The structure appears to have been similar to the surviving Proserpina Dam near Merida, an earth dam with a stone retaining wall. [4] The upstream retaining wall consists of two parallel rubble-masonry walls about 1 metre (3.3 ft) thick, separated by a concrete-filled space approximately .6 metres (2.0 ft) wide.

The Report of the World Commission on Dams also includes in the "large" category, dams which are between 5 and 15 m (16 and 49 ft) high with a reservoir capacity of more than 3 million cubic metres (2,400 acre⋅ft). [45] Hydropower dams can be classified as either "high-head" (greater than 30 m in height) or "low-head" (less than 30 m in height).
Rio Grande dams and diversions are structures that store water along the Rio Grande or its tributaries, or that divert water for use in irrigation. The first diversions were made by the Pueblo Indians over 1,000 years ago. More permanent diversions were built by the Spanish in New Mexico to feed acequias, or shared irrigation canals. [1]
The Douro's last five dams are in Portugal, and allow for navigation: Pocinho, Valeira, Régua, Carrapatelo, and Crestuma–Lever dams. Vessels with a maximum length of 83 metres (272 ft) and width of 11.4 metres (37 ft) can pass through the five locks. The highest lock, at Carrapatelo Dam, has a maximum lift of 35 metres (115 ft).
Monitoring of the dam revealed abnormal movement. Although dams normally move, the left side of the El Atazar Dam was moving more than the right because a support built on the dam's right made that side less flexible. In 1977 a crack was noticed in the dam. By 1979 the crack had grown to 46 m (150 ft) in length and was repaired.
