Zabol Chahnimeh reservoirs are three natural and big cavities in the south of Sistan Plain Located in South-Eastern Iran and It Includes 50 Millions square meter extent. Stored Water In These Cavities Are Used To Sistan Earth And For Providing Drink Water of Zabol And Zahedan Cities. Because of the drink and agricultural usage and for investigation of water quality of chah-nimeh reservoirs, this research has been done in one year. Methods: In this research density of Na+ ,Mg2+, Ca2+ ,Cl- ، SO42- and EC , TDS ,TH parameters have been analyzed in 9 stations, then results have been rebounded on schuler & vilcoks diagrams. Results: Results showed the quality of water in reservoirs viewpoint of drinking sited in acceptable stage and viewpoint of agricultural sited in C3S1 (average quality) stage. Discussion & conclusion: finally, if the texture of soil be light, we can use water of these reservoirs for agricultural activities.
