Crown length

765.000 m³

Volume of concrete/materials

47 hm³

Reservoir volume

Enciso Dam, located on the Cidacos River, creates a 47 hm³ reservoir designed to regulate water resources and supply irrigation to the Cidacos agricultural area.

It is a straight-axis gravity dam constructed in Roller-Compacted Concrete (RCC), with a maximum height of 103 m and a crest length of 375 m. The structure was executed using the Vibrated Roller-Compacted Concrete (RCCV) technique. The crest width is 8 m.

The upstream face is vertical, while the downstream face is stepped, forming a theoretical slope of 0.8H:1V, with 1.20 m-high steps.

A total of 698,000 m³ of RCC was placed in the dam body. In addition, 67,000 m³ of conventional vibrated concrete were used in specific elements such as foundation leveling, spillway structures, bottom outlets and intake works.

Isabella Lake Dam

California, United States of America

The Isabella Lake Dam islocated 34.80 miles northeast of Bakersfield, California, on the Kern River. The original infrastructure, completed in 1953, comprised a main earthfill dam with a height of 185.04 ft, an auxiliary earthfill dam 100.07 ft high, intake and outlet works, and a service spillway located between the two dams. In 2007, the U.S. Army Corps of Engineers (USACE) imposed operational restrictions on the reservoir due to the need to mitigate significant hydrological, seismic, and internal erosion risks associated with the existing dams and spillway.

Hydroelectric Power Plant Site C (11)

Columbia, Canada

The Site C Hydroelectric Power Station is located on the Peace River, in northern British Columbia, approximately 6.21 miles from Fort St. John. The overall development of the project has been structured into several contracts, with the civil works for the spillways and the powerhouse awarded to a joint venture in which DRAGADOS participates. The scope of the contract includes the construction of an outdoor hydroelectric powerhouse and three spillways, two of which are equipped with gates. The hydraulic regulation system comprises six wagon gates and three radial gates, designed to discharge flows at different operating levels.
