About this source
Colorado Division of Water Resources via the CDSS HydroBase REST API (dwr.state.co.us). No auth. Active administrative calls show which water rights are curtailed by senior calls on a stream — directly relevant to industrial and frac-water sourcing in the DJ Basin. Also decreed water-right net amounts, groundwater well permits, and real-time telemetry stations, filterable by county, water division (1–7), and WDID.
