   Caption:  This temperature stress graph shows a series of weeks during summer and early fall 1991 and how many out of the 168 hours in each week the water temperature was stressful for salmonids (20 C/68 F).  Temperature stress is much more acute at Weitchpec than at Burnt Ranch (see previous Chart). Based on U.S.Fish and Wildlife Service data provided by Paul Zedonis. See Info Links for more information.
