The watershed layer was created as part of the New Jersey Pinelands Commission ecological-integrity assessment (Zampella et al. 2008). Watersheds were created using NJDEP (1996) stream data, a digital-elevation model (NJDEP 2002), and Arc Hydro (ESRI 2007). This shapefile contains the watersheds for the Pinelands Area. ESRI. 2007.

The watershed layer was used in conjunction with the drainage-unit layer to determine the aquatic integrity of Pinelands drainage units.

Watersheds were created using NJDEP (1996) stream data, a digital-elevation model (NJDEP 2002), and the Batch Watershed tool in Arc Hydro (ESRI 2007). Arc Hydro is a water resources tool designed to work within ArcGIS (ESRI 1999-2006). Points, referred to as pour points, were placed immediately above the confluence of streams or stream segments and the DEM was used to delineate the total area contributing stream flow to each pour point. To reduce variations in scale, streams or segments of streams that were two or more times as long as the median length of all first-order Pinelands streams were divided until they were less than twice the length of the median value. The total upstream area draining to a pour point represents the watershed. ESRI. 1999-2006. ArcGIS 9.2. Environmental Systems Research Institute, Redlands, California, USA. ESRI. 2007.
