Colorado Piedra River

Characteristics updated 12 days ago
Flow updated about 6 hours ago

The Piedra River, also known as El Rio De La Piedra Parada, is a picturesque waterway that carves its way through the rugged terrain of the San Juan Mountains. Originating from the confluence of its East Fork and Middle Fork, the river embarks on a 40-mile journey, showcasing the serene beauty of the San Juan National Forest.

As it meanders southwards, the Piedra River flows through open meadows before plunging into deep, isolated box canyons. Along its course, it is fed by tributaries such as O'Neal Creek, Williams, Weimuche, and Sand Creeks, enhancing its volume and vitality. The river's path is marked by a series of natural landmarks, including the confluence with the First Fork Piedra River and the scenic valleys of Heffin and Yellowjacket Creeks.

The Piedra River is not just a feast for the eyes; it's a haven for wildlife. Its somewhat remote location contributes to an abundance of fauna, including river otters, which thrive in its waters. The river's ecosystem is a delicate balance, sustained by the purity of the mountain runoff and the shelter provided by the canyons.

For the adventurous spirit, the Piedra River offers a range of outdoor activities. Whitewater rafting enthusiasts can navigate its Class IV rapids, while anglers can find solace in fly fishing for trout in the river's more tranquil stretches. The river is also home to the Piedra River Hot Springs, where visitors can soak in the naturally occurring warm waters after a rewarding hike.

In its final leg, the Piedra River widens into a valley, running alongside State Highway 151, and eventually joins the San Juan River at Navajo Lake, near the town of Arboles. This confluence, now submerged beneath the waters of Navajo Reservoir, marks the end of the river's majestic journey through Southern Colorado.

The Piedra River, with its blend of tranquility and wildness, is a true gem of the San Juan Mountains, offering a glimpse into the untouched beauty of nature.
