105-acre lake near Québec. The lake tops out around 30 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.
Lac Long maps at 105 acres behind 2.6 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. Roughly 67% of the water is 15 ft or less, the band where the food chain lives. Figure 1.2 mi of water from one end to the other, 0.3 mi at the beam. Témiscamingue MRC claims this one. Its nearest charted neighbour, Lac Thompson, is 1 mi to the southeast.

Early season rainbow trout use the shallows, holding in 5 to 20 ft. Summer is an 8 to 30 ft game here, winter a 6 to 30 ft one. The chart's best answer is Break off the point — drop-off, 8 ft, prime for winter. Best bite is early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Secondary point (4 ft) | Inline spinner (silver), Small spoon |
| Été | 8 to 30 ft | dawn & dusk | Break off the point (8 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Automne | 9 to 30 ft | dawn & dusk | Break off the point (8 ft) | Casting spoon, Jerkbait over shoals |
| Hiver | 6 to 30 ft | dawn | Break off the point (8 ft) | Jigging spoon, Tube jig (white) |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 9 to 30 ft, wintering in 9 to 30 ft. Winter walleye concentrate at Deep basin, a prime-rated deep basin around 29 ft. Warm-month bites cluster around the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | Secondary point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Été | 9 to 30 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Automne | 9 to 30 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Hiver | 9 to 30 ft | dusk & dawn | Deep basin (29 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, sauger run shallow here, mostly 4 to 18 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. Winter sauger concentrate at Deep basin, a prime-rated deep basin around 29 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bottom bouncer + crawler or a 3-way rig with stickbait most summer days.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 4 to 18 ft | dawn & dusk | Secondary point (4 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Automne | 9 to 30 ft | dusk & dawn | Break off the point (8 ft) | Jig + big minnow, Blade bait |
| Hiver | 9 to 30 ft | dusk | Deep basin (29 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 9 to 30 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Été | 10 to 30 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Automne | 9 to 30 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Hiver | 9 to 30 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Été | 8 to 20 ft | dawn & dusk | Break off the point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Automne | 6 to 18 ft | midday & dawn | Break off the point (8 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Hiver | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, muskellunge slide up into 3 to 12 ft. Summer is an 8 to 25 ft game here, winter a 9 to 30 ft one. Start at Break off the point. It's a drop-off holding about 8 ft of water and rates prime come fall. The feeding windows run the evening and early morning. Keep a double-10 bucktail or a topwater (walk-the-dog / creeper) rigged through the warm months.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Été | 8 to 25 ft | dusk & dawn | Break off the point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Automne | 8 to 30 ft | midday & dusk | Break off the point (8 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Hiver | 9 to 30 ft | midday | Deep basin (29 ft) | Large rubber, crawled slow |
