24-acre lake near Québec. The lake tops out around 10 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's the year, species by species, as the scoring engine sees it.
Lac la Retenue maps at 24 acres behind 0.9 miles of shoreline. Nearly circular (index 1.3), so the story is the bottom, not the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. It sits in La Côte-de-Beaupré MRC. If the bite dies, Lac Tourbillon is 6 mi to the west.

When the water first warms, brook trout slide up into 1 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 2 to 10 ft. If you only fish one area, make it Deep basin: a deep basin around 8 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.

| Printemps | 1 to 10 ft | dawn & dusk | Main-lake point (3 ft) | Small inline spinner (gold), Tiny spoon |

Start shallow in spring: brown trout sit in 1 to 10 ft that time of year. They don't go far with the seasons — 3 to 10 ft covers summer, 1 to 10 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 3 ft range, prime in summer. Fish it in after dark and early morning and you'll meet the bite. Throw a spoon at the thermocline or a deep stickbait (night) until the fish tell you otherwise.

Come spring, look for landlocked salmon tight to the bank in 1 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Deep basin. It's a deep basin holding about 8 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.

Spring puts yellow perch in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Deep basin is the standout, a deep basin at roughly 8 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

Spring northern pike on Lac la Retenue hold shallow, usually 2 to 8 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
