You would think that you could get the same numbers someplace but as Curt said it is not that important in the big picture. Thing to remember is most of us use 4 years for Chinook runs but that is not a bulls eye. 4 & 5 year age groups are usually the same ( give or take change ) in numbers in any given year. Also use the brood year and not the release year as guide as the fish return 4 to 5 age on brood years not release timing. So 2013 plus 4 is 2017 and 2018 will have the 350k release 4 yr olds and 5 year olds off the 3.5million. This means the 2019 will be only returns from the 350k releases.

Did I get this right?
