adminNumber

A calculated number developed by DWR to rank water rights in order of seniority. The priority of the water right is based on the appropriation date and whether the water right is subject to the Subordination Doctrine. The appropriation date is the date decreed by the court that the water was first put to the decreed beneficial use. The Subordination Doctrine established by the court says water rights that are adjudicated after other water rights in their stream system must be subordinate to those rights previously decreed, regardless of their appropriation date. To determine whether or not a water right is subject to the Subordination Doctrine, DWR determines the "previous adjudication date" associated with the water right. Water rights that have no previous adjudication date or have an appropriation date that is later than the previous adjudication date can simply use their appropriation date as their administrative priority. Water rights with an appropriation date the same as or earlier than the previous adjudication date must be subordinated to those previously decreed rights. Using the appropriation date and previous adjudication date, the Priority Admin No (PAN) is calculated as follows:

  • If a water right has no previous adjudication date or the appropriation date of the water right is later than the previous adjudication date: the left side of the PAN is the number of days between 12/31/1849 and the appropriation date; and, the right side of the PAN is zeros (.00000).
  • If the appropriation date of a water right is the same as or earlier than the previous adjudication date: the left side of the PAN is the number of days between 12/31/1849 and the previous adjudication date; and, the right side is the number of days between 12/31/1849 and the appropriation date.
