175-acre lake in Timiskaming District, Ontario. The lake tops out around 18 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The season-by-season read for each species follows, from the map's own numbers.
The outline encloses 175 acres, worked by 2.3 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. About 95% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.8 mi long by 0.6 mi wide at the broadest reach. Timiskaming District claims this one. If the bite dies, Shack Lake is 2 mi to the northeast.
Spring brook trout on Conolly Lake hold shallow, usually 2 to 15 ft. They move out to 5 to 18 ft in summer and finish the year down in 3 to 18 ft. Put Deep basin first on the milk run — a deep basin near 15 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 18 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 18 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
