*The water year is named for the calendar year in which it ends. Example: the 2014 water year begins Oct. 1, 2013 and ends Sep. 30, 2014.

Method(s) of Measurement:
WOFWeir or Flume measurement of flow rate x time
ECFEstimate cfs allowed by water right x 1.98 x days used per month = AF
OTHcfs=HPx8.8xefficiency/H in ft where H in ft=outlet psi/0.434+depth of static H2O where hrs=kwh/1.34x (1996)
OTHNone (2019)
OTHPump Formula (2018)

  • Monthly amounts indicate:
    • For diverted rights, the total amount diverted during the month;
    • For storage rights, the amount generally stored in the reservoir/pond during the month, as represented by the volume of water impounded on approximately the same day each month.
  • Water Use amounts have all been converted to "acre-feet" (AF), regardless of the original measurement unit reported. One AF is the volume of water that will cover an acre of ground one foot deep = 325,850 gallons.
  • Zeroes indicate that a report was received, stating that no water was used during those months; if a year is not listed, no report of water use was received for that year.
