- Discharge is the measure of water flow. Surface water station are measured in cubic feet per second (cfs), and ground water stations are measured in gallons per minute (gpm).
- Gage Height is the measure of water level. Surface water stations are measured in feet (ft), and ground water stations are measured in feet below ground surface (ft bgs).
- Daily Average Flow Rate is the average of the flow values, in either cfs or gpm, for that day (from 00:00 to 23:59 hours). So as the flow values are updated with the newest timestamp value, the reported average will be updated based on the most current flow value.
- Daily Total Volume is the total volume, in acre-feet, for that day (from 00:00 to 23:59 hours). So as the flow values are updated with the newest timestamp value, the reported total will be updated based on the most current flow value.
- NR (Not Reported) indicates the value is not presently reported. Contact the appropriate district office for further information.
