Rating depth structure for brown bullhead.
Shared by DepthScout anglers. Exact spots stay private, always.
78-acre lake in Nipissing District, Ontario. The lake tops out around 11 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 81 acres, worked by 2.1 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 0.8 mi long by 0.3 mi wide at the broadest reach. Nipissing District claims this one. Its nearest charted neighbour, Crystal L., is 0 mi to the northwest.
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 11 ft in summer and finish the year down in 3 to 11 ft. If you only fish one area, make it Deep basin: a deep basin around 9 ft that scores prime in winter. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 11 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 3 to 11 ft | dusk | Deep basin (9 ft) | |
| Winter | 3 to 11 ft | midday | Deep basin (9 ft) |
