Granby is forecast for a "small spill" in July and I expect other reservoirs are in the same situation. If I were to guess, we'll see Sur for a few days if there's a rapid warm-up, but not if it's a slow burn. The reason for no Sur this year is less due to reservoir storage and more due to a roughly average snow pack in terms of SWE. The high "% average" simply reflects a late runoff, not an above-average water supply.
With that said, I was pleasantly surprised by the Glenwood wave at about 9500 cfs (only an hour from Sur). The right side is an all-dav wave at that level albeit steeper than sweet Sur. As I recall, the more the better at Glenwood and I wouldn't be surprised to see protracted levels above 10k throughout June.
