10-acre lake in Powell County, Montana. The lake tops out around 36 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.
The drawn water covers 10 acres wrapped in 0.5 miles of bank. Its 1 shoreline index means few bank features; the contours below do the pattern work. About 47% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Powell County claims this one. If the bite dies, Morrell Lake is 4 mi to the northwest.
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 11 to 36 ft. Break off the point is the standout, a drop-off at roughly 21 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
