1,315-acre reservoir near Grand County. The lake tops out around 24 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Species by species, here's what the data says the year looks like.
Drawn out, this is 1,280 acres of water rimmed by 11.6 miles of bank — 8 islands included. That shoreline is heavily fingered (development index 2.3) — bays, points and pockets everywhere, which multiplies the fishable edge. Roughly 81% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 3.1 mi of water from one end to the other, 1 mi at the beam. You'll find it in Grand County.
