Abstract: During the period of the impoundment of Three Gorges Reservoir, there was a significant water level drop downstream reservoir in middle Yangtze River. It has exerted an obvious influence on the throughput of Dongting Lake. Based on a well verified numerical model of the river-lake nets, the throughput of Dongting Lake influenced by the Three Gorges Reservoir during the period of impoundment was analyzed in this article, by employing the inflow and outflow of Three Gorges Reservoir from 2009 to 2012 as the boundaries. The results show that, because of the impoundment, the inflow and outflow of the Dongting Lake has been seriously reduced, combined by the water level drop in the lake. At the same time, the ability to outthrow the water from Dongting Lake to Yangtze River has been slightly strengthen. It will seriously worsen the water resource and the environment in Dongting Lake during dry season
