Glen Canyon National Recreation Area, AZ (No. 8)

Glen Canyon Dam's most vital purpose is to provide storage to ensure enough water flows from the Upper Colorado River Basin to the lower, especially in drought years. The 1922 Colorado River Compact requires annual delivery of 7.5 million acre-feet (9.3 km3) to the Lower Basin states of Arizona, California and Nevada; the 1944 treaty with Mexico obligates the U.S. to allow at least 1.5 million acre-feet (1.9 km3) for use in the Mexican states of Baja California and Sonora. Glen Canyon Dam must supply at least 8.23 million acre-feet (10.15 km3) of this water; the remaining 770,000 acre-feet (0.95 km3) comes from other tributaries of the Colorado River.[125] The required release from Glen Canyon is averaged over a 10-year period, so releases in each year may be higher or lower depending on the amount of runoff. In wetter years, the Bureau of Reclamation may decide to release extra water from Glen Canyon Dam if the level of Lake Powell exceeds the "equalization tier", an elevation determined by the difference in storage between Lake Powell and Lake Mead.

Most of Lake Powell's inflow originates as summer snowmelt from the Rocky Mountains of Colorado, Utah and Wyoming. Releases are made over a water year of October 1–September 30, since the annual snowpack begins to accumulate in late autumn. On April 1 of each year, the Bureau of Reclamation releases its official forecast of the April–July (snowmelt season) runoff, and adjusts releases from Glen Canyon Dam accordingly to maintain Lake Powell at a safe level. An accurate forecast is vital to prevent uncontrolled spilling, which would waste water that could have been used for power generation. Although the snowpack typically reaches its peak and begins to melt in April, the picture can occasionally change unexpectedly and dramatically – either due to a hot and dry spring that evaporates snow before it can melt, or an extremely wet spring as occurred in May 1983. After the near disaster in 1983, the USBR has maintained a minimum of 2.4 million acre-feet (3.0 km3) of flood-storage space in Lake Powell at the beginning of each year, to guard against unanticipated high runoff.

Dams And Levees| GZA

Dams and levees play a crucial role in water management, flood protection, and land reclamation. These structures are vital for controlling the flow and distribution of water in various environments, from flood-prone areas to regions that rely on hydroelectric power. By providing storage, flood defense, and water supply regulation, dams and levees have a significant impact on both the economy and the environment.A dam is a large barrier constructed across rivers or streams to control the flow of water. Dams serve multiple purposes, including water storage, flood control, irrigation, and power generation. By holding back water, dams create reservoirs that provide water for drinking, agriculture, industry, and hydroelectric power.

Our dams and levees safety engineering evaluations are typically identified during our visual inspections.  GZA's dam and levee safety engineers are well-versed in all aspects of hydrologic and hydraulic (H&H) analyses, geotechnical and structural evaluations, and gates and valves assessments. Our engineering evaluations are performed to determine if the dam/levee complies with current regulatory requirements and/or generally accepted dam/levee safety guidelines.  We are very familiar with the state and federal dam safety regulations as well as dam/levee safety design guidelines published by the USACE, FERC and USBR.

Dig those hats!  

Today, on National Hat Day, we are sharing with you this 1939 image of workers on the Parker Dam U.S. Bureau of Reclamation (USBR) project digging a trench using a Caterpillar tractor. Both are wearing hats, so we are wondering who should be wearing the fancy hats in the foreground.

Glen Canyon National Recreation Area, AZ (No. 3)

Glen Canyon Dam is a concrete arch-gravity dam in the southwestern United States, located on the Colorado River in northern Arizona, near the town of Page. The 710-foot-high (220 m) dam was built by the Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than 25 million acre-feet (31 km3). The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat.

A dam in Glen Canyon was studied as early as 1924, but these plans were initially dropped in favor of the Hoover Dam (completed in 1936) which was located in the Black Canyon. By the 1950s, due to rapid population growth in the seven U.S. and two Mexican states comprising the Colorado River Basin, the Bureau of Reclamation deemed the construction of additional reservoirs necessary. The Glen Canyon Dam remains a central issue for modern environmentalist movements. Beginning in the late 1990s, the Sierra Club and other organizations renewed the call to dismantle the dam and drain Lake Powell in Lower Glen Canyon. Glen Canyon and Lake Powell are managed by the Department of the Interior within Glen Canyon National Recreation Area.
