32-acre lake in Timiskaming District, Ontario. The lake tops out around 26 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 1969, a decades-old survey (an MNRF lake survey). Here is how the season plays out for each species, straight from the data behind the map.
Mowat Lake maps at 32 acres behind 1.2 miles of shoreline. With a 1.6 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 97% of the surface — that's where the groceries are. Call it 0.5 mi long by 0.2 mi wide at the broadest reach. Timiskaming District claims this one. Its nearest charted neighbour, Mahon Lake, is 1 mi to the west.
Early season brook trout use the shallows, holding in 2 to 15 ft. Summer is an 8 to 26 ft game here, winter a 3 to 20 ft one. The chart's best answer is Deep basin — deep basin, 24 ft, prime for summer. Best bite is early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 26 ft | dawn & dusk | Deep basin (24 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (1 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 5 features, led in depth by Deep basin at roughly 24 ft.
