The present study was conducted for the study on the community stucture of the benthic macroinvertebrates and the water quality in Smchun-impoundement based on the biological parameters. The survey area induced eight sites in Samchun-impoundment and the study was carried out from September 1997 to July 1998. The result are as follows; (1) Benthic macroinvertebrates are composed of 74 species including 64 genera, 41 families, 13 orders, 5 classes in three phyla. (2) Hemiptera and Ephemeroptera were dominant taxa in this area. (3) The diversity indices ranged from 2.022 to 2.519 depending on the site. (4) The water quality criteria was investigated as α- mesosaprobic with Group Pollution Index(GPI) 1.91.
