Caption: The Chart above shows the number of hours in the week that water temperatures exceeded stressful levels for salmon and steelhead on the Klamath River just above the confluence with the Salmon River in 1996. The stressful limit for juvenile salmonids used is 20 degrees C (68 F). The week of the year is preceded by the year (9624 = 24th week of 1996 = 1st week in June). Water temperatures became chronically stressful in the last week in June in 1996 and remained stressful for more than one half the 168 hours in each week through the first week in September in 1996. Data collected by the Karuk Tribe. See Info Links for more information.
