another issue with the lake WA run is that by the time that adult collection takes place the time for recreation has long since passed, with the adult capture taking place from Sept-Nov there is no way to insure egg take before the sport/tribal fisheries. Also something else to take into consideration is that its estimated that 40 to 60 % of the natural production takes place in the lowest part of the river below the collection site under I405, in addition to these factors the WDFW staff has to allow for safe passage for wild cedar river CK and CO which have a similar run timing to the SO, so at times trapping the remaining 40 to 60% of the run becomes more difficult.
