Water quality of the lower Drava River

The paper includes review and evaluation of water quality for four monitoring stations in the lower stretch of the Drava River in the Republic of Croatia – Donji Miholjac, Bistrinci, Višnjevac and Nemetin – during period of twenty-five years (1980 – 2005). The Drava River water quality has been evaluated with respect to physical-chemical, microbiological and biological water quality parameters (pH value, electrical conductivity, DOC, BOD5, COD, oxygen saturation, nitrates, nitrites, ammonium, coliform bacteria count and saprobic activity index), as well as for the group of parameters (physical-chemical, oxygen regime, nutrients, microbiological and biological parameters) with regard to the current regulations in the Republic of Croatia.
