San Juan Flows - Reservoirs, River Flows, and Diversions

Reservoir data comes from the USBR. This data is retrieved daily and stored in the San Juan Flows database. All data on this site should be considered provisional unless otherwise noted. During the irrigation season, real-time diversion data for the Hogback and Fruitland diversions are uploaded via satellite every hour and made available to us by by the USGS. We automatically retrieve the data every hour. Equipment used in collection and telemetry of diversion data are maintained by the Navajo Nation.
