Open-File Report 2011–1008
Water-quality data have been collected in the North Santiam River basin since 1998. During water year 2007, eight monitoring stations were operated throughout the basin. Streamflow data were collected at all but one of these sites. This report presents a comparison of the water-quality and streamflow data collected at each monitoring station from monitor installation through water year 2006 with the data for water year 2007. Data were compiled monthly and annually to identify extreme values by season and for entire periods of study.
