55-acre lake in Nipissing District, Ontario. The lake tops out around 45 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 1942, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
The drawn water covers 56 acres wrapped in 2 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 75% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 0.8 mi, about 0.3 mi across. Nipissing District claims this one. Its nearest charted neighbour, Hiram Lake, is 1 mi to the north.
Spring lake trout on Blackfox Lake hold shallow, usually 10 to 40 ft. They move out to 14 to 45 ft in summer and finish the year down in 11 to 45 ft. Put Deep basin first on the milk run — a deep basin near 34 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (16 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 14 to 45 ft | dawn | Deep basin (34 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 9 to 45 ft | dusk & dawn | Main-lake point (6 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 11 to 45 ft | dawn | Deep basin (34 ft) | White tube jig, Airplane jig |
Count 6 structure marks on this chart. The deepest, Deep basin, sits near 34 ft.
