In order to reduce the negative effect of lower water temperature released from the intake to the salmon in the downstream of the river, a multi-level intake was adopted in Glen Canyon Dam. Based on three-dimensional numerical model EFDC, this article simulated the water temperature under different discharge and open combination, obtained the effect law of discharge and open combination on temperature of water released. The results show that the temperature released increases slightly with the increase of the single diversion flow rate. The effect on the temperature released is very small when the intake opens in different combinations.
