Summary

This dataset shows land cover in the Upper Oconee watershed. The data layer primarily uses the 2011 National Land Cover Database (NLCD) but was manually edited to include 2,219 additional reservoirs. The reservoirs were identified and digitized using 2010 National Aerial Imagery Program (NAIP) imagery.

Purpose

Technological improvements in remote sensing and geographic information systems (GIS) have demonstrated the abundance of artificially constructed water bodies across the landscape. While research has shown the ubiquity of small ponds globally, and in the southeastern U.S. in particular, their cumulative impact in terms of evaporative alteration is less well quantified. These data were created as part of a study to examine the hydrologic and evaporative importance of small artificial water bodies in the Upper Oconee Watershed in the northern Georgia Piedmont, USA. Specifically, the USGS National Land Cover Database data for the study area were augmented with additional ponds that were visually interpreted from USDA National Aerial Imaging Program (NAIP) data. Comparative SWAT models were run with and without the inclusion of small reservoir surface area and volume data. That is, with these data as the treatment and standard NLCD data as the control.
