Strontia Springs Dam is six and one-half miles upstream of the mouth of Waterton Canyon on the South Platte River. Completed in 1983 as part of the Foothills Project, this dam towers 243 feet above the South Platte streambed, forming a 1.7 mile-long lake with 98 surface acres. Water is diverted from the reservoir into a 3.4 mile-long tunnel under the mountains to the Foothills Water Treatment Plant.
Getting There: Follow Wadsworth Blvd (Hwy 121) south of C470 past Chatfield Reservoir to the Kassler Center, where you will find public parking.
