The paper analyzes the current use of the Loriya Marza water resources and the priorities of their protection. We used actual data of Ministry of Emergencies of Republic of Armenia «Service on Hydro/meteorology and Active Impact on Atmosphere Phenomena» and National Statistical Service, as well as all relevant researches, reports, legislative and regulatory acts and other materials. We used mathematical statistics methods, too. The conducted investigations/observations data has provided evidences of non-uniform spatial-temporal distribution of water resources in Loria Marza. Thus, the intensive irrigation period (July-September) coincides with the summer/fall low water period. When 15-20% of the annual flow passes through the rivers. In this period, the rivers contain very small quantity of water and in the case of mandatory water abstraction, their extinction is possible at some reaches, as a result, ecological balance of the aquatic ecosystem becomes disturbed. On the other hand, reduction of the runoff is observed on the territory under study during the low water period. As a rule, this period is characterized by the highest demand for water and this requires development of the concrete methods of water resources use regulation. To use and protect water resource effectively, it is necessary to know the dynamics of the runoff within-year and spatial distribution.
