ABSTRACT
The analysis of the data of monitoring of natural waters (15 indicators) and sediments (8 indicators) reservoir of the river Oredezh (Leningrad region, Russia) was made for the period 2008-2011. Variations of the content of Mn, Fe and P in the bottom sediments were investigated in spatial-temporal aspects. The coefficients and indexes manganese pollution of bottom sediments were calculated. In result the method of environmental zonation for water-body was proposed. Ecological stability according to the obtained data were estimated, zones of ecological risk were revealed.

Keywords: ecological assessment, quality of water, sediments
