Hydroecological research station in Ile river delta Monitoring base station «Arkhar» Hydroecological station was based in the second half of the year 1986 in settlement Arkhar of Almaty region in Ile river delta for experimental hydroecological and meteorological monitoring. Hydrological monitoring in Ili river delta was carried out by the network of 8 hydrometeostations of Goskomgidromet of KazSSR. These stations mainly showed mode of runoff at the inflow and outflow point of delta. Poorly studied was the middle part of the delta, especially Zhidelin area which is characterized by complicated system of watercourses. In this connection Institute of Geography AN Kaz SSR, nowadays Institute of geography JSC “National Scientific and Technological Holding Company “Parasat” organized hydrometric monitoring at 8 points, from which 7 at watercourses (channels) and 1 surface point at the lake Asaubai (fig. 1). At the 5 points measurements of runoff and surface mode monitoring were conducted simultaneously, 4 points from them in the not freezing-over period were equipped with recorders of water level ГР-38 and at the point of channel Zhideli of the settlement Arkhar, was placed recorder of a water level "Valdai". Measurements of runoff were carried out by standard hydrological devices and equipment applied in the system of hydro-meteo-service.
