On October 3, 2026 it held 120,930 acre-feet, 98% of that capacity, with room for about 2,611 acre-feet more. Over the seven days before, storage rose by 291 acre-feet. Taken together, the division's reservoirs with a current reading stood at 51% of capacity (1,210,613 of 2,393,162 acre-feet).
Daily storage comes from the Colorado Division of Water Resources, DWR station BASRESCO; the official record is on that station's page. The nearest stream gauge BasinMind reads is Animas River below Durango Pump Plant near Durango, about 3 miles away in a straight line.
