General Replacement Reservoir to a Diversion by a Direct Release or Exchange (ityopr=10)

The type 10 operating rule provides a method to supply reservoir water to a large number of structures without supplying individual operating rules for each. The following are noted:

  • The operating rule checks whether reservoir replacement water will be supplied to a diversion by a direct reservoir release or exchange.
  • The operating rule serves all water rights which are senior to its Administration number which have variable ireptyp of the Direct Diversion Station File (*.dds) set to 1 or -1.
  • The variable ireptyp specified by structure in the diversion station (*.dds) file specifies if replacement releases are to be made for the full diversion (ireptyp = 1) or depletion (ireptyp = -1) or not at all (ireptyp = 0).
  • When more than one replacement reservoir is specified, they are sorted by Administration number and operate by priority, most senior first.
  • The replacement reservoir operating rule applies to direct flow structures only, therefore carrier systems must be tied to a replacement reservoir directly. The following are noted:
    • The replacement reservoir operating rule has generic applications but was originally developed to handle the replacement reservoir obligations of Green Mountain Reservoir in the Colorado River Basin.
    • When a replacement reservoir operating rule is included in a simulation and the release from a replacement reservoir is non-zero, additional information associated with the replacement reservoir operation is provided in the replacement reservoir summary (*.xrp).
