21-acre lake near Québec. The lake tops out around 26 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.

Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. Expect a summer slide to 7 to 26 ft, then a winter hold in 5 to 26 ft. Start at Break off the point. It's a drop-off holding about 6 ft of water and rates prime come winter. Prime time lands in early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.

Start shallow in spring: brown trout sit in 3 to 25 ft that time of year. Warm water sends them out to 8 to 26 ft; cold water stacks them in 4 to 26 ft. Top water on the chart: Deep basin, a deep basin in the 25 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.
