218-acre lake in Sudbury District, Ontario. The lake tops out around 70 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Jim Edwards Lake runs 219 acres with 4.8 miles of edge, broken up by an island. A development index of 2.3 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 30% of the water is 15 ft or less, the band where the food chain lives. Figure 1.8 mi of water from one end to the other, 0.4 mi at the beam. You'll find it in Sudbury District. For a second option, Dry Lake lies 2 mi east.
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 Main-lake point, a prime-rated point around 8 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 | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (7 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
