Site description The IBA is a closed waterbody with sandy gently sloping banks, situated 5 km to the north-west of Ashgabat in the Ruhabat district of Akhal region. The IBA includes a water reservoir and adjoining shores. The reservoir was built in 1963 in the brackish Gurtli depression and obtains its water from the Karakumdarya river which is subject to seasonal flow regulation. The waterbody is 5 km long, 3.75 km wide and 4.36 m deep on average. The maximum depth is 7m and the water surface area is 80,000 hectares, with a shoreline length of 25 km. The shores are sandy, gently sloping, without any steep cliffs. There are plantations of deciduous and coniferous trees in places. In sheltered areas thickets of reed and tamarisk can be found. There is a recreation zone on the shore, attracting more than 200,000 people a year. There are beaches, a boathouse, a recreation department of a hunters and fishing society, rest houses and sport-health complexes. Hunting on the waterbody is banned and only amateur fishing is allowed. Fish fry are released from time to time to enrich the waterbody (100,000 fry were released in 2005). The climate is a dry hot summer and rather mild winter. Precipitation is lowest in July-August, highest in March-April. There is almost no snow. The average air temperature is 0.8C in January, +30.5C in July. The frost-free period is 232 days a year.
