49-acre lake in Algoma District, Ontario. The lake tops out around 69 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 1987 (an MNRF lake survey). The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Redrock Lake runs 50 acres with 2.8 miles of edge, with a single island in the mix. An index of 2.8 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 89% of this chart. Tip to tip the water measures near 0.6 mi with a 0.4-mi widest point. You'll find it in Algoma District. For a second option, Maki Lake lies 0 mi southwest.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Spring brook trout concentrate at Secondary point, a prime-rated point around 3 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (2 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (3 ft) | Small spoon (orange), Spinner |

When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 15 to 35 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|

Put Secondary point first on the milk run — a point near 3 ft that grades prime for summer. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.
