203-acre lake in Algoma District, Ontario. The lake tops out around 92 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 1971, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
The outline encloses 204 acres, worked by 6.9 miles of shoreline, broken up by 15 islands. The 3.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 52% of this chart. Call it 1.2 mi long by 0.7 mi wide at the broadest reach. It sits in Algoma District. If the bite dies, Christman L. is 1 mi to the southwest.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. Expect a summer slide to 28 to 92 ft, then a winter hold in 20 to 80 ft. Start at Deep basin. It's a deep basin holding about 89 ft of water and rates prime come summer. Prime time lands in early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (12 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 28 to 92 ft | dawn | Deep basin (89 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Break off the point (12 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (89 ft) | White tube jig, Airplane jig |
7 pieces of structure are mapped here — Deep basin, around 89 ft, is the deepest of them.
