Waterton Canyon/Strontia Springs Reservoir

From bighorns to bike trails, a great place to play

Strontia Springs Dam is 6.5 miles upstream of the mouth of Waterton Canyon on the South Platte River. Water is diverted from the reservoir into a 3.4-mile tunnel under the mountains to the Foothills Water Treatment Plant. Completed in 1983, this dam rises 243 feet above the South Platte streambed.

Recreation notes

Fishing: The stream fishery is managed by Colorado Parks and Wildlife. For lake fishing, note that Strontia Springs is difficult to access from the Bear Creek Trail above Waterton or at the South Platte.

Handicapped accessible fishing pier: A mile and a quarter up the canyon, the site was chosen for its mountain canyon stream location and access to fish habitat structures in the river. Handicapped persons have priority use.

Biking: For the first 6.5 miles of trail, road bikes are suitable. Beyond the dam, mountain bikes are a must.

Hiking: The canyon offers a 6.5-mile hike to the dam. The Colorado Trail continues above the reservoir about 10 miles to the confluence of the North Fork of the South Platte and the South Platte. The Colorado Trail continues to Durango. Waterton also connects to the Roxborough State Park system.

Horseback riding: Waterton Canyon connects to the Chatfield State Parks trail system and the U.S. Forest Service Indian Creek system. Trailer parking is provided at Waterton and at the Discovery Pavilion.

Wildlife viewing: Bighorn sheep and mule deer are often seen in the canyon, which also hosts more than 40 species of birds. To protect the bighorn sheep, dogs are not allowed on the canyon trails.

Special events: Require a permit.
