15-acre lake near Québec. The lake tops out around 80 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. What the data behind the map says about each species, season by season:
Traced from the shoreline, Lac Balthazar runs 15 acres with 0.6 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. About 5% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.3 mi end to end. The water lies in Mékinac MRC. The nearest mapped water is Lac Gaspard, 0 mi to the north.

In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Spring brook trout concentrate at Shallow bay flat, a good-rated feeding flat around 11 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.

Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 78 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.

Spring puts landlocked salmon in skinny water — 1 to 15 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 40 ft. Deep basin is the standout, a deep basin at roughly 78 ft, rated good for summer landlocked salmon. Plan around early morning and the evening in the warm months. A dodger + streamer down deep or a thin spoon on lead core covers the summer program.

Early season lake whitefish use the shallows, holding in 15 to 45 ft. Expect a summer slide to 24 to 80 ft, then a winter hold in 25 to 70 ft. Put Deep basin first on the milk run — a deep basin near 78 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a blade bait vertical or a small jigging spoon and you're in the game.

Put Deep basin first on the milk run — a deep basin near 78 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a vertical flutter spoon (small) or a drop-shot micro plastic and you're in the game.

Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 15 to 35 ft in summer and finish the year down in 20 to 40 ft. If you only fish one area, make it Back-bay flat: a feeding flat around 17 ft that scores good in summer. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

|---|---|---|---|---|
| Printemps | 4 to 15 ft | dusk & dawn | open water | 1/8 oz jig + minnow, Hair jig |
