Benthic macroinvertebrates are bottom dwelling organisms without backbones, which are visible to the eye without use of a microscope they are living in all types of aquatic environment like rivers, streams, ponds, lakes etc. Most of the aquatic insects live in side water in their aquatic larval stages. They often found on, under or around rocks, vegetation, logs and sticks or burrowed into the bottom sand and sediments. In this regard’s benthic macroinvertebrate and aquatic insects of Chalbardi lakes, Bhadrawati were studied. Benthic macroinvertebrates are commonly used as indicators of the biological condition of waterbodies. Macroinvertebrates play crucial role in aquatic ecosystem as they are major food sources for higher trophic levels. Benthic Macroinvertebrates were studied by viewing their potential degree of pollution. In lake side areas the aquatic organisms like coleopteran, Dytiscidae (Predaceous diving beetle Cybister spp.), Gyrinidae (Whirling beetles) and aquatic hemipterans, Belostomidae (Giant Water bug), Nepidae (Water scorpion), hydrometra, Rantara and others were found. The occurance of dipteran larvae like Chironomus larvae in the lake sediments point out towards the presence of organic pollution in the lake basin. From the sediments of the lake as well as from submerged plants the molluscan species were recorded.
