The Colorado River Storage Project is a United States Bureau of Reclamation project designed to oversee the development of the upper basin of the Colorado River. The project provides hydroelectric power, flood control and water storage for participating states along the upper portion of the Colorado River and its major tributaries. [1]
Dams on tributaries are listed if they are taller than 250 ft (76 m), store more than 50,000 acre⋅ft (62,000 dam 3), or are otherwise historically notable. Tributary dams are organized into two lists; those in the Upper Basin, defined as the half of the Colorado River basin above Lee's Ferry, Arizona, and the Lower Basin.
Huerfano River: Irrigation dam. Cucharas #5 Dam: 135 ft (41 m) 2019 Huerfano County: Cucharas River: This 1910 irrigation dam experienced structural problems throughout its life, including a partial failure in 1987 which resulted in the emergency dynamiting of a spillway.
A large dam on the Colorado River had been envisioned since the 1920s. In 1928, Congress authorized the Reclamation Service (today's U.S. Bureau of Reclamation, or USBR) to build the Boulder Canyon Project, whose key feature would be a dam on the Colorado in Black Canyon 30 miles (48 km) southeast of Las Vegas, Nevada.
The flushing flow method involves partially or completely emptying the reservoir behind a dam to erode the sediment stored on the bottom and transport it downstream. [7] [6] Flushing flows aim to restore natural water and sediment fluxes in the river downstream of the dam, however the flushing flow method is less costly compared to removing dams or constructing bypass tunnels.

Glen Canyon Dam viewed from inside lower Glen Canyon. Glen Canyon Dam, a concrete arch dam on the Colorado River in the American state of Arizona, is viewed as carrying a large amount of risk, most notably due to siltation. [citation needed] The Colorado and San Juan rivers deposit large volumes of silt into Lake Powell, slowly decreasing its ...
Below Imperial Dam the remnants of the Colorado river lessen in gradient and in its lower course flows through the Colorado Desert in a broad sedimentary plain upriver from Yuma, Arizona, where it is joined by the Gila River. The Gila was once one of the Colorado's largest tributaries, draining a huge swath of Arizona and western New Mexico.
