk | Deep basin (20 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 6 to 20 ft chart-limited; documented 50 to 120 ft | night & midday | Deep basin (20 ft) | Heavy jig + cut bait |

| Winter | 5 to 20 ft chart-limited; documented 15 to 60 ft | night & dusk | Deep basin (20 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
Early season cisco (lake herring) use the shallows, holding in 5 to 20 ft. Even in summer they hold at 6 to 20 ft; winter keeps them in 6 to 20 ft. Put Deep basin first on the milk run — a deep basin near 20 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.

Spring sauger on Harris Lake hold shallow, usually 4 to 18 ft. They move out to 6 to 20 ft in summer and finish the year down in 6 to 20 ft. Put Deep basin first on the milk run — a deep basin near 20 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a bottom bouncer + crawler or a 3-way rig with stickbait.

Harris Lake is about 20 ft (6 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, yellow perch, northern pike, burbot, cisco (lake herring), sauger, lake whitefish on Harris Lake.
Break off the point is the top-rated area: a drop-off in about 20 ft of water that rates prime for walleye in fall. The interactive chart above rates every 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.
