Area Middle Trinity
Topic Temperature: MWAT at Many Middle Trinity Sites, by Year 1991-1998
 
Caption:  This Chart shows maximum floating weekly average temperature (MWAT) for each site in the Middle Trinity sub-basin with available data in the years 1991-1998. Sites are grouped by stream and are listed in upstream order. MWATs in upper Little Creek and middle Reading Creek increased 5C between 1996 and 1997, potentially reflecting changes in width to depth ratios caused by debris torrents in the January 1997 storm. 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 the Institute for Forest and Watershed Management at Humboldt State University, which compiled a regional database from many sources.
