9-acre lake in Norway. The lake tops out around 20 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:
The drawn water covers 9 acres wrapped in 0.7 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. 94% of the surface is littoral (under ~15 ft) — cover, weeds and forage water.

Start shallow in spring: brown trout sit in 2 to 20 ft that time of year. Summer keeps them at 6 to 20 ft, and they winter in 3 to 20 ft. Top water on the chart: Break off the point, a drop-off in the 10-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.
