Interactive Map

The NGPWC interactive map is a geographic information system (GIS) Web-based mapping program that allows the user to view water-related information within the NGPWC region. Spatially located features included in the interactive map include data related to traditional water resource information including streamflow gaging stations, groundwater systems, power plant locations, and related information and nontraditional water resource information related to municipal and industrial wastewater discharges.

The interactive map allows the user to easily navigate around the region, view data associated with the features, bookmark areas of interest, view the topographic profile of the landscape, and create and print personalized maps.

With the NGPWC interactive map, users will be able to quickly assess the potential availability of traditional or nontraditional water resources within their area of interest. The information available in the interactive map will allow the user to determine whether further investigation into the potential water availability is warranted for their desired use.
