Izobilnoe Reservoir, Reservoir in Alushta region, Crimea

Izobilnoe Reservoir lies on the Ulu-Uzen River in Crimea, formed where the Sofu-Uzen and Uzen-Bash rivers meet. It is the deepest reservoir on the peninsula, with a maximum depth of 70 m, a water surface of 0.61 km² and a 4 km length. An earth dam 70 m high and 550 m long holds the water.

The reservoir was built during the Soviet era to support agriculture and regional development. It has remained a key resource for local people, though water levels have dropped sharply in recent years due to drought and reduced rainfall.

The reservoir is fed by the Sofu-Uzen and Uzen-Bash rivers, and the Ulu-Uzen flows out of it. Its Crimean Tatar name, Körbekül yapma gölü, links it to the village of Körbekül, now Izobilne. The reservoir supplies fresh water to Alushta and is used for irrigation.

The reservoir lies southwest of Izobilne village in the Alushta region, on the Ulu-Uzen River, reached by road from Alushta. The 70 m earth dam, 550 m long, is the main structure to look for. By 2025 the basin had largely dried out after years of overuse, poor upkeep and extreme heat, so expect exposed bed rather than water.

The reservoir's earth dam stands 70 m high and 550 m long, built in 1979 by SMU-630 of the Kyivhydrospetsbud trust. Its design capacity exceeded 36 million m³, yet the planned volume was 13.25 million m³. Prolonged overuse, poor upkeep during the Russian occupation and extreme heat left it essentially dry in 2025.
