Oxygen aspect of water pollution of Skadar lake, Montenegro (Yugoslavia) is considered in this paper. Water analysis data in the period of 1991-1998 were used to establish relevant parameters, oxygen saturation (%O2), and five day biochemical demind (BPK5). Those data were supplied by Hydrometeorological Institute in Podgorica, Montenegro (Yugoslavia). Measurements were taken from three places in northern part of Skadar lake, where the increased water pollution is expected, and from southeastern part of the lake, out of source of pollution directly influence. According to results from this research, there is close relation between water pollution and oxygen water balance. Parts of the Skadar lake with low water circulation are especialy susceptible (place Kamenik). In the 1991-1995 period, this phenomena is manifested with variation depending of the chosen area and year. After some improvement of water quality in the 1996-1997 period, there is noticeable increase of water pollution in 1998 at all places. Supersaturation was identified by the percentage of O2 in Skadar lake area at whole.
