Physico-geographical characteristics
Lake Dadynskoye is located in the southeast of the Kumo-Manych depression [3] [4] , northeast of the village of Priozerskoye in the Levokumsky region [2] . It is a group of three shallow lakes (0.7 - 2 m), with a total area of 31.5 km² [4] [5] :
- Big Dadinskoe ( Dadinskoe ). Stretched from northwest to southeast. The length of the lake is 14 km, the greatest width is 4 km. Altitude - 14 m. The coastline is rugged and winding. In the water area of the lake there are many small islands.
- Small Dadynskoe ( Salty ). It is located east of the Bolshoi Dadynsky and is also elongated from the northwest to the southeast. Height above sea level - 13 m. Length - 9 km, the greatest width - 1.8 km. It has many small islands.
- South Dadinskoe ( Maksimokumskoye ). Stretched from south to north. Length - 7 km, the greatest width - 1.2 km. Height above sea level - 17 m. It has a large number of islands and peninsulas [4] [5] [6] .
The lake is surrounded by salt marshes , sometimes muddy and impassable. Solonchak soils occupy the most extensive area in the northwestern part of the coast [5] [7] . In elevated areas of the area around the lake, a cereal-wormwood xerophytic semi-desert steppe is common [4] [7] .
The power sources of the lake are melt snow waters (in spring) and precipitation (in summer) [7] , as well as artesian wells located on the coastal territory [4] . In the southern part, Dadynskoye is fed and desalinated by the waters coming from the irrigation system of the Kumo-Manych Canal [3] [5] . In dry periods, the lake dries up [4] .
Flora and fauna
Separate sections of the coastal zone of Lake Dadinskoye are occupied by dense reed beds ; grassy vegetation of the steppe plots is represented by xerophytes ( wormwood , feather grass , fescue , bluegrass , and wheat grass ) [4] .
Lakeside territory is a place of mass concentration of waterfowl and near-water birds belonging to common breeding species ( small grebe , grebe , cormorant , big bittern , yellow heron , great white heron , small white heron , gray heron , red heron , mallard , gray duck , broad-nosed , red-nosed dive , black -headed black , marsh harrier , moorhen , coot , laughter , white-winged tern , river tern ) [7] .
Of the rare species of birds there are: tea-nosed tern , red-breasted goose , black-headed laughter , belladonna , steppe kestrel , avdotka , stilt . In a small number, representatives of species that are declining in number nest on the lake: small tern , curly pelican , spoonbill , and steppe tirushka . In non-breeding time, there is a small cormorant [8] .
In the vicinity of the reservoir rare species of reptiles live - patterned snake [9] and pallase snake [10] .
