To improve the quality of water from water supply source and to establish the management plan of dead plants in flood control reservoir around Juam Lake, the effect of water quality by dead plant in column with passing time was investigated. In column test, the amounts of release by Carex dimorpholepis were 7,893-7,917 mg m-² month-¹ COD, 2,711-2,816 mg m-² month-¹ T-N and 342-547 mg m-² month-¹ T-P. The amounts of release by Miscanthus sacchariflorus were 6,487-6,507 mg m-² COD, 1,813-1,868 mg m-² T-N and 226-405 mg m-² month-¹ T-P in column. Therefore, the release of COD, T-N and T-P by Carex dimorpholepis were more than those by Miscanthus sacchariflorus Benth in column.
