Algarve Dams Hit 91% Capacity, Securing Water Supply for Four Years
After two winters of intense rainfall, the Algarve's six main reservoirs have reached 91 percent capacity -- enough to guarantee the region's water supply for four years, even accounting for dry spells, according to the president of the Portuguese Environment Agency (APA).

"I have no doubt that for two to three years, from the perspective of water quantity, we are completely at ease. The dams are literally full," Jose Pimenta Machado told Lusa on Thursday, adding that Portugal could break national records for stored water by the end of February.
From Rationing to Relief
The turnaround is dramatic. Just two years ago, the Algarve was the epicentre of Portugal's worst drought in decades. Agriculture faced 25 percent water cuts from early 2024, with urban and tourism consumption restricted by 10 to 15 percent. The Bravura reservoir, now at 101 percent capacity, had been under severe usage restrictions for years due to critically low levels.
The recovery began in earnest with heavy rains in late 2025 and accelerated through January and February of this year. Reservoir levels across the region now range from 76 percent at Arade to overflowing at Bravura, a distribution that would have seemed unthinkable 18 months ago.
Not Just a Southern Story
The abundance extends well beyond the Algarve. Pimenta Machado indicated that the entire south of the country has reserves sufficient for two to three years of normal consumption. Nationally, dam storage levels are approaching historic highs.
For the Algarve's tourism industry -- the backbone of the regional economy and a major draw for the hundreds of thousands of foreign residents along the coast -- the water security is consequential. The drought years forced difficult conversations about the sustainability of golf courses, swimming pools, and the general lifestyle infrastructure that attracts retirees and remote workers to the region. With reservoirs full, those pressures ease considerably, though long-term water management planning remains essential.
Agricultural producers who absorbed heavy losses during the rationing period will also benefit. The government had offered some compensation, but many smaller operations struggled with the enforced cutbacks. A return to reliable irrigation should support the region's citrus, almond, and vegetable production through the growing season.
The broader lesson, as Portuguese water authorities have been keen to stress, is that abundance today does not eliminate the need for infrastructure investment. Climate projections for southern Iberia continue to point toward longer dry periods punctuated by more intense rainfall -- exactly the pattern that produced both the drought and the current surplus. Building resilience means capturing and storing water when it comes, not assuming the taps will always run.
