From email from Reclamation (Andrew Limbach):
The Aspinall Unit spring peak operation has been scheduled for Wednesday, May 27th. The schedule for the ramped increase and decrease in releases is as follows:
The purpose of this release is to satisfy the Black Canyon Decree spring release. Due to the maintenance outage ending on May 20th and unseasonably early peak runoff of the North Fork, this spring peak release timing was chosen to coincide with equal or greater inflows to Blue Mesa Reservoir.
