These data readings are Preliminary. Most data relayed by telemetry have received little or no review. Inaccuracies in the data may be present because of instrument malfunctions and/or physical changes at the measurement site. Subsequent review may result in significant revisions to the data. GOES Satellite Transmissions (denoted by :00, :15, :30, :45 min. time values) occur every 15 minutes. Single 15 minute values transmissions may occur during storm events. **October 21, 2022 Update-Valley Water has completed converting Streamflow and Reservoir Gages from hourly to more frequent 15 min. data transmissions.**
