Antero Reservoir

Large trout call this place home

Antero is derived from the Spanish word "first," because it was the uppermost dam on the South Platte River. Geologists believe Antero Reservoir occupies the site of a former lake-bed. While Green Lake lies submerged within the reservoir, an extinct volcano, Buffalo Peaks, looms above.
