Aspinall Unit update: Reclamation’s winter target for Blue Mesa Reservoir — down to 7490 ft by December 31


From email from Reclamtion (Erik Knight):

Over the last couple months, releases at the Aspinall Unit have been lowered to accommodate maintenance activities at the powerplants at Blue Mesa and Morrow Point reservoirs, as well as for the brown trout spawn. These events have concluded and releases will now be increased to bring the elevation in Blue Mesa Reservoir down to the winter ice target elevation of 7490 ft by December 31st.

Releases from Crystal Dam will be increased by 200 cfs on Monday, November 21st. Another increase of 200 cfs is expected to be made the following Monday, November 28th. This will bring the total release up to 1000 cfs. Additional increases will be made in the first days of December to bring the total release from Crystal to 1550 cfs. Since there are no diversions to the Gunnison Tunnel at this time of year, flows in the Gunnison River through the Black Canyon will be in the 1500 to 1600 cfs range after the completion of these release changes.
