Ivaylovgrad Reservoir
Haskovo
Ivaylovgrad Reservoir is situated on the Arda River in the eastern Rhodope Mountains of southern Bulgaria, near the border with Greece. Constructed between 1959 and 1964, the reservoir serves multiple purposes including electricity generation, irrigation, and flood control as part of the Arda Hydropower Cascade. The dam is a concrete gravity structure standing 73 meters tall and 365 meters long, with an integrated hydroelectric plant of 104 MW capacity. The reservoir covers an area of 15.1 square kilometers with a shoreline of 64 kilometers, largely enveloped by dense deciduous forests. The surrounding region is an Important Bird Area, hosting 163 bird species including significant populations of white-tailed eagle, booted eagle, and osprey. Initially, plans for a larger reservoir and a nuclear power plant were considered but abandoned due to environmental and military concerns. Today, Ivaylovgrad Reservoir remains a key natural and infrastructural landmark in Haskovo Province, balancing energy production with ecological preservation.

History
Ivaylovgrad Reservoir was constructed from 1959 to 1964 on the Arda River to support hydroelectric power and irrigation needs.
The project submerged four villages and was initially planned to be larger, but expansion was limited to protect upstream mining operations.
Later proposals to build a nuclear power plant near the reservoir were abandoned due to the region's proximity to international borders and related security concerns.
Over time, sediment accumulation has reduced the reservoir's capacity from its original design volume.
