Caption: The Chart above shows the number of hours in the week that Klamath River water temperatures exceeded stressful for salmonids (>20 C) during late summer in 1995 at Blue Creek. The automated temperature sensing device was not deployed until the first week in August (32 = 32nd week). Temperature stress for salmonids is derived from McCullough (1999) who noted that growth for all species ceased above that temperature. Data collected by U.S. Fish and Wildlife Service Arcata Field Office. See Info Links for more information.
