From email from Reclamation (Dan Crabtree):
The Uncompahgre Valley Water Users will be increasing diversions through the Gunnison Tunnel this afternoon, bringing Tunnel diversions up to about 750 cfs. This will result in Black Canyon and Gunnison Gorge flows of about 1,250 cfs.
Please note, Reclamation will be holding the April Aspinall Operations meeting on April 21st starting at 1:00 p.m. in the Grand Junction Western Colorado Area Office located at 2764 Compass Drive Suite 106. We will be discussing past operations and the upcoming spring runoff operations. Everyone is welcome to attend.
