         Temperature: Floating Weekly Average Willow Creek @ 3 Locations 1999 | 
     
 
 
    | 
   Caption:  The floating weekly average water temperature of Willow Creek at three sites in 1999 is shown above. The 1999 maximum weekly average temperature (MWAT) remained below stressful for coho (16.8 C) except just above the mouth at the USFS downstream migrant trap where that temperature was exceeded briefly. This threshold represents suitability for coho salmon according to Welsh et al. (2001). See Info Links for more information. Data provided by Six Rivers National Forest.
