About the San Juan/Dolores basin
The San Juan/Dolores basin is Division 7 of Colorado's seven water divisions. It takes in the San Juan River basin and part of the Dolores, and its Division Engineer's office and water court sit in Durango. BasinMind follows conditions here at Durango, Cortez and Pagosa Springs.
The division is split into 11 water districts, the units water commissioners administer day to day. The first two digits of a structure's WDID are its district (What is a WDID?).

BasinMind follows 6 reservoirs in the division, with the capacity it records for each: Navajo Reservoir (1,708,600 acre-feet), McPhee Reservoir (381,195 acre-feet), Vallecito Reservoir (129,700 acre-feet), Lake Nighthorse (123,541 acre-feet), Lemon Reservoir (40,146 acre-feet) and Jackson Gulch Reservoir (9,980 acre-feet). The largest is Navajo Reservoir; daily storage comes from Colorado DWR telemetry or Reclamation.
Its rivers belong to the Colorado River system, shared by seven states under the Colorado River Compact (1922), and the La Plata River Compact (1922) with New Mexico governs the La Plata. More in The Colorado River Compact.
Water planning here runs through the Southwest Basin Roundtable of the Colorado Water Conservation Board.
Each figure above carries the time its source stamped it. Percent of median compares today's flow with the median for this date over the gauge's record (cfs and acre-feet); a call shows how far down the priority list rights are being served on a stretch of river (What is a water call?).
