         Temperature:  MWAT at Many Hayfork Sites, by Year 1990-1998 | 
     
 
 
    | 
   Caption:  This Chart shows maximum floating weekly average temperature (MWAT) for each site in the Hayfork Creek watershed with available data in the years 1990-1998.  Sites are grouped by stream and are listed in upstream order.  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 Info Links for more information.  Data were provided by the Institute for Forest and Watershed Management at Humboldt State University, which compiled a regional database from many sources.
