Lat attempt at releases in NW WA where tanked when the WDFW & NWTF walked away after the local organic farmers raised concerns ... 
Which I might add those concerns were valid. NWTF "experts" told WDFW that they were premature with Easterns in the 90's and to release Rio's into western Washington instead because they did so well in southern Oregon. Yeah like Whatcom County and Roseburg, Oregon are so similar.
Rio introductions up north would have been a huge mistake with nuisance problems to certainly follow on those small organic farms. Easterns on the other hand could have been sold to those opposed with a little work and education, as they would have posed no problems whatsoever. It would have also resurrected the Eastern release program.
In a rush to get something to hunt up there, coupled with the opinions of a couple NWTF biologists and NWTF regional community organizers that didn't know what they were talking about, it unfortunately gave WDFW what they wanted, an excuse to say no.
