StateDMI / Command / SetWellSystem

Overview

The SetWellSystem command (for StateCU and StateMod) sets well system part identifier data for:

  • a CU Location that corresponds to a location with well supply
  • or StateMod well station

Well systems are specified using a list of part identifiers as follows:

  • Part type is Ditch
    • The collection includes wells that are associated with a list of ditches, identified using ditch water district identifiers (WDIDs). The list of ditches is used for the full period.
  • Part type is Parcel
    • The collection includes wells that are associated with a list of parcels.
    • The division and year must be specified in the command because well to parcel relationships are determined for specific years. This approach was used in the past for all basins but is being phased out and is currently only used for Rio Grande. It may also be phased out for the Rio Grande.
  • Part type is Well
    • The collection includes wells identified by well WDID or well permit “receipt”.
    • Receipts should be specified with a leading P: (e.g., P:1234567A) in which case the leading P: will be stripped and the remainder used for the receipt during processing.
    • The internal part ID type will be set to WDID or Receipt, as appropriate. This approach is being phased in and is preferred.

To facilitate processing, it is often best to use list files to specific aggregates (see the SetWellSystemFromList command). Systems by convention have their water rights fully represented in output. To aggregate water rights at a location, use an aggregate (see the similar SetWellAggregate and SetWellAggregateFromList commands). See also the StateDMI Introduction chapter, which provides additional information about aggregates and other modeling conventions. System information should be specified after well locations are defined and before their use in other processing, such as reading data from HydroBase.

Well parcel data are queried in bulk when first requested and are cached to speed later processing. One level of caching is water district, which is available for all wells. The water district can be determined from a WDID but well receipts require querying to match the receipt and then use the matching WD. This step is performed when a system is defined so that later data access can use the WD.

Command Parameters

Parameter             Description Default          
ID
required		 The well identifier to associate with the collection of individual wells. None – must be specified.
PartType
required		 Indicate the type of features being aggregated and specified by PartIDs, one of:
  • Ditch – the PartIDs (ditch WDIDs) indicate ditch service areas supplemented by wells.
  • Parcel – the PartIDs (parcel numbers from GIS processing) indicate parcels irrigated by wells, with no surface water supply.
  • Well – the PartIDs indicate wells (WDIDs or permit receipts), with no surface water supply. Include P: at the start of receipt identifiers.
 None – must be specified.
Year The year defining the parcels. Required when PartType is Parcel because parcel identifiers from well matching are specific to the data year.
Div Water division for the parcels in the system. Required when PartType is Parcel because parcels require the division.
PartIDs The list of part identifiers to comprise the system. None – must be specified.
IfNotFound Used for error handling, one of the following:
  • Fail – generate a failure message if the identifier is not matched
  • Ignore – ignore (don’t add and don’t generate a message) if the identifier is not matched
  • Warn – generate a warning message if the identifier is not matched
 Warn
