Antero Reservoir

Large trout call this place home

Antero is Denver Water’s first collection reservoir 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.
