Аннотация:Data on the Ruza and Mozhaisk reservoirs are used to analyze the applicability of different sampling
methods and bioindication systems for rapid water quality assessment. The collected data were analyzed
with the use of twelve biotic indices and their modifications. The mean water quality estimate in the coastal
zones of both reservoirs varied from “moderate” to “good” and corresponded to α-mesosaprobic zone. The
best performance in saprobity assessment was demonstrated by Pantle–Buck index modified by M.V. Chertoprud
in the coastal zone and Balushkina index in soft soils in the central zones of the reservoirs. It is proposed
to extend the number of indicator taxa in Pantle–Buck index modified by M.V. Chertoprud by incorporating
taxa typical of soft soils, in particular, Chironomid larvae from Chironomus plumosus group. Recommendations
are given for carrying out express-monitoring of the state of reservoirs.
