As part of the 2023 – 2028 Water Supply Plan update, DWSG developed an ArcGIS Online product called “New Jersey Water Withdrawal Data Summary Viewer”. The interactive map allows users to select, plot and download water withdrawal data by either municipality or 14-digit hydrologic unit. It provides an alternative way of viewing withdrawal data that is also included in the DGS13-1 file. Data can be viewed statewide or by selecting one or more of the geographic divisions. Downloads, in CSV format, are reflective of municipality or HUC14 selection. Data can also be sorted by source of water (e.g. groundwater, surface water, etc.) or by use of water (e.g. potable, agriculture, power generation, etc.). The dashboard can be viewed at New Jersey Water Withdrawal Data Summary Viewer. This new graphical and interactive format should increase user access and accessibility.[/vc_column_text][/vc_tta_section][vc_tta_section i_type=”typicons” i_icon_typicons=”typcn typcn-map” add_icon=”true” title=”Geologic Maps” tab_id=”1712598073739-eaca6a0e-d3d5″][vc_column_text css=””]OFM 171 Geologic Map of the Egg Harbor City Quadrangle, Atlantic and Burlington Counties, New Jersey.

Latest Drought News Releases:
New Jersey is under a Statewide Drought Warning due to persistent below-average precipitation and deteriorating water supply conditions. Under the authority granted by an Administrative Order, Department of Environmental Protection (DEP) is working closely with water suppliers to monitor conditions and implement measures that preserve and balance available water resources. This includes coordinated actions such as water transfers, controlled reservoir releases, and adjustments to stream flow rates to protect both ecological health and water supply needs. All residents and businesses are urged to conserve water and use it wisely to help prevent more severe shortages.
