Aspinall Unit update: 600 cfs in the Black Canyon next week — target level for the brown trout spawn


From email from Reclamation (Erik Knight):

As per normal fall reservoir operations, releases from the Aspinall Unit will be decreased over the next few weeks in response to the seasonal shutdown of the Gunnison Tunnel and the brown trout spawn. Gunnison Tunnel diversions were decreased by 100 cfs yesterday so releases from Crystal will follow this and make an additional 100 cfs reduction today, October 11th. This total reduction of 200 cfs will bring Crystal releases down to 1600 cfs and flows in the Gunnison River through the Black Canyon down to 850 cfs by the end of today. This year’s river target level for the brown trout spawn will be 600 cfs which will be reached sometime within the next week.
