The water quality was observed within the limits for drinking purposes, but there is an extensive growth of algae and higher aquatic plants in both the lakes. Total of 205 algal species were identified, comprising 43 sp. of Cyanophyta, 92 sp. Chloruphyta, 6 sp. Charophyta, 11 sp. Euglenophyta, 57 sp. of Bacillariophyta. Higher aquatic plants belonging to 31 species were also identified. Zooplanktonic fauna of both the lakes were quite different. The Cladoceran species. Ceriorlaphnia cornuta, Bosminopsis deitersi, Diaphanosoma hrachyurum and Bosmina longirostris were dominant, at Kinjhar. In Haleji lake, on the other hand Macrothrix sp., Chydorus sp., Sirnocephalus vetulus and Moina sp. were dominant.]]>APHA.,198115th Edn.,Baig, N.A. and M.Y. Khan,1976283340Baqai, I.U., V.A.
