    | 
   Caption:  This Chart shows the floating weekly average water temperatures at Gibson Creek (site 161) for the years 1999-2001.  Maximum floating weekly average water temperatures (MWAT) exceeded 17.0°C in two of three years, but never exceeded 19.0°C.  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%.  Temperature data comes from automated water temperature data probes placed in the Russian River and its tributaries by Mendocino County Water Agency.
