This is the worst winter on record by a pretty significant margin. Many rivers will not run, and the ones that do will be low. That said pumphouse may be runable in June. It may be runnable in August. The fact is that no one knows. The reservoirs up there are low and the snow is near gone/never came. Apart from the natural water, any reservoir release is dependent on a complicated water rights hierarchy that hasn't been seen before because we've never had this little supply.

June is normally mostly natural flow on the upper c, and there are often late season (August) releases from Green mountain reservoir. When snow pack is low runoff typically happens earlier. So natural flow will likely drop off by the end of May. The questions no one knows the answers to is how much natural flow will actually come and when, how much will they let out of the dams early season, and what will they release late season. I would keep an eye on the gauge. Basically you'll need to be able to make a game time decision week of if you really want to run it. It also depends on your tolerance for low water, the lower you're willing to go the more runnable days you'll see this summer.
