Abstract : Water quality characteristics, MPN index/100ml, and zooplankton of sacred Devak stream, Udhampur
were analyzed during February, 2010 to January, 2011. Various water quality parameters showed a well marked
seasonal variation including MPN index/100 ml which remained above 240 during all the observations. Zooplanktons
comprising of 46 species showed qualitative dominance of protozoa (33 species) followed by rotifera (7 species),
annelida (2 species) and insecta (1 species), water nematoda, turbellaria (1 species) and cysts. Zooplankton was
qualitatively and quantitatively poor/absent during monsoon floods (June to September) and was diversified and rich
during February to May. Comparison of water utility parameters and MPN count/100 ml with national and international
agencies suggested that water of this stream was not fit for consumption.
