Abstract The effectiveness of a previously developed bottom trap technology to capture endogenous pollutants were examined in Lake Chaohu. Sediment pollutants could be effectively collected into the bottom trap, including algae (chlorophyll a), organic matter, total nitrogen and total phosphorus, and the collection efficiency presented obvious temporal and spatial differences. The bottom trap could collect much more sediment pollutants in the western part of Lake Chaohu than in the center of the lake. The sedimentation rates were higher in spring and summer than in autumn and winter. The annual-averaged collection of chlorophyll a, organic matter, total nitrogen and total phosphorus for the trap per unit area varied between 2.37~15.28g/m², 8.96~21.82kg/m², 0.78~1.88kg/m² and 0.30~0.93kg/m², respectively. Due to the lake current, wind wave, and the distribution and thickness of internal pollutants in Lake Chaohu, six bottom traps with length of 11~33km along the lake current accumulation areas, and seven bottom traps at the estuaries of seven main inflowing estuaries are recommended in Lake Chaohu. In addition, the existing shipping channels are suggested to be modified to bottom traps by deepening. This study provides new governance and management methods for the control of internal loads in Lake Chaohu.

Key words： internal loadings bottom trap wind wave lake current Lake Chaohu
