Abstract: This data delineates New Jersey drought regions, counties, and municipalities. Drought regions provide a regulatory basis for coordinating local responses to regional water-supply shortages. The six drought regions are based on watershed and water-supply considerations. Drought region boundaries coincide with municipal boundaries as referenced by the N.J. Dept of Environmental Protection (NJDEP). Each municipality in New Jersey is assigned to a drought region based on the watershed covering and supplying water to the municipality. Each data record of the file includes name and numeric code entries for counties and municipalities, and names of drought regions. This is the second version of the drought regions. It differs from the original delineation in two ways: 1) The number of drought regions were expanded from five to six in order to account for water-supply issues identified for the New Jersey coastal plain. The original version included the north part of the Coastal Plain in the central region. Version 2 separates a north coastal region, consisting of Monmouth and northern Ocean Counties, from the coastal region to the south. 2) Municipalities in Mercer County receiving water from the Trenton Water Dept. were moved into the southwest region from the northwest. Pennington and Hopewell boroughs were also moved to the southwest region. Please reference this data as follows: Hoffman, J.L, 2000, Drought regions in New Jersey: N.J. Geological Survey Digital Geodata Series DGS 00-1, Trenton. It is available for downloading from the N.J. Geological Survey's web page at http://www.state.nj.us/dep/njgs
Purpose: The drought regions are designed to assist the DEP in declaring drought warnings and emergencies in New Jersey during times of decreased precipitation, and current or anticipated water-supply shortages. By having different regions it is possible for the State to declare drought warnings or emergencies in different regions. These warnings and emergencies are declared by the Governor of the State of New Jersey. The State's response to a drought is coordinated by the NJDEP Water Supply Element.
Supplemental Information: drghtregmun is an ArcView shapefile. A shapefile is composed of three separate files having the extensions.shp, .shx, and .dbf. The *.shp file contains the spatial information, the *.shx file is an index file,and the *.dbf file contains the polygon attribute information. This product includes the files drghtregmun.shp, drghtregmun.shx, drghtregmun.dbf. It consists of vector data with arc-node topology. Spatial objects include polygons with x,y coordinates. There are 582 polygons. Note: Attribute information (except for Drtreg) can be found in the State Municipalities metadata at: http://www.state.nj.us/dep/gis/digidownload/metadata/statewide/stmun.htm
