25-acre lake in Renfrew County, Ontario. The lake tops out around 19 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What follows comes from the same scoring engine that paints the spots above.
The drawn water covers 26 acres wrapped in 1.8 miles of bank, with a single island in the mix. With a shoreline index of 2.6, this water is all arms and coves — edge habitat well beyond its acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Figure 0.4 mi of water from one end to the other, 0.3 mi at the beam. It sits in Renfrew County. Its nearest charted neighbour, Joes Lake, is 2 mi to the south.
Spring brook trout on Murphy Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 6 to 19 ft, and by winter most fish are in 3 to 19 ft. The chart's best answer is Deep basin — deep basin, 16 ft, prime for summer. Prime time lands in 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 |
