About Twin Lakes
Twin Lakes is one of the 4 reservoirs BasinMind follows in the Arkansas basin, Division 2 of Colorado's seven water divisions. BasinMind's registry lists its operator as USBR (Fryingpan-Arkansas). Its recorded capacity is 140,900 acre-feet, the third-largest of the 4 and 14% of the capacity BasinMind tracks in the division.
On October 3, 2026 it held 99,736 acre-feet, 71% of that capacity, with room for about 41,164 acre-feet more. Over the seven days before, storage rose by 3,615 acre-feet. Taken together, the division's reservoirs with a current reading stood at 36% of capacity (353,492 of 974,018 acre-feet).
Daily storage comes from the Colorado Division of Water Resources, DWR station TWIRESCO; the official record is on that station's page. The nearest stream gauge BasinMind reads is Arkansas River at Granite, about 4 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).
