The Chiotas Reservoir is closed off by two dams: the Chiotas dam and the Colle di Laura dam. The Chiotas dam, an arch-gravity structure, is 130 meters high and stretches for a length of 230 meters. Its thickness varies from 37.5 meters at its base to 5 meters at the top. The mass gravity Colle di Laura dam is smaller, rectilinear and only 30 meters at its maximum height. Its length is 70 meters. The Chiotas Reservoir has a carrying capacity of 27.3 million cubic meters of water.
