WD-WaterUsers.mdb - Federal Water Contractors Mid-Pacific Region by Project, Division, Unit, Area Office, Settlement Contractors, Replacement Contractors, Repayment Contractors, Operational Agreement Contractors

Federal Water Contract boundaries are incorporated boundaries of districts having contracts with the U.S. Bureau of Reclamation (Reclamation). This database is designed as an ESRI geodatabase.  The feature classes in the database are districts that are assembled or grouped by Project, Division, Unit, Replacement Contractors, Repayment Contractors,  Districts within all area offices, Settlement Contractors, Operational Agreement Contractors.   Updates are determined by the needs of the local office and are composited from separate databases. Boundaries are updated as changes are identified by the Water Districts. The boundaries are not current for all Water Districts found in the database at the same time due to the update methods employed. There may be conflicts in the boundaries between districts due to the time of update, the review process associated, and issues between each Water District. Other problems may be associated with Water District name changes that may not have been updated by the Water District. 
The Klamath area water districts were digitized under a contract that the Klamath area office held with UC Davis in 1990.  MPGIS received those districts from the Klamath Area Office GIS center.
This database represents the most current and accurate understanding of the boundary location and current name of the Water Districts.

Calculation of acreage should be performed on the individual Water Districts.  Please ensure that the appropriate conversion value is used. This data is stored in meters.

The Federal Water Contract boundaries database is cooperatively shared between the U.S. Bureau of Reclamation (Reclamation), Mid-Pacific regional office (MP), MPGIS Service Center and the California Department of Water Resources (DWR). The Reclamation maintains this database with the voluntary assistance of the Federal Water Contractors. This database is used by Reclamation for various purposes including, but not limited to, contracting, operational, and maintenance purposes.

This database is not intended to be used as a land survey or representation of land for conveyance or tax purposes. The database is available to all users that may require this information.

No estimate of uncertainty in the placement of the polygon boundaries has been made. Source scale of separate boundaries varies between districts. Separate boundaries are compiled and registered to 1:24,000-scale USGS topographic maps.  No estimate can be made on the positional accuracy of the boundaries or on the currentness of the boundary position as depicted in the GIS databases.
