From email from Reclamation (Dan Crabtree):
Gunnison River flows in the Black Canyon and Gunnison Gorge are currently at 5,100 cfs and continuing to climb. We are still anticipating a peak flow of around 6,900 cfs in this reach tomorrow, June 7th or the following day. Flows at Delta are nearly 11,000 cfs and should peak at about 13,000 cfs late June 7th or early June 8th. We still anticipate slowly ramping down releases from the Aspinall Unit beginning June 9th and stabilizing at around 3,100 cfs in the Canyon and Gorge around June 14th.
