Dillon Dam is located in the Rocky Mountains at an elevation of almost 9,000 feet, near the town Dillon, Colorado. The impounded reservoir is a multipurpose facility in the Upper Colorado River Basin and the largest water storage facility in Denver's water system, supplying water to residents throughout the Denver Metro area.
Dillon Damís concrete spillway had experienced significant damage due to freeze-thaw distress, making its repair critical for both maintenance and safety. During a drought in 2002, it became clear that the reservoir would not fill, and Denver Water decided the time was right to implement repairs. The work involved the rehabilitation of the 40-year-old spillway with a new stainless steel liner.
URS conducted analyses, prepared the final rehabilitation design and provided construction oversight. A fast-track approach enabled the design, bidding and construction to be completed in less than nine months so that the reservoir was prepared for the 2003 spring run-off. Today, the reservoir is nearly full and is enjoyed by area residents and visitors.
