The purpose of this paper is to display the Prespa Lake accuracy quality as well as
measures for lake protection. To perform a risk assessment of surface waters pollution
before a season in 2011 it is made a monitoring on a beach and lake water quality by the
Center for Public Health and Bitola. It is also observed the health - environmental risk from
sewage works wastewater from catering-tourist facilities and sewage works in Ezerani. Due
to the great importance of the Prespa Lake as a natural lake, a control is periodically
performed on its surface water from January to October. Also regular reviews are made on
the coast, in and out of season to be able to perform proper assessment of existing risks on
its contamination. Parameters disturbance of the oxygen regime is due to the large increase
in the level of the lake which appeared large underwater movements and almost daily
rainfall, which contributed to disturbance water quality. Coliform bacteria identification in
surface indicates E. Coli presence, which is an indicator of fresh faecal contamination.
There are direct contaminants , rivers that pass through villages and collect sewages from
rural population. Also, sanitary protection zones are not respected, there is not a local
sewerage in all villages around the lake and the existing sewage-works are not maintained
and do not treat sewages to needed quality. According to the physical-chemical
parameters, the research results display that water purity ranges from class I to III and
according to bacteriological parameters from class I to II.
Keywords: Prespa lake, protection, quality, water.
