This website lists predictions on the odds of drawing an Oregon controlled hunt tag. 

The 2014 controlled draw predictions are now available.  Use the menu bar on the left to find the hunt you are interested in.  If you should spot a discrepancy, please send me an email.  A new feature this year, the harvest success data has been included.

Here is a quote from a thread on Ifish talking about Oregon's controlled tag draw odds.  It is a great point and is something all of us should consider...  
"...then you also have to remember that anything that changes numbers or public perception of a hunt can totally change the accuracy of the prediction... As an example, I saw a tag last year for a unit where my wife has hunted that had a downward trend in applicants, and Ron's algorithm predicted that the trend would continue and all first-choice applicants would draw. I looked a little more and guessed that at some point people would realize that this tag was easy to draw and more people would apply. Sure enough, they did. Ron's math and the trend were right, but they can't account for the human element of changing perceptions of the hunt."
