Area Sonoma Creek
Topic Temperature: All Sonoma Creek Sites, MWAT by Year 1998-2002
Caption:  This Chart shows maximum floating weekly average temperature (MWAT) for each site in the Sonoma Creek sub-basin with available data in the years 1998-2002. Sites are grouped by stream and are listed in upstream order, beginning on the left side of the chart with the lowest Sonoma Creek Site and ending with Graham Creek listed on the far right. MWATs exceeded 17.0C at every site at least once at all but one site, and MWAT exceeded 19.0C at least once at 7 of 16. Based on a review of steelhead growth studies, Sullivan et al. (2000) found that compared to optimum temperatures, an MWAT of 17.0C reduced steelhead growth by 10%, and an MWAT of 19.0C reduced growth by 20%. See Info Links for more information. Data were provided by Sonoma Ecology Center.
