650-acre lake near Québec. The lake tops out around 60 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. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lac Larouche runs 650 acres with 9.1 miles of edge. The 2.6 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 18% of this chart. Figure 3.4 mi of water from one end to the other, 1.2 mi at the beam. The water lies in La Vallée-de-la-Gatineau MRC. The nearest mapped water is Lac Louis, 2 mi to the south.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 13 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
| Saison | Profondeur | Meilleure fenêtre | Commencer à | Leurres |
|---|---|---|---|---|
| Printemps | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Été | 10 to 30 ft | dawn & dusk | Break off the point (13 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |

Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Summer pushes them deeper, 18 to 60 ft, and winter fish settle into 15 to 60 ft. The spot to know is Deep basin, a deep basin in about 60 ft of water that rates prime for lake trout in summer. Warm-month bites cluster around early morning. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.

When the water first warms, lake whitefish slide up into 15 to 45 ft. By summer they slide out to 18 to 60 ft, and by winter most fish are in 18 to 60 ft. If you only fish one area, make it Deep basin: a deep basin around 60 ft that scores prime in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.

Early season walleye use the shallows, holding in 4 to 15 ft. Summer is a 15 to 35 ft game here, winter a 20 to 40 ft one. The chart's best answer is Break off the point — drop-off, 13 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
