Miller Walker Creek research leads to publication. The University of Washington researchers, with whom WRIAA 9 has partnered for the last several years, published new findings yesterday that isolate the specific chemical in tires causing mortality in coho salmon during rain events. Read the Seattle Times article or the more complex Science publication below; the study is broader than the Miller Walker basin, but research from Miller Walker is included in the study. Matt Goerhring from WRIA 9 says that “Unfortunately the chemical – a common tire preservative – appears to be used in all tires. However, the research hopefully paves the way for development of a salmon safe tire in the future.”
