- wtallis 10y agoThe outflow seems to be the ~100000 cfs from the main spillway draining at full capacity, which they opened to 100% early in the evening to relieve the emergency spillway, in spite of the existing damage to the main spillway.
- jnsaff2 10y agoThank you. By the way there's an amazing book that has a very gripping account of the Glen Canyon Dam incident and Grand Canyon in general. http://www.goodreads.com/book/show/15803144-the-emerald-mile http://www.goodreads.com/book/show/15803144-the-emerald-mile

- Animats 10y agoIt's good to see the lake level coming down. 896 feet now, four feet below overflow at the emergency spillway. Don't take the outflow rate number too seriously. The emergency spillway is just a concrete lip with no flow metering.
