1 Analytical Tools for Decision Support by the Example of the Chu-Talas Basin Ye.Sakhvaeva, Kyrgyzstan Bishkek September 2016

2 Chu-Talas River Basins Chu and Talas Rivers (Talas River is a tributary of the Chu River, a tributary of the Syr-Darya River) Snow- and glacier-fed rivers, W (Chu River) 6.6 km3 (5.5 is formed in the territory of Kyrgyzstan); W (Talas River) 1.6 (0.94 km3 in the territory of the Republic of Kazakhstan) Sharing of water resources is based on the Statutes on Sharing the Flow in the Chu and Talas River basins (1983) and the Protocol dated February 18, 1985 the principle of equal support of irrigated lands The first document regulates the use of water resources in the Chu River basin in general, the second in the sections of the Chu River stem stream The sharable water resources the Chu River amount to 6,640.0 million m3, of which 1,777 million m3 are constituted by return waters The share of the Republic of Kazakhstan makes 2,790.0 million m3 (42%); share of the Kyrgyz Republic makes 3,850.0 million m3 (58%). According to the Protocol dated February 18, 1985 : water resources from the Chu River stem stream shall be allocated as follows: Kazakhstan and Kyrgyzstan 1,810.0 million m3 Talas River Under these documents, the share of the Kyrgyz Republic in the water resources of the Talas River is =829 million m3; share of the Republic of Kazakhstan is 695 million m3

3 Relations after 1991 Interagency Protocols on construction and repair works at the Kyrgyz water facilities of interstate status since 1996 Bilateral intergovernmental agreement on the use of interstate water facilities on the Chu and Talas Rivers dated January 21, 2000: The list of interstate facilities The agreement on sharing operational costs between both Parties proportionally to the volume of water received Establishment of a parity Commission with the permanent Secretariat, etc. A Commission Regulation has been adopted; meetings are held biyearly in the form of sessions Two Co-chairpersons; 21 meetings of the Commission and more than 30 meeting of the joint Secretariat have been held in the period from 2006 to 2016 The website of the Commission: chui.at.kg

4 Activities of the Secretariat Four Working Groups: institutional development (А), sharing of water resource (В), maintenance of water facilities (С) environmental issues (D), ADB support The Working Group B (headed by V.Shablovskiy) has designed a SOFTWARE PACKAGE TO PLAN AND ACCOUNT FOR ALLOCATION OF WATER RESOURCES OF TALAS RIVER downstream of the Kirov reservoir; the activities are carried out independently by the staff of Talas Basin Water Management Authority of the Kyrgyz Republic and Chu-Talas Water Basin Inspection of the Kyrgyz Republic. The software package is used to: Calculate various options of the Water Sharing Schedule for the vegetation period for different predicted values of irrigation sources water content and regimes of water intake in Kazakhstan and Kyrgyzstan. Starting from 2008, the option agreed by the Kazakh and Kyrgyz parties is approved as a Schedule for Interstate Sharing of Water Resources of the Talas River Basin. During the vegetation period, the Water Sharing Schedule performance indicators are regularly estimated, the water sharing results are analyzed and discussed. Currently, the objective is to make adjustments based on the accumulated runoff database

5 Water supply to Kazakhstan through Gauging Station #5 Lower Zone Kyrgy zstan Middle Zone Kyrgyzstan Upper Zone Kyrgyzstan Talas River Basin Talas River Besh-Tash River Urmaral River ACTIVE RUNOFF Data from 4 gauging stations of Hydrometeorology and Environmental Monitoring Service + water intake of Kyrgyzstan + lateral inflow (unmeasured tributaries + outcrop waters - losses) WATER RESERVES IN THE RESERVOIR AT THE BEGINNING OF THE VEGETATION PERIOD Kumushtak River SHARABLE WATER RESOURCES KIROV RESERVOIR Share of Kazakhstan (gauging station #5) Share of Kyrgyzstan (water intake in upper, middle and lower zones) Gauging Station #5 Kazakhstan Water intake by the Kyrgyz users Gauging stations of KyrgyzHydroMeteoService (Hydrometeorology and Environmental Monitoring Service)

6 Chu River Basin Ortotokoy Reservoir is located beyond the water sharing zone Different categories of water users (energy sector, agricultural producers) The water balance parameters for the sections of the Chu River course are not adequately studied. There is a zone of water outcrop and a zone of water losses; the parameters of these areas for the decades of vegetation period under the current conditions are defined in general terms only. The network of balance gauging stations along the the Chu River course is destroyed.

7 ORTOTOKOY RESERVOIR Scheme of Formation and Allocation of Water Resources of the Chu River Basin Gauging Station, Chon-Kemin River mouth Dam, Bystrov HPP EBCC Dam Gauging Station Chu-Tokmak Water outcrop at the section Gauging Station Chu-Tokmak - WBCC Dam Water outcrop at the section WBCC Dam - Gauging Station Chu-Milyanfan Gauging Station Chu-Milyanfan Gauging Station Terek- John Gauging Station Dzhil -Aryk Bypass Chu Canal - I East Big Chu Canal (EBCC) Bypass Chu Canal - II Krasnaya River West Big Chu Canal (WBCC) WBCC Dam Zone of Losses Water Intakes by Kazakhstan Water Intakes by Kyrgyzstan Zone of Outcrop Chumysh Dam Georgievskiy Canal Atbashinskiy Canal

8 Calculations for the Water Sharing Schedule are carried out for the forthcoming vegetation period (taking into account the projected water content in the basin sources; actual water storage in the Ortotokoy Reservoir at the beginning of the vegetation period; flow capacity of the transportation route sections; approved limits of water sharing by section). During the vegetation period, the Water Sharing Schedule performance indicators are estimated on a ten-day basis Is operated by the Chu Basin Water Management Authority of the Kyrgyz Republic

9 As of today, operational control of the water-intake facilities at the headworks of West Big Chu Canal, East Big Chu Canal and Chumysh hydrosystem has been automated under the SDC-2 Project Recently, programs have been designed to transfer the results of automatic recording of water supply parameters to the database of the software complex for the interstate sharing of water resources of the Chu River Basin for being further used as a source of information 15 points

10 ADVANTAGES Regarding volume of the Chu River basin water resources subject to allocation Regarding the actual water supply to the large waterintake facilities supplying the major volume of water to the users In future, it is planned to use the automatically recorded data to estimate the parameters of water loss or outcrop along the Chu River course that will improve the planning quality for water resources allocation

11 Aspara River Basin The AUTOMATED SYSTEM FOR ACCOUNTING ALLOCATION OF WATER RESOURCES OF ASPARA TRANSBOUNDARY RIVER (water sharing between the Republic of Kazakhstan and the Kyrgyz Republic ) has been designed with the support of USAID (CAREC) Authors: V. Shablovskiy, Ye. Polyak (Kyrgyz Research Institute of Irrigation) There is no accurate and reliable accounting for incoming water resources gauging station does not work Accounting for water allocation between users is not accurate enough There is no possibility to apply an on-line system to exchange information on the basin water resources received and allocated

12 Scheme of water sharing at the Aspara River Control Station, Kyrgyz Republic Shared resources W= Q1+ Q2+ Q3. Water intake by Kyrgyzstan Q4 Water intake by Kazakhstan Q2+ Q3 Water discharge into the river course Q5 = Q1 - Q4 Control Station, Republic of Kazakhstan

13 АС: Existing gauging stations are equipped with tools for automatic control and recording of water supply; The recorded data are transmitted via cable lines to the appropriate control station (marked by dashed lines) ; Control stations (Kyrgyz and Kazakh) are equipped with computers making it possible to: input and decode records on the regime of water supply from the serviced gauging stations; maintain database on the actual water supply regimes at the gauging stations; display information about the intakes at the control points; generate reporting documents with intake totals for different periods of time; Information on the partner country s intakes is communicated via radio channel by using radio modems operating in the license-free ISM band.

14 Cooperation in the framework of the Chu-Talas Water Commission With the GIZ support Based on the database (CAREWEB SDC SIC-ICWC), a database for the Chu and Talas Rivers has been designed it is necessary to support it With the SDC support (IMOMO), a quarterly ИГБЛ has been designed for the Chu River: section schemes, water resources, actual water intake - long-term annual average data on reservoirs regimes and river flow; data viewing is accessible for a limited range of water management authorities of the both Parties Regular review at the meetings of the Chu-Talas Water Commission and Secretariat it was decided to work on ИГБЛ for the Talas River
