2 Chinook correlation (Figure 3) has been reworked by Steve 



3 Mathews and indicates an expected run of 37,000 fish in 



4 1967. This would permit a catch of 22,000 chinook while 



5 allowing an escapement of 15,000 chinook. 



6 The Chinook run to the Skagit River has been 



7 shifting in time during the past few years from a peak near 



g August 1 to a peak near August 10. This shift is shown in 



9 Figure h, where average daily catches are plotted for the 



i 



10 years 1951 through i960 and compared with the averages for i 



11 the years I96I through 1966. The I966 catches are shown ' 



12 in Figure 5 and the shift mentioned is quite obvious. It 



13 is our belief, based upon the timing of the Samish chinook 



14 run, that this shift in time is due to increased production 



15 of fall chinook from the Skagit hatchery. It can be ex- 

 Ig pected that in I967, August catches will be higher than in 

 17 1966 due to an increased hatchery plant of I963 brook chinook 

 Ig salmon. 



19 Catches in 1966 did not exceed the averages 



20 shown in Figure 4 prior to late July, indicating a very 



21 poor June and July run. Furthermore, a check of the age 



22 composition of the chinook catch showed a large number of 



23 5's and less than 4^ - 3's. During the two previous years, 



24 the percentage of 3 ' s was 10-11^. We believe that the June- 



25 July segment of the chinook run in I967 will again be below
