Hydrology and Hydrographic Network 
Uzbekistan is located between two of the greatest rivers of Central Asia; the Amu-Darya and 
Syr-Darya (UzAssystem, 2021a). As Uzbekistan is landlocked, water resources of the country 
consist of surface runoff of Amu-darya & Syr-darya river contributing approximately 55%, runoff 
of small rivers contributing 33%, underground waters contributing around 10% and 
collector/drainage waters contributing (2%). All watercourses and water bodies of Uzbekistan 
are attributed to the Aral Sea basin. (Third National Communications, UNFCCC, 2016). 
According to the Annual Report of Surface Water Quality in the Territory of Uzhydromet (2018), 
the main watercourse in Bukhara region is Zarafshan River. According to hydrographic 
features, it belongs to the Amu-Darya river basin. The catchment of Zarafshan River is located 
in the most elevated part of the Pamir-Alai mountain system with eternal snow and glaciation, 
therefore, the supply of the river is fed by glacial-snow with maximum flow occurring in July-
August. The Kuyumazar reservoir is constructed in the lower reaches of Zarafshan. This reservoir 
feeds on the discharge water of the Amubukhar canal. The main power source of the 
Kuyumazar reservoir discharges from the Amubukhar canal, which supplies water to Amu 
Darya river. Additionally, water from Zarafshan river comes to reservoir through the supply 
canal during the flood and non-vegetation period. The Kuyumazar reservoir has fishery 
importance. 
The chemical composition of Zarafshan River is formed under the influence of wastewater from 
industrial enterprises in Samarkand, Kattakurgan, Navoi and agricultural areas. Irrigation 
farming is the largest water consumer in the region.
According to the Hydrologic and Hydraulic Report prepared by UzAssystem for the Project, 
(UzAssystem, 2021b) the main hydrographic infrastructure of the Bukhara irrigation canal 
network includes the Amu-Bukhara-II pumping station, the Amu-Karakul canal as well as the 
Kuyi-Mazar. Tudakul and Shurkul reservoirs. which are used for the irrigation water 
management. This irrigation network is complemented by an extensive drainage system with 
six major “Drainage Water Collectors” (DWC)-Central, North, Parallel, Tashkuduk, Parsankul 
and Ogitma.
The main collectors in the region are the West Romitan, North Bukhara, Dengizkul, Main 
Karakul, Parallel and Central Bukhara collectors. The drainage not only removes the surplus 
water from the irrigated fields but also the leached salts, fertilizers and pesticides. The greatest 
contribution to the state of the watercourse is organochlorine pesticides, as well as phenols (3 
MPC), copper and chromium (2 MPC). In terms of water pollution index (WPI), the Annual 
Report of Surface Water Quality in the Territory of Uzhydromet (2018) reports that the water 
quality of Zarafshan River in Bukhara region belongs to the III class of moderately polluted 
waters.

Groundwater 
Groundwater resources in the country is used mainly for drinking & municipal water supply. 
Small portion of this is used for land irrigation (Third National Communications, UNFCCC, 2016). 
Hydrogeological conditions are characterized by the development of groundwater horizon at 
a depth of 2.1 to 2.9 m. The groundwater level reaches its maximum in the months of April and 
May and reaches its the minimum in the months of December and January.
