Five lakes were studied for morphometric features and for the distribution pattern of macro-
phytic vegetation in Nainital district. Eleven macrophytic communities/stands were found to occur in these alakes. No community was observed in more than one lake. Potamoge-
ton pectinatus was found to be limited to night altitude lakes only while Ceratophyllum demersum, Chara sp., Cyperus sp. and Polygonum natans were limited to relatively low altitude lakes. Hydrilla verticillata had a wide ecological amplitude as it was found both altitude as well as in low altitude lakes. Submerged, emergent and floating macrophytic species exhibited a biomass ratio of 84:13:3 among these lakes. It was noted that submer-
ged and pure stands of any macrophytic species had greater biomass compared to those of mixed-species stands. Clearer lakes were found to have greater biomass density com-
parison to the turnid lakes. P. pectinatus may serve as an indicator for silting rate while the absence of Charas sp. may indicate relative eutrophication.
