Gross Reservoir, Reservoir in Boulder County, Colorado
Gross Reservoir spans across 440 acres at an elevation of 7,225 feet, receiving water from South Boulder Creek and the Continental Divide through Moffat Tunnel.
Denver Water constructed this reservoir in 1954, naming it after their former chief engineer Dwight D. Gross, to establish a water storage facility.
The reservoir contributes to Colorado's water management system, supporting the growing population while maintaining environmental standards in Boulder County.
Visitors can access boating and paddleboarding activities from Memorial Day weekend through September 30, with parking available at the North Shore area.
The ongoing expansion project will make this structure the tallest dam in Colorado, raising its height by 131 feet and increasing storage capacity significantly.
