Description During the unusually high flows experienced in the Spokane River in April - June 1997, dissolved zinc and dissolved lead consistently exceeded EPA 1995 water quality criteria by factors of 2 to 6, from above the state line in Idaho (river mile 98.7) to Riverside State Park (river mile 66.2). The zinc and lead criteria were also exceeded in a sample collected below Long Lake (river mile 33.3). Dissolved cadmium slightly exceeded criteria at the state line. Dissolved copper was not above criteria. The 1995 EPA criteria will replace current state standards in November of this year.
