How is Türkiye's water?
Short answer
Last water year, rain over Türkiye was 117% of the 1991–2020 normal (usual; CHIRPS, data through September 2026).
Reporting hydropower dams are 48.8% full on average (87 dams, EPİAŞ, 6 November 2026).
Numbers are the same as on the Turkish pages; this page is a translation.
Su Haritası brings together Türkiye's public water data (basins, dams, rain, groundwater, lakes, rivers, historic fountains) and its water law. The English and Arabic versions cover the "Türkiye's water" pages and the tools for finding water and preparing for drought; the tools on well permits, fines and letters to authorities are in Turkish.
Finding water, preparing for drought
Each tool works for your village, with its source and date.
This is an estimate; it does not guarantee that water will be found on your land. A drilling decision requires an on-site geological survey.
- Water sources nearbySprings, fountains, wells, ponds and dams mapped within 5 km of your village.
- Where water gathersValley floors and hollows where rain gathers because of the shape of the land.
- Drought statusRain over your village in the last 1, 3, 6 and 12 months compared with normal.
- Rainwater tankHow much water your roof collects, and the tank size for the dry months.
- Water my field needsMonth-by-month water use of your crop and the rain over your village.
- What can I grow?Crops that need the least irrigation in a dry year, and water-saving irrigation.
- Saving water at homeHow many tonnes a month each change saves, and at least how many lira.
- Green in the dry seasonPlaces that stay greener than their surroundings in the driest months.
