Raising dams to provide water security

The Gross Reservoir Expansion Project will provide water security to the Colorado Front Range from multiple sources and reduce vulnerability in the face of extreme weather events. Stantec’s innovative design will raise the height of the existing dam by 131 feet, ultimately tripling Gross Reservoir’s capacity. The project will be the largest raise of a concrete dam using roller-compacted concrete (RCC) in the world, the tallest dam in Colorado, and will improve water reliability for more than 1.5 million people. This multi-solution approach is part of Stantec and Denver Water’s overall plan to address the water challenges facing the community.
