This is the first of two reports that document water quality and set water quality objectives for the lower Columbia River from the Hugh Keeleyside Dam to the U.S. border. To complete this study, the lower Columbia River was divided into two reaches: from the dam to Birchbank, and from Birchbank to the border. The reach of the lower Columbia River sub-basin covered in this first report extends for 27.5 km from the Hugh Keenleyside Dam to Birchbank. The Keenleyside Dam at the upper end of this reach is approximately 700 km downstream from the headwater source of the Columbia River and approximately 60 m upstream from the B.C.-Washington border. The purpose of this report is to examine the water quality of this reach, as well as input from the Kootenay River to develop water quality objectives.
