The Little River Experimental Watershed is located in the headwaters of the Upper Suwannee River basin and is one of twelve national benchmark watersheds participating in the U.S. Department of Agriculture Conservation Effects Assessment Project–Watershed Assessment Studies. A geographic database has been established to include topography, land use, hydrology, soil distribution, watershed boundaries, and site locations for all weirs, rain gauges, soil moisture sites, and climate stations. These data provide the foundation for integrating point‐based measurements with landscape attributes. Each spatial layer can be accessed individually for use within a geographic information system. The watershed boundary layer will serve as the base map, projected into universal transverse Mercator coordinates (zone 17), using NAD83 as the datum and GRS80 as the ellipsoid.

The Little River Experimental Watershed located in the headwaters of the Upper Suwannee River basin is one of twelve national benchmark watersheds participating in the U.S. Department of Agriculture (USDA) Conservation Effects Assessment Project–Watershed Assessment Studies (CEAP‐WAS). Historical paper files and maps (circa 1980–2006) were collected and used to develop a geographic database of conservation practices supported by the USDA Natural Resource Conservation Service. The CEAP‐WAS database can be queried by conservation practice, total acreages enrolled, year of implementation, and location. The CEAP‐WAS database is integral to understanding the links between conservation practice implementation and placement with observed changes in hydrologic processes within a small southern Coastal Plain watershed. All associated geographic information has been provided in shapefile format and has been projected into universal transverse Mercator coordinates (zone 17), using NAD83 as the datum and GRS80 as the ellipsoid. Data may be accessed via ftp://www.tiftonars.org/, archived in a folder named ceap_data.

ABSTRACT. The Better Assessment Science Integrating point and Nonpoint Sources (BASINS) system was developed by the U.S. Environmental Protection Agency to facilitate developing total maximum daily loads (TMDLsater is our most valuable resource. Realizing its value, states and nations often argue over water rights and protection. An increasing awareness of the value of water has resulted in considerable improvement in water conservation and preservation. Over the past 20 years, substantial reductions have been achieved in the discharge of pollutants into the lakes, rivers, wetlands, estuaries, coastal waters, and groundwater. Despite significant progress in reducing pollution, over 40% of the assessed waters in the U.S. still do not meet set standards (www.epa.gov/owow/tmdl/). These waters amount to over 20,000 individual river segments, lakes, and estuaries, including nearly 500,000 km of rivers and shorelines and approximately 2 million ha of lakes.
