The Dolores River is primarily located in the western United States, flowing through parts of Colorado and Utah. Its journey begins in the high mountains of Colorado and concludes as a tributary of the mighty Colorado River in Utah.
Journey of the Dolores River
The Dolores River embarks on its 241-mile journey from its headwaters nestled within the San Juan National Forest in southwestern Colorado. From these mountainous origins, it flows generally northwestward, traversing diverse landscapes across Colorado. As it progresses, the river eventually crosses the state line into eastern Utah. In Utah, it continues its course until it ultimately converges with the Colorado River, marking the end of its significant stretch.
Key Features and Significance
The river is not only a vital natural watercourse but also plays a crucial role in water management and local ecosystems.
McPhee Reservoir
A significant landmark along the Dolores River is the McPhee Reservoir. This reservoir was created in 1986 when the Dolores River was dammed southwest of the town of Dolores, Colorado. McPhee Reservoir is now the fifth-largest reservoir in Colorado by capacity and serves various purposes, including irrigation, recreation, and flood control, impacting the flow and dynamics of the river downstream.
