52-acre lake near Québec. The lake tops out around 49 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. Every species below gets its seasonal read from the same numbers driving the chart.

The spring pattern is a shallow one: rainbow trout in 5 to 20 ft. As the season builds they drop to 8 to 30 ft, wintering in 8 to 40 ft. Top water on the chart: Break off the point, a drop-off in the 6 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

|---|---|---|---|---|
| Printemps | 5 to 20 ft | dawn & dusk | Main-lake point (7 ft) | Inline spinner (silver), Small spoon |

Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 6 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

When the water first warms, sauger slide up into 4 to 18 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 15 to 45 ft. If you only fish one area, make it Deep basin: a deep basin around 49 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a bottom bouncer + crawler or a 3-way rig with stickbait rigged through the warm months.

Spring yellow perch on Lac Emerson hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Back-bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
