From email from Reclamation (Erik Knight):
The Uncompahgre Valley Water Users Association (UVWUA) will be diverting an additional 100 cfs through the Gunnison Tunnel Monday morning, April 14th. At the same time, releases from Crystal Dam will also be increased by 100 cfs, from 850 cfs to 950 cfs. After this change, the total flow through the Gunnison Tunnel should be about 500 cfs, which should leave about 450 to 500 cfs in the Gunnison River downstream of the tunnel.
