About Blue Mesa Reservoir
Blue Mesa Reservoir is one of the 7 reservoirs BasinMind follows in the Gunnison basin, Division 4 of Colorado's seven water divisions. BasinMind's registry lists its operator as USBR (Aspinall Unit). Its recorded capacity is 940,700 acre-feet, the largest of the 7 and 72% of the capacity BasinMind tracks in the division.
On October 3, 2026 it held 145,201 acre-feet, 15% of that capacity, with room for about 795,499 acre-feet more. Over the seven days before, storage rose by 448 acre-feet. Taken together, the division's reservoirs with a current reading stood at 30% of capacity (385,570 of 1,307,616 acre-feet).
Daily storage comes from the Colorado Division of Water Resources, DWR station BLMRESCO; the official record is on that station's page. The nearest stream gauge BasinMind reads is Cimarron River below Cimarron Creek at Cimarron, about 12 miles away in a straight line.
An acre-foot is the water that would cover one acre a foot deep, about 325,851 gallons; percent full compares storage with recorded capacity, not with what is normal for the date (cfs and acre-feet).
