RaportInterpretation of resultsTo assess the state of Drini i Bardhe river sub-basins, it is considered the samemethodology by analysing the monitoring (analyses) data from the beginning to the endof water stream. In the rest of this report, an interpretation of Annual Average Values 43(AAV) will be presented as graphs, for each parameter, and each river of the Drini i Bardhebasin.The dissolved oxygen (O2 dissolved) – It consistently stands in considerable values alongthis river course (basin) where the values have varied from 6.55 mg/l to 13.12 mg/l in 2007.The values in 2008 were from 5.8 mg/l to 14.64 mg/L. The year 2009 shows a shift in themaximum value for dissolved oxygen that is 12.69 mg/L16141210mg/l86420BurimZllakuqanRadavcKlineGjonajVermiceSiqeveKlineG.RugovesDalje teqytetitKralanDeçanJasiqUra eterziveVolljakXerxeZhdrellaBuqallPiarnePrevallVllashnjeBurim Drini i Bardhe Klina Lumbardhi iPejesLumbardhi iDeçanitEreniku Mirusha Rimnik Toplluha Lumbardhi IPrizrenitViti 2007 Viti 2008 Viti 2009Figure 5: Dissolved oxygen in the Drini i Bardhë river basinThe biochemical oxygen demand (BOD5) – in the measuring station in Vllashnje –Lumëbardhi i Prizrenit, the highest registered values are 6.74 mg/l for 2007, while in2008 the maximum value reaches 7.22 mg/l in Xerxe (Rimnik river).

In 2007, the annual maximum values of this parameter are registeredin the Drini i Bardhe River (Location Gjonaj) and in Rimnik River (location Xerxe) with~0.15 mg/L, while in 2008 the annual maximum values are registered in the Erenik River(location to the Terzive Bridge). During the serial measurements maximal value of thisparameter was 0.94 mg/L in Erenik River (location to the Terzive Bridge) in August. Inthis case, the water amount was minimal in comparison with previous annual period. Theyears 2009 and 2008 show a sharp increase of this parameter in comparison with 2007,where at the Rimnik River (samples taken in Xerxe), results with a maximum annualvalue of 0633 mg/L, which is simultaneously the highest average value recorded in thisbasin for these three years.© Agjencia e Kosoves per Mbrojtjen e Mjedisit87120
