45km buffer around the 'Far North PWA Zone A' (total of 50km from GAB springs.) Further detail provided in the Water Allocation Plan for the Far North Prescribed Wells Area section 2.1.3

100m buffer around the Far North PWA Refuge Non-Spring GDEs. Further detail provided in the Water Allocation Plan for the Far North Prescribed Wells Area section 2.2.3

Springs which are either fully or partially supported by water from the GAB aquifer and identified in the South Australian SA_Geodata Database GAB springs dataset. Further detail provided in the Water Allocation Plan for the Far North Prescribed Wells Area section 2.1.1

Either a well (unit number) that is identified on a water resource works approval issued for the Far North PWA, or a well which is known by the Department as part of a condition on an allocation as an existing operational production well. Data in this layer may require verification of the Department and should be considered accurate at a point in time only.

Non-spring GDEs identified to be at risk due to the taking of water and considered refuges within the landscape. Further detail provided in the Water Allocation Plan for the Far North Prescribed Wells Area section 2.2.1

See full Data Guide here. Aquifer Protection Areas Set is a 1:24,000-scale, polygon feature-based layer that includes all Preliminary (Level B) and Final (Level A) Aquifer Protection Areas approved by the Connecticut Department of Energy and Environmental Protection (DEEP). These areas represent the land area contributing ground water to active public water supply wells or well fields that serve more than 1000 people that are set in sand and gravel aquifers (stratified drift deposits). These areas are commonly referred to as wellhead protection areas. The Aquifer Protection Areas were delineated by the individual water utilities owning the well fields and submitted to the DEEP for approval. The preliminary mapping provides a general estimate of the area contributing ground water to the well field. The final mapping is based on extensive, site-specific, detailed modeling of the ground water flow system. As the final mapping is completed it replaces the preliminary mapping. The layer is based on information collected and compiled from 1991 to the present. The layer depicts current conditions. Attribute information is comprised of codes to uniquely identify individual features, encode the aquifer protection area type and status, and cartographically represent area features on a map. Data is compiled at 1:24,000 scale. This data is updated as final mapping becomes available.

Archived on 20161130 and the name was change from i08_B118_CA_GroundwaterBasins to i08_B118_CA_GWaterBasins20161130. The dataset is a feature class showing the boundaries of 515 groundwater basins and subbasins as defined by the California Department of Water Resources (Bulletin 118, 2003). The file is in ESRI geodatabase format and is intended for use with compatible GIS software. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards.
