Water level is critical to the flood control， water supply as well as environmental characteristics and ecological attributes of shallow lakes.Wind is the key factor on the determination of water level and yet the relationship between them is not fully illustrated.Therefore，a field observation was conducted in Taihu lake to obtain the typical wind period lasting for 24 hours with directions of SE and NE as well as the synchronous water level data at 6 level stations around the lakes.Based on this the relation between typical wind and water level was estimated.Results indicate that the relevance of water level stations mainly depends on their location.The Maximal information coefficient（MIC） between two stations in the north and three stations in the south are all higher than 0.80.The water level distribution governed by SE wind direction was related with wind speed.When the wind speed equals 9m/s，the water level increases with the increment of fetch，while the trend was opposite with wind speed of 5m/s.The water level distribution governed by NE wind direction rises along with the increment of fetch regardless of wind speed.A positive relation between disparity in water level around the lake is observed with same static water level，while the relation between water depth and disparity in water level becomes negative if the wind speeds are the same.
