30 minute streamflow data measured and computed for the irregular weir located at the Marshall Gultch catchment outlet (Santa Catalina Mountains,Arizona). Streamflow are derived using pressure measurements to infer water levels and hence discharge in the weir. Pressure is measured using Onset Hobo pressure transducers model U20.

15 minute discharge data measured and computed for the Seep located at the Marshall Gultch schist catchment (Santa Catalina Mountains,Arizona). Discharge is measured by directing the flow from a spring into a large custom made tipping bucket measuring 1 liter per tip. Data is logged using an Onset hobo pendant event datalogger.
