Abstract In this study, we investigated the nature of phosphate phase present in sediment of Lake Dang. The phosphate speciation was determined by sequential extraction method. The concentration of phosphate in solution was measured by the ammonium molybdate method with ascorbic acid as the reducing agent. Water and sediment (surface and bottom) were sampled at eight points around the lake by taking into account activities around the lake during dry and rainy seasons. The results showed five forms of phosphorus presents in the sediments. The rank order obtained was Res-P
