Site description The IBA is situated on the northern mountainside of the Turkestan range. Daganasay and Kattasay Reservoirs are located on the same altitude 50-60 km from each other. Daganasay Reservoir is situated in Cagdiyskiy region 9 km to the south of the district centre, Gonchi. The Dagana river and Mangytsay and Koganisay tributaries flow into it. The total volume of the reservoir is 42 million m3. The maximum area is 280 hectares, depth – 18m. Towards the end of the irrigation season its area reduces to 35-40 hectares and the depth to 3 m. The reservoir is oligotrophic. The soil of the bottom is formed as a result of the accumulation of alluvial silt. 132 species of algae are known. Migrating waterbirds use the site from October and Anseriformes, Charadriformes and Falconiformes winter. Kattasay Reservoir is situated at the foot of the northern mountainside of the Turkestan range. When full its area is 2.9 km2 and the volume is 55 million m3. The depth near the dam is 45-48m, when the water level is low this falls to 18m. This reservoir is situated in the Istravshanskaya depression at an altitude of 1,165 m above sea level. The main source of water is the small river Kattasay which rises in the Turkestan range. This waterbody is oligotrophic. An abundance of spring rains with mudflows is typical for this area. This area has a damp climate, warm summers and mild winter. The average annual temperature is not more than 11oC. Precipitation reaches 400 mm a year. Soils are typically sierozems. Daganasay and Kattasay Reservoirs are located on a flyway of birds which use the reservoirs for resting and feeding during spring and autumn. The ecological conditions (absence of disturbance, plenty of food, mild climate) attract waterfowl, sandpipers, waders, herons and allies for wintering.
