Stream Stage Data


Date/Time: Specifies the date and time the County Computer detected a transmission from the sensor.


Stage: Specifies the creek stage (in feet). The creek stage is the water surface level above a reference datum. It should be noted that the County's gauge stations' point of zero stage is several feet below the channel bottom. Therefore, the reported stage will often be greater than the actual water depth.


Discharge: Specifies the instantaneous stream flow rate at the gauge station in cubic feet per second (cfs).
