I have a whole binder full of info on this topic that I was fortunate to have been given. I don't have time at the moment to OCR everything into the post here (especially with a bad OCR program and photocopies to start with). It includes an extensive study on the fertilizer made by Vigoro Corp. which applied for a patent on it on January 27, 1995.

But looking over the data, OR & WA streams are in sad shape when it comes to fertile streams. A URL you can visit to give an overview:

An excerpt from this article:

"Research has indicated that between 93 and 155 carcasses per kilometer are needed to provide the maximum ecological benefit on coho streams. While Oregon’s goal for coastal coho streams is 26 fish per kilometer, only two to seven fish per kilometer were found in 1997."

When was the last time you saw that many carcasses in a the upper tribs. Not very often I'd imagine ... but I've seen streams in other regions that have these sorts of numbers and more ... just wish we had them here
