Gross Reservoir, Reservoir in Boulder County, Colorado
Gross Reservoir is a water storage facility in Boulder County at an elevation of about 7,200 feet, fed by South Boulder Creek and the Moffat Tunnel which brings water from across the Continental Divide. The reservoir sits in a wide mountain valley and stores water for regional use.
Denver Water built this reservoir in 1954, naming it after Dwight D. Gross, a former chief engineer of the utility. The facility was created to provide reliable water storage for the region's growing communities.
The reservoir contributes to Colorado's water management system, supporting the growing population while maintaining environmental standards in Boulder County.
The reservoir is open for boating and paddling activities from late May through late September, with parking areas at North Shore. Visitors should be prepared for the high elevation and changing mountain weather conditions.
The area is home to black bears and mountain goats, which occasionally can be spotted from overlooks. Seeing wildlife is an unexpected aspect of visiting this mountain water body.
