Ribarroja Dam (Spanish: Presa de Ribarroja, Riba-roja) is a concrete gravity dam located in the province of Tarragona, Spain, that impounds the Ebro. About 35 km upstream of Ribarroja dam is Mequinenza dam. About 15 km downstream is .

Empresa Nacional Hidroeléctrica del Ribagorzana S.A. (ENHER) was mandated in 1955[1] by Instituto Nacional de Industria (INI) to build two dams on the Ebro near Mequinenza and Riba-roja. Mequinenza dam was built between 1957 and 1964. Work on Ribarroja dam began during the construction of Mequinenza dam.[2] Ribarroja dam was completed in 1969.[2][3][4] ENHER was acquired by Endesa in 1999.[5]

Dam[]

Ribarroja Dam is a 60 m tall (height above foundation) and 362.4 m long gravity dam with a crest altitude of 76 m. The volume of the dam is 800,000 m³. The dam features a spillway with 7 gates over the dam (maximum discharge 11,670 m³/s) and two bottom outlets with a maximum discharge of 273 (2635) m³/s.[6]

Reservoir[]

At full reservoir level of 70 (maximum 73, minimum 40) m.a.s.l. the reservoir has a surface area of 21.52 (20.29)[3][7] km², a total capacity of 210 million m³ and a length of almost 50[8] km. The maximum (average) depth of the reservoir is 34 (9.7) m.[4]

Power plant[]

The power plant contains 4 Kaplan turbine-generators with a total nameplate capacity of 262.8 MW. Maximum (minimum) hydraulic head is 34 (20) m.[7] Maximum flow is 225 m³/s per turbine.[4]
