Cyprus reservoirs 39.3% full by early September, with just 1% of water left in Achna

By early September, Cyprus’s 21 reservoirs were 39.3% full, holding 117.9 million cubic metres of water out of a total capacity of 300 million cubic metres. The data was published by the Water Development Department (WDD).

The situation was noticeably worse a year ago: at the beginning of September 2025, the reservoirs were 15.5% full, with reserves of 46.4 million cubic metres. Over the year, the volume of water in the reservoirs increased almost 2.5-fold.

At the same time, the summer came at a high cost: over the past three months, when evaporation is at its highest due to the heat, total reserves fell by 7 million cubic metres.

The differences between individual reservoirs remain substantial. Four facilities are more than 85% full: Kalopanagiotis, the island’s smallest reservoir, is at 100%; Klirou-Malounta-Akaki at 89.7%; Solea at 88%; and Tamasos at 86%. Three more are in the 68–85% range: Xyliatos (82%), Vizakia (79%) and Pomos (70%).

Four reservoirs have fallen into the critical zone, below 35%: Dipotamos (29%), Kalavasos (23%), Lefkara (18%) and Achna, where just 1% of capacity remains. Another six facilities are 35–51% full, including Cyprus’s largest reservoir, Kouris (39%), and Asprokremmos (38%).

The best hydrological year in the department’s five-year statistics remains 2022, when Cyprus’s reservoirs were 76% full in September.
