22-acre lake in Thunder Bay District, Ontario. The lake tops out around 43 ft. The depth data here comes from the Ontario MNRF survey of 2008 (an MNRF lake survey). Species by species, here's what the data says the year looks like.
Jessica Lake maps at 22 acres behind 1.3 miles of shoreline — one island included. With a 2 development index there's bank structure worth casting at, in moderation. The shallow band under 15 ft claims about 72% of the surface — that's where the groceries are. Figure 0.3 mi of water from one end to the other, 0.2 mi at the beam. Thunder Bay District claims this one. Its nearest charted neighbour, Annette Lake, is 1 mi to the southwest.
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 13 to 43 ft, wintering in 5 to 35 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 12 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (1 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
