San Juan River at Mexican Hat

    Welcome
Welcome to SanJuanFlows.info. This site is designed as a one stop source for viewing San Juan River flow and diversion data between Navajo Reservoir, NM and Mexican Hat, UT. All real-time and historic river flow data come from the USGS web site.  All reservoir data comes from the USBR.  This data is retrieved daily and stored in our online database.  All data on this site should be considered provisional unless otherwise noted.

During the irrigation season, all real-time diversion data are uploaded via satellite every hour and made available to this site by the USGS. We automatically retrieve the data every hour. Equipment used in collection and telemetry of diversion data are maintained by various entities not associated with the USGS.

Information on Site Use
