In connection with that this seismic in the territory of Naryn cascade maybe has its peculiarity in cludding in the territory Toktogul reservoir before of the building of the Toktogul dam, during of the building and after accordingly was decided to consider the seismic in this space of times. The arm of the present paper is estimation seismic of the territory Toktogul reservoir for different times: before of the building of the Toktogul dam (1960)(1961)(1962)(1963)(1964)(1965)(1966)(1967)(1968)(1969)(1970)(1971)(1972)(1973), during its filling (1974)(1975)(1976)(1977)(1978)(1979)(1980) and since start it's of the uninterruptedly exploitation to present time . The territory in that located the cascade of Naryn River is considered that seismic active in the Central part of the Tien Shan. The tectonic motions are become here intensity. The presence of the large faults is complicating significantly the seismic situation of the study region.
