325-acre pond in Niagara Regional Municipality, Ontario. The lake tops out around 15 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 1972, a decades-old survey (a transect sounding survey). Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 326 acres of water rimmed by 8.9 miles of bank, with 2 islands in the mix. With a shoreline index of 3.5, this water is all arms and coves — edge habitat well beyond its acreage. The basin spans about 1.5 mi end to end and 0.9 mi across at its widest. The water lies in Niagara Regional Municipality. For a second option, Lake Moodie lies 5 mi south.
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. The spot to know is Main-lake point, a point in about 6 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.
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 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 15 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 5 to 15 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
Structure-wise the chart holds 8 features, led in depth by Deep basin at roughly 15 ft.
