         Temperature: Floating Weekly Avg., Brush Cr. Sites 1999 | 
     
 
 
    | 
   Caption:  This Chart shows the floating weekly average water temperature at lower and upper Brush Creek (sites BRUSH1 and BRUSH2) for the year 1999.  Brush creek warmed dramatically (2.0 to 8.5°C) as it flowed from the upper site to the lower site.  Maximum floating weekly average water temperatures (MWAT) exceeded 19.0°C at the lower sites, but did not exceed 17.0°C at the upper site.  Based on a review of steelhead growth studies, Sullivan et al. (2000) found that compared to optimum temperatures, an MWAT of 17.0°C reduced steelhead growth by 10%, and an MWAT of 19.0°C reduced growth by 20%.  See InfoLinks for more information.  Temperature data comes from automated water temperature data probes placed in the Russian River and its tributaries by the Sonoma County Water Agency (SCWA).
