156-acre lake near Montana. The lake tops out around 69 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. Here is how the season plays out for each species, straight from the data behind the map.
Spring brook trout on Mussigbrod Lake hold shallow, usually 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 Main-lake point, a point in about 9 ft of water that rates prime for brook trout in spring. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.

|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Small spoon fished deep, Trolled lake-clear wobbler + worm |
