1,623-acre lake near Larimer County. The lake tops out around 16 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Boyd Lake draws 1,502 acres inside 10.9 miles of shoreline. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 94% of the surface on the model — that's where the groceries are. End to end it runs roughly 3.6 mi, about 1.1 mi across. You'll find it in Larimer County.

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
