Dzoraget River Piped 11% Because of SHPPs
The Dzoraget River is one of the largest tributaries to the Debed River; its length is 67 km. It rises from the slopes of Javakhq mountain range. The catchment area of Dzoraget is 1460 sq. km. The largest tributary is Tashir River, which rises from the slopes of Virahayots mountain range, flows through Lori highlands and flows into Dzoraget in a distance of 28 km from the mouth. In the upper current the river joins Gargar tributary, afterwards Dzoraget joins the Pambak River and originates the Debed River.
The river has east-south-east direction and is close to Bazum mountain range, therefore longer tributaries join on the left, for example, Sevaberd, Tashir, Urut, Hovnanajur, out of which the first two have more water. Right-wing tributaries are Chqnagh and Gargar.
The river feeds variously: 53.2% accounts for snow and rain, while 46.8% accounts for underground waters. The last indicator is the highest in the Debed basin.
As of 1 October 2013, under the licenses issued by Public Services Regulatory Committee, the following SHPPs are constructed on this river:
- “Katnarat” SHPP operated by “VANSHAYN” LLC, derivation length – 3450 meters,
- “Dzoraget-5” SHPP operated by “Hazar u Mek” LLC, derivation length – 1850 meters,
- “Dzoraget-5” SHPP operated by “VRB Concern” LLC, derivation length – 2360 meters,
The SHPPs pipe a total river area of 7660 meters, which makes up 11.432836% of the river.
Under EcoLur’s Ecological Risk Model, this indicator is within standards.
