The 2015 season depends heavily upon how much water Colorado diverts in the San Luis Valley.
It does not appear we are headed for a snowpack that could overwhelm the diversion capacity of the San Luis Valley in 2015, so they could technically divert 100%, leaving us with a terrible season like 2013. Legally however, they may have serious incentive to let some through again this year, which could make for a good season like 2014.
Snowpack is not the key factor, laws and gate valves will determine the 2015 season on the Rio.
I'd think these matters would be in the public record, or maybe I don't know where to research it, water rights are a pretty heated issue in the Southwest.
