Good article Dave. Nitrogen supersaturation occurs when air is forced into the water under pressure. Breaking up the flow at the base of the dam prevents pressure, and structures to accomplish this were installed several years ago, so supersaturation is not the issue it once was. Spill has been working - hence the large number of returning salmon the past several years prior to this year. So far this year, because spill was curtailed in 2001 due to low flow (way lower than this year by the way), springers have returned at less than half their predicted rate, and fall limits have already been curtailed (one king instead of 2, 2 total instead of 3 as we had last year). All because of curtailed spill. So guess what, we can count on more season and limit reductions in a couple more years. Thanks George, hope this gets you the votes of your energy buddies, you shure lost mine
