The Lake Chany complex, located in Western Siberia, consists of the large shallow lakes with an average depth of about 2m. The lake area fluctuates according to water level that depends closely on the amount of inflow( snow-melt) and the evaporation, since the lake complex has no outflow river. Based on NOAA/AVHRR satellite normalized difference vegetation index (NDVI) data of the ice-free periods in 2000 and 2001, we evaluated the seasonal changes in the lake area and the surroundingu vegetations of the Lake Chany complex. In late April or early May, the maximum lake area was abserved and the lake area decreased drastically until late May or early June. Then, the lake area decreased gradually from early June to late August. The lake area in August was about 70% of the maximum. Then, the area tends to increase by early October. Compared with the ground truth in August 2001, the seasonally fluctuated areas on NOAA images corresponded to the vast vegetations with several km in width of reed (Phragmites communis) stands which seem to be influenced by the inflow of snow meltwater and the growth of reeds.
