Figure 9. Comparison of short- and long-term trace-metal load estimates at four streamflow-gaging stations in the Spokane River basin, Idaho. Short-term models used records from 1999-2004. Long-term models are based on records for the periods: Enaville (1992-2004), Pinehurst, Harrison (1991-2004), and Post Falls (1991-2003). Load estimates were not made at Post Falls for 2004.
