The rainfall recorded so far in October has proven particularly beneficial for the reservoirs, as it has kept their water levels roughly at the same levels as in September of this year, though slightly below August’s levels as a result of the heavy rainfall that marked the end of the summer month. According to today’s data from the Water Resources Development Department, the total storage level of Cyprus’s reservoirs stands at 35.6% of their total capacity (103,386 ECM) compared to 11.9% (34,703 ECM) during the same period last year, marking a significant improvement compared to the situation in October 2025.
Despite the significant increase in reserves compared to last year, the amount of water stored remains noticeably lower than the levels recorded three and four years ago. Specifically, the amount of water stored currently stands at 103.386 million cubic meters, compared to 34.703 million cubic meters on the same day last year, representing an increase of 68.683 million cubic meters.

Reservoir Levels
Regarding reservoir levels, the highest level is at the Kalopanagiotis Dam, at 100% capacity, followed by the Xyliatos Dam at 75.2% and the Vyzakia Dam at 72%. The Arminos Dam is at 61.6% capacity, the Pomos Dam at 60.5%, the Germasogeia Dam at 48.3%, the Agia Marina Dam at 47.7%, the Argaka Dam at 43.5%, the Polemidia Dam at 43.1%, and the Kannaviou Dam at 42.4%. Lower fill rates are recorded at Evretou at 38.8%, Asprokremmos at 35.7%, Mavrokolympos at 29.7%, Dipotamos at 25.1%, in Kalavaso at 21.8%, and in Lefkara at 17.3%, while the Achna Dam has the lowest fill rate at just 8.3%.
At Kouris, the largest dam with a capacity of 115 million cubic meters, the current fill rate stands at 36.9% and 42.467 million cubic meters, compared to 12.581 million cubic meters and a 10.9% fill rate during the same period last year. Despite the significant increase compared to last year, reservoir levels remain lower than those in October 2022, when they exceeded 76 million cubic meters.
The highest inflows of the decade
A review of data from previous years provided by the Water Development Department reveals significant fluctuations in water inflows to the dams over the past decade, with the highest inflows recorded during the 2018–2019 hydrological year, when they reached 265.04 million cubic meters, followed by the 2021–2022 hydrological year with 153.75 million cubic meters and the 2019–2020 hydrological year with 135.95 million cubic meters. In contrast, the lowest inflows of the decade were recorded in 2024–2025, at just 18.664 million cubic meters, and in 2023–2024, with 24.714 million cubic meters. A significant recovery occurred during the 2025–2026 hydrological year, with total inflows reaching 117.091 million cubic meters.
With regard to water reserves, a significant decline was recorded, with 2025 being the year with the lowest levels. Specifically, in October 2022, the total volume of water stored in the reservoirs stood at 216.229 million cubic meters, while in October 2023 it fell to 155.93 million cubic meters. A further decline followed in October 2024, with reserves falling to 88.607 million cubic meters, and in October 2025 to 39.721 million cubic meters.
A similar trend is observed at Cyprus’s largest dam, Kouris, where the water volume decreased from approximately 77 million cubic meters in October 2022 to approximately 53 million in October 2023 and 29–30 million in October 2024, and to 12–13 million cubic meters in October 2025. It should be noted that this year, reserves at Kouri have shown a significant recovery, reaching 42.467 million cubic meters, however, they remain noticeably below the levels seen in 2022 and 2023.
