24-acre lake in Algoma District, Ontario. The lake tops out around 38 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 1975, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Dolan Lake maps at 24 acres behind 1 miles of shoreline. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. About 47% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.4 mi, about 0.2 mi across. It sits in Algoma District. If the bite dies, Oval Lake is 1 mi to the north.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 30 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (30 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (6 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
4 pieces of structure are mapped here — Deep basin, around 38 ft, is the deepest of them.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Dolan Lake specifically, so confirm the current rules before you fish.
