Caption: The floating weekly average water temperature of lower Rattlesnake Creek is shown above for the years 1991-1992. Water temperatures in lower Rattlesnake Creek were not optimal for salmonids throughout the summer in both years. Although the northern part of the Rattlesnake watershed was burned in the 1987 Fires, warming is probably more owing to past flood damage (see Picture #2). The maximum weekly average temperature (MWAT) exceeded the threshold for suitability for coho salmon according to Welsh et al. (2001). Data provided by Shasta Trinity National Forest. see Info Links for more information.
