El Rio de Nuestra Señora de Dolores
The Dolores River flows for nearly 250 miles from its headwaters in the San Juan Mountains of Southwest Colorado to its confluence with the Colorado River near the Dewey Bridge boat ramp. A river trip from Bradfield Bridge below Mcphee Reservoir to Glen Canyon has potential to be one of the longest continual stretches of river in the Colorado River Basin. However the Dolores is rarely navigable by raft or any craft above the rivers confluence with the San Miguel.
The Dolores river consists of class I – IV whitewater rapids and travels through five major Western life zones from the High Alpine at its headwaters to the Upper Sonoran life zone at its confluence. The diverse ecology, geology and hydrology of this river make for an exciting and engaging experience for Boatmen. The river is divided into four main river sections for recreational boating.
