This dataset is part of the Cadastral National Spatial Data Infrastructure (CadNSDI) publication dataset for rectangular and non‐rectangular Public Land Survey System (PLSS) data.

This dataset represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully Intersected (all of the PLSS feature at the atomic or smallest polygon level), PLSS Townships, First Divisions and Second Divisions (the hierarchical break down of the PLSS Rectangular surveys) PLSS Special surveys (non-rectangular components of the PLSS) Meandered Water, Corners and Conflicted Areas (known areas of gaps or overlaps between Townships or state boundaries). The Entity-‐ Attribute section of this metadata describes these components in greater detail.

The CadNSDI or the Cadastral Publication Data Standard is the cadastral data component of the NSDI. This is the publication guideline for cadastral data that is intended to provide a common format and structure and content for cadastral information that can be made available across jurisdictional boundaries, providing a consistent and uniform cadastral data to meet business need that includes connections to the source information from the data stewards. The data stewards determine which data are published and should be contacted for any questions on data content or for additional information. The cadastral publication data is data provided by cadastral data producers in a standard form on a regular basis.

Cadastral publication data has two primary components, land parcel data and cadastral reference data. It is important to recognize that the publication data are not the same as the operation and maintenance or production data. The production data is structured to optimize maintenance processes, is integrated with internal agency operations and contains much more detail than the publication data. The publication data is a subset of the more complete production data and is reformatted to meet a national standard so data can be integrated across jurisdictional boundaries and be presented in a consistent and standard form nationally.

Program Background - ADWR has two key groundwater well data sets for the state of Arizona. The 'Wells 55 Registry' corresponds with this WellRegistry GIS layer and contains all wells registered in the state. The database was originally created in 1980 to store registration information submitted by well owners and drillers. It contains over 200,000 well records. A second key well data set is also maintained at ADWR. The Groundwater Well Site Inventory (GWSI), is a statewide database that contains well locations, construction, and water level measurements for wells that have actually been located and sampled in the field (originally by the USGS and since 1990 by ADWR). The GWSI database contains over 45,000 well records. Of those, approximately 24,700 have been ‘matched’ to the Wells 55 Registry and therefore have a 'Wells 55 Registry ID'.Purpose and intended use - This data is used by both internal and external customers and is most commonly used to search for registered wells within the State.Data creation methodologies, processing, and quality - The database was originally created in 1980 to store registration information submitted by well owners and drillers. New wells are added as driller logs and reports are received.Data limitations – Please refer to ADWR Data Disclaimer. This data set contains data submitted by well owners and well drillers. Data availability is therefore limited to data provided by the public. The wells mapped to the centroid of the containing Cadastral (normally Quarter-Quarter-Quarter Section). More precise user-submitted locations are not contained in this GIS layer, however they are stored internally and are available to the public upon request for approximately 20% of the wells.Currency – Updated dailyContact – Manager, Groundwater Permitting and Wells, (602)771-8527Use limitations – Please refer to ADWR Data Disclaimer.Attribute information - programADWR program codeREGISTRY_IDUnique identifier for well record in the Wells 55 Registry database.owner_nameThe registered owner of the wellrgr_pump_dataWas water removed before 2008 or was water received in the last yearwelltypeType of wellwell_type_groupWell Type groupdlic_numMost recent driller's license numberapprovedThe earliest date in which drilling was approvedinstalledThe earliest date of well constructionwell_depthThe depth of the well in feetwater_levelThe reported depth to water in feetcasing_depthThe depth of the well's casing in feetcasing_diameterThe diameter of the well's casing in inchescasing_typeThe type of casing usedpump_typeThe type of pump usedpump_powerThe method of how the pump is poweredpumprateThe rated pumping capacity in gallons per minutetestedrateThe tested pumping capacity in gallons per minutedraw_downThe amount of water that pumping has lowered the water level in feetcompletion_report_statusStatus for reporting the completion level of the well (X-Completed, I-Incomplete, A-Abandoned, N-no report required)drill_logThe driller log's received status (X-Completed, I-Incomplete, A-Abandoned, N-no report required)well_cancelledThis indicates if the well was cancelledCadastralCadastral code indicating township, range, section location information.
