10-acre lake near Cody Region. The lake tops out around 38 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 10 acres of water rimmed by 0.6 miles of bank. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. About 32% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The water lies in Big Horn County. Closest neighbour on DepthScout: Lake Eunice, 0 mi east of here.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Break off the point, a prime-rated drop-off around 17 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
