Costa Blanca reservoir levels surge after rainfall boost

The Costa Blanca is entering summer with reservoir levels dramatically improved following months of heavy rainfall, bringing relief after several years of drought concerns across Alicante province.

Water reserves are now significantly higher than during the recent drought crisis, easing fears over shortages ahead of the busy tourist season when millions of visitors are expected to arrive across the region.

Reservoir levels rise across Alicante Province

After two years of critically low reserves, rainfall since October has transformed water storage levels throughout much of the Costa Blanca.

Current reservoir levels are now around 58 per cent higher than this time last year and more than double the figures recorded during 2024, when prolonged drought conditions left several reservoirs close to historic lows.

According to water management experts, the improved reserves mean water supplies are fully guaranteed this summer despite increased seasonal demand from tourism, agriculture and local residents.

The province’s five main reservoirs are now holding a combined 168 hectometres of water, marking one of the strongest recoveries seen in recent years.

La Pedrera reservoir reaches highest levels in a decade

One of the most significant improvements has been recorded at La Pedrera reservoir in Orihuela, the largest reservoir in Alicante province.

Water levels there have reached figures not seen for more than ten years, largely due to increased transfers through the Tagus-Segura water system following heavy rainfall in central Spain earlier this year.

The Tagus-Segura transfer remains one of the most important water sources for south-east Spain, supplying water to parts of Alicante, Murcia and Almería.

Other Costa Blanca reservoirs recover strongly

Reservoirs, including Amadorio, Guadalest and Beniarrés, have also seen major improvements compared with last year’s drought conditions.

Beniarrés reservoir, which fell to critical levels during the height of the drought, is now approaching half capacity following the wetter winter and spring months.

Although authorities continue encouraging responsible water use, the sharp recovery has brought a far more positive outlook for the Costa Blanca heading into summer.
