72-acre lake in Renfrew County, Ontario. The lake tops out around 20 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here is how the season plays out for each species, straight from the data behind the map.
On the chart, First James Lake draws 72 acres inside 1.9 miles of shoreline. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. 74% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.8 mi with a 0.2-mi widest point. The water lies in Renfrew County. Closest neighbour on DepthScout: James Lakes, 1 mi northwest of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Put Back-bay flat first on the milk run — a weed flat near 4 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: muskellunge sit in 3 to 12 ft that time of year. Summer pushes them deeper, 6 to 20 ft, and winter fish settle into 6 to 20 ft. The spot to know is Break off the point, a drop-off in about 18 ft of water that rates prime for muskellunge in fall. Warm-month bites cluster around the evening and early morning. Throw a double-10 bucktail or a topwater (walk-the-dog / creeper) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Back-bay flat (4 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 6 to 20 ft | dusk & dawn | Main-lake point (9 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 5 to 20 ft | midday & dusk | Break off the point (18 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Large rubber, crawled slow |
Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 6 to 20 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (18 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft | midday | Break off the point (18 ft) | Blade bait, Jigging spoon |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. Expect a summer slide to 5 to 20 ft, then a winter hold in 6 to 20 ft. Start at Main-lake point. It's a point holding about 9 ft of water and rates prime come summer. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (9 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (9 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 20 ft | midday | Break off the point (18 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for pumpkinseed tight to the bank in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Start at Shallow bay flat. It's a weed flat holding about 2 ft of water and rates prime come spring. Prime time lands in the evening and early morning. A micro tube or a sponge spider (fly) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (4 ft) | Tungsten ice jig + plastic, Tiny spoon |
Start shallow in spring: brown bullhead sit in 2 to 8 ft that time of year. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 6 to 20 ft. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brown bullhead in winter. Warm-month bites cluster around after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (4 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (4 ft) | |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) |
