Shasta River Chinook and Coho Salmon Observations in 2013

A total of 8,021 fall run Chinook salmon (Chinook, Oncorhynchus tshawytscha) were estimated to have entered the Shasta River during the 2013 spawning season. An underwater video camera was operated in the flume of the Shasta River Fish Counting Facility (SRFCF) twenty four hours a day, seven days a week, from August 28, 2013 until December 9, 2013, when the weir sustained structural damage from ice build-up and was removed. The first Chinook was observed on September 9, 2013 and the last Chinook on December 3, 2013. KRP staff also processed a total of 512 Chinook carcasses during spawning ground surveys (of which 469 were used in fork length histograms), 65 Chinook carcasses as wash backs against the SRFCF weir (a systematic 1:10 sample), and 45 live Chinook in a trap immediately upstream of the video flume during the season.
