251-acre lake in Sudbury District, Ontario. The lake tops out around 79 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Broker Lake runs 251 acres with 8.5 miles of edge. That shoreline is heavily fingered (development index 3.8) — bays, points and pockets everywhere, which multiplies the fishable edge. About 26% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 2.2 mi of water from one end to the other, 0.7 mi at the beam. You'll find it in Sudbury District. For a second option, Hunter Lake lies 1 mi south.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 24 to 79 ft; cold water stacks them in 20 to 79 ft. Top water on the chart: Deep basin, a deep basin in the 67 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (20 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 24 to 79 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (67 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (20 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 79 ft chart-limited; documented 20 to 80 ft | dawn | Deep basin (67 ft) | White tube jig, Airplane jig |
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. Summer is a 24 to 79 ft game here, winter a 20 to 60 ft one. Start at Deep basin. It's a deep basin holding about 67 ft of water and rates prime come summer. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.

|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (36 ft) | Small silver spoon, Tiny swim jig (white) |

Spring yellow perch on Broker Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (36 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Break off the point (36 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (6 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (6 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (6 ft) | Tungsten ice jig + plastic, Tiny spoon |
