59-acre lake near Ontario. The lake tops out around 34 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
In spring, brook trout run shallow here, mostly 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 29 ft of water that rates prime for brook trout in summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.

Start shallow in spring: burbot sit in 10 to 34 ft that time of year. Summer fish stay in 10 to 34 ft, and winter fish hold in 9 to 34 ft. If you only fish one area, make it Deep basin: a deep basin around 29 ft that scores prime in spring. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
