Reddit mentions of Complete Angler's Guide to Oregon

Check out this book: Complete Angler's Guide to Oregon

There is some seriously great information in there about forgotten/locals-only fishing spots throughout the state that you might not be able to find any information on from the internet. There is a sizable chunk of the book available for free from google books, but it's definitely worth the purchase.

I've also found that so long as you're willing to put a little hike in, all the rivers or lakes in Oregon are pretty easy to find solitude on. Pretty amazing how easy it is to get away from the crowds, as long as you're ready to walk.
