NOTE:
1. 2013-2015 data are unchanged.
2. Reason for the changes in the data in 2016, 2017; Within the scope of the “Determination of Türkiye’s Water Budget Project”
under the activities of the Hydrology Specialised Committee within the Ministry of Agriculture and Forestry, Türkiye’s areal
average precipitation, surface and groundwater potential and evapotranspiration values are updated. “Türkiye’s Surface Water
Potential Project” study was started in September 2014 and completed by the end of 2015 for 25 basins of Türkiye by the Ge-
neral Directorate of State Hydraulic Works (SHW) by determining 401 AGIs located in the main streams, tributaries and basin
outlets that can represent the basin and have a period of 1981-2010, and the results obtained as a result of the said project
study are given in the table for the years 2016 and 2017.
3. As a result of the completed basin master plan studies, the data was updated in 2018.
4. The data for the year 2022 were determined within the scope of the “Basin Water Potential Determination Work”, which was
tendered in 2022 and completed in 2023. The main data source of the work carried out within this framework was the Basin
Master Plans completed by SHW and the Drought Management Plans and Sectoral Water Allocation Plans completed and/or
ongoing by the General Directorate of Water Management (SYGM).
5. National Basin Coding has been used.
(*) Fırat River mainstream annual flow is 31.61 km (2013-2015), 30.64 km (2016,2017), 31.13 km (2018).
