In the wee hours of June 3, he got up every hour to check the livestream of workers laying the final layer of roller-compacted concrete on the dam, a major milestone more than two decades in the making. At 3 a.m., workers placed the last foot of concrete — completing the main structure of what is now Colorado’s tallest dam and finishing a long-held plan by Denver Water to expand Gross Reservoir. Martin, the program manager for the dam project, had worked for 12 years on the $600 million effort to replace the old Gross Dam with one that is 131 feet taller, tripling the reservoir’s storage. Crews still have some finishing work remaining, he said, but the major work to raise the dam is now complete.
