126-acre lake in Haliburton County, Ontario. The lake tops out around 10 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. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Haas Lake draws 126 acres inside 2.6 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1 mi, about 0.3 mi across. The water lies in Haliburton County. The nearest mapped water is Black Lake, 1 mi to the east.
Come spring, look for walleye tight to the bank in 3 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. If you only fish one area, make it Break off the point: a drop-off around 6 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 | 3 to 10 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 3 to 10 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (6 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 3 to 10 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (6 ft) | Jigging rap, Jig + big minnow |
| Winter | 3 to 10 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (10 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, muskellunge run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Break off the point is the standout, a drop-off at roughly 6 ft, rated prime for fall muskellunge. Time it for the evening and early morning. You won't need more than a double-10 bucktail or a topwater (walk-the-dog / creeper) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft chart-limited; documented 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 3 to 10 ft chart-limited; documented 8 to 25 ft | dusk & dawn | Main-lake point (4 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 3 to 10 ft chart-limited; documented 8 to 30 ft | midday & dusk | Break off the point (6 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 3 to 10 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (10 ft) | Large rubber, crawled slow |
Start shallow in spring: smallmouth bass sit in 3 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 3 to 10 ft covers winter. The spot to know is Main-lake point, a point in about 4 ft of water that rates prime for smallmouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Winter | 3 to 10 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (6 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.

Haas Lake is about 10 ft (3 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, muskellunge, smallmouth bass, largemouth bass on Haas Lake.
Break off the point is the top-rated area: a drop-off in about 6 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
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.
