9-acre lake near Cody Region. The lake tops out around 31 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Granite Lake runs 9 acres with 0.6 miles of edge. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 43% of the surface on the model — that's where the groceries are. Figure 0.3 mi of water from one end to the other. You'll find it in Big Horn County. For a second option, Cliff Lake lies 1 mi east.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for summer brook trout. Time it for early morning and the evening. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
