The study analyzed the physico-chemical quality of water and the resident phytoplankton community, and evaluated the water trophic status in So-ok stream flowing into Daechung lake from October 2007 to July 2008. Algal blooming by cyanophytes and diatoms continued throughout the year, with Microcystis aeruginosa and Aulacoseira granulata being prevalent. Ten taxa that are indicators of polluted water, including Oscillatoria limosa appeared. Results based on (Trophic status index) TSI and (Lake trophic status index) LTSI evaluations of water quality status indicated mesotrophication.
