47-acre lake near Québec. The lake tops out around 18 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. The season-by-season read for each species follows, from the map's own numbers.

Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 5 to 18 ft; cold water stacks them in 3 to 18 ft. Top water on the chart: Deep basin, a deep basin in the 14 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.

The spring pattern is a shallow one: rainbow trout in 5 to 18 ft. The depth story barely changes: 5 to 18 ft through summer, 4 to 18 ft in winter.

Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.
