They have archived reports going back quite a few years if you are inclined to sift through them and see if forecasts for a particular year at all correlated with previous recreational opportunities.
Replying to my own post, there is a table in the 2016 report that summarizes the pre-season forecasts vs actual returns from 1998-2015:

From those 18 years:
8 years where the actual returns were actually somewhat close to the 50% probability forecast, including four straight years from 2011-2014.
2 years where the returns were significantly higher than the preseason forecast including the famous 2010.
8 years where the actual returns were significantly lower than the 50% preseason forecast, including the disastrous 2009 which I believe is what resulted in the Cohen Commission report. 2016 will probably get a red label in the next report as well.
It's interesting to see the 4 year dominant cycle returns of '98, '02, '06, '10, & '14 as I never really paid much attention to it. As someone noted above, the next dominant run is not until 2018.
Gazing into the crystal ball, 2017 returns are from the 2013 brood year which featured ~4-5M fish which appears to be about an average return for a non-dominant year, based on this chart.
Were there any recreational openings back in 2013? or in 2011 which also had a similar sized ~5M return? If not, then you can probably write off the upcoming season unless the forecast is significantly larger, or the returns are unexpectedly high. No comment as to how the openings might be influenced by the various special interest stakeholders.
