Ürkmez Dam (Turkish: Ürkmez Barajı )is a dam in Izmir Province, Turkey, built between 1985 and 1990. The development was backed by the Turkish State Hydraulic Works.^[1]

Ürkmez Dam is located in Seferihisar district of İzmir Province, western Turkey. Its constraction began on 12 September 1985i and completed on 12 February 1990ç^[2]

It was reported by İzSu, the Water and Sewage Authority of İzmir Metropolitan Municipality, that mid January 2024, the water occupancy rate of the dam reservoir amounted to 28.58% compared to the same time in the previous year with 39.12%.^[3]

The drinking water treatment plant was projected in 1992, and went in operation on 2 July 2004. It is operated by IzSu, the water and Sewage Authority of İzmir Metropolitan Municipality.^[4]

As long as the height of the reservoir water is more trhan 26 m (85 ft), water runs to the water purification plant without the need for pumping. When the water height drops under the 26 m (85 ft)-level, four pumps of 11 kW (15 hp) each are activated to transfer water in a pipeline of 400 mm (16 in) diameter to the water treatment plant, which is about 900 m (3,000 ft) away. The plant can supply 109 L/s (3.8 cu ft/s).^[4]
