The article doesn't help much for understanding what will change from the current situation - and we wonder why papers are going out of business. Based on what I've heard from people who know people who understand this, it will result in increased flows on the Colorado and Fraser. As best I can understand, the Front Range owns massive water rights in this area, enough to dry up the Fraser. Prior to this proposal they have no restrictions on what they call pull, except their current, already high, allotment. This proposal at least guarantees a certain amount of water will be left on the Western slope and minimum yearly releases in certain areas.
It would be great to get a detailed description of the salient points from someone who understands though.
The very fact that they're willing to release water to coincide with the sometimes annual Gore race strikes me as great progress in itself for boaters.
