Khris is exactly right. The water coming from Dillon that is "owed-to-Green Mountain" will be stored in Green Mountain until we release it to our downstream customers.
For this weekend, I'm guessing Lower Blue flows will range from the upper 400s to the lower 600s in cfs. Currently, we're around 510 cfs, I think, or we will be later today after they make the latest change.
