Strontia Springs Dam is a principal feature of the Foothills Project on the South Platte River, 25 miles southwest of Denver, Colorado. The dam provides for storage and diversion of water in an expansion of the water supply of the Denver metropolitan area. The dam has a 2600 square mile drainage area with a total spillway capacity of 90,000 cubic feet per second. The dam is a concrete double curvature thin arch structure with a maximum height of 292 feet. Construction included a 15 foot diameter horseshoe tunnel for diversion, approximately 246,000 cubic yards of excavation, 48,500 linear feet of grout holes, 97,600 cubic yards of concrete for the arch dam and 10,276 cubic yards of concrete for remaining structures. During construction, special care was taken with winterization, curing, and post cooling of concrete.
