To identify the formed regularities of quality and hydrochemical regime of water of Velvelechay-Takhtakorpu chnnel, Takhtakorpu water reservoir and Takhtakorpu–Jeyranbatan channel, Qusarchay, Qudiyalchay, Cagacuqchay, Velvelechay rivers, it is essential to study physical, chemical and some biological characteristics of them. Depending on time and place, studying the factors (natural and anthropogenic) influencing to hydrochemical regime of water in these objects allows to evaluate the quality of them . The followings were identified as main components for the study: pH, turbidity, usual rigidity, normal mineralization, classes and groups by O.A.Alekin, interrelation of anions and cations, biogenic elements, iron, copper, aluminum, chemical demand for oxygen (CDO(bixr)), biological demand for oxygen (BDO5). The analysis have been conducted, outcomes of them were compared and final results were identified. Anthropogenic and natural impacts influencing on hydrochemical regime of water of the investigated objects were defined
