Recharge Well (ityopr=44)

The type 44 operating rule provides a method to pump a Recharge well in order to fill a Recharge Reservoir. The following comments are provided to assist in using and interpreting this rule:

  • A recharge well operating rule ties a well right (ciopso(1)) to a recharge reservoir (ciopdes(1)) and account (iopdes(2,1)). Typically the recharge reservoir’s seepage provides a lagged water supply for an augmentation plan.
  • A recharge well only diverts when it is in priority.
  • A recharge well is typically located close to the river and has a relatively quick, if not instantaneous, impact on the river. This quick response is not a requirement, simply how they typically operate. If the recharge well has a lagged depletion that is out of priority its augmentation requirement is included in the plan data (creuse). The depletions associated with this source are specified in the well station file (*.wes).
  • A recharge well might serve as both a water supply and a recharge reservoir’s source. This can occur when the same well right is assigned to both a standard (irrigation) well structure and a type 44 operating rule. If the administration number assigned in the operational right file is different than the administration number of the source (augmentation) well the operating rule value is used and a warning is printed to the log file. The amount pumped to each demand is limited by the well’s total capacity and water right.
