Rating depth structure for brown bullhead.
Shared by DepthScout anglers. Exact spots stay private, always.
27-acre lake in Algoma District, Ontario. The lake tops out around 8 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 1979, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Traced from the shoreline, Mellon Lake runs 27 acres with 1.2 miles of edge. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 0.4 mi long by 0.2 mi wide at the broadest reach. The water lies in Algoma District. The nearest mapped water is Gander Lake, 0 mi to the northwest.
Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. Summer fish stay in 2 to 8 ft, and winter fish hold in 2 to 8 ft. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 7 ft. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | open water | |
| Summer | 2 to 8 ft | night & dusk | Deep basin (7 ft) | |
| Fall | 2 to 8 ft | dusk | Deep basin (7 ft) | |
| Winter | 2 to 8 ft | midday | Deep basin (7 ft) |
Count 4 structure marks on this chart. The deepest, Deep basin, sits near 7 ft.
