Los Campitos, Spain

Los Campitos Reservoir (Embalse Los Campitos) is located in the Anchieta ravine, near Los Campitos, above Santa Cruz de Tenerife, in the Canary Islands. The dam was constructed in the 1970s, after which it was discovered that the basin could not hold water. It was subsequently waterproofed in 1978, but has never held water. It was remodeled in the early 2000s, with an enclosed tank and a new pipeline constructed. A study has been conducted to build a hydroelectric plant at the reservoir.

The dam was constructed in the Anchieta ravine to increase the water supply to Santa Cruz de Tenerife. It was constructed by the Spanish Ministry of Public Works (Ministerio de Obras Públicas), starting in 1969, and cost 373 million pesetas. The dam is 54 metres (177 ft) tall, and is made of reinforced concrete. It encloses a basin with an area of 130,000 square metres (1,400,000 sq ft), which could hold 4.2 million cubic metres of water.
