Sediments are one of the most important constituent of lacustrine ecosystems. The study was conducted to assess the physico-chemical properties of sediments of Lake Mansar. The texture of sediment was sandy loam with sand (>60%) as dominant particle size class. Organic matter varied from 1.91% - 3.45 % and is significantly related with total nitrogen, pH and moisture content. pH of sediment was mostly alkaline with average value of 7.55 0.46. Lake sediment wasmild organic and probably in a process of accumulation of organic load from catchment area due to various natural (erosion) and anthropogenic causes (tourist and construction activities). Total phosphorus was fairly high but not related to organic matter which may be contributed by the domestic discharge, community bathing and washing and agricultural run-off. Thus, environmental surveillance of lake sediments is highly recommended in order to closely monitor the quality of sediments of LakeMansar.
