Interpretive Summary: To provide support for the Conservation Effects Assessment Project (CEAP), the Agricultural Research Service (ARS) is implementing a web-based data system - STEWARDS (Sustaining the Earth's Watersheds - Agricultural Research Data System). STEWARDS consists of three components: "Local Sites" which supply data from each of the ARS Watershed Assessment Study sites; "Client Sites" which represent data users; and a central database management system. The climate, water, soil, land-management, and economic data will be supplied and annually updated into STEWARDS from the twelve ARS Watershed Assessment Study sites. STEWARDS will provide tools to allow users to view and download the data. A prototype (ancestor) of STEWARDS has been developed at the Grazinglands Research Laboratory, El Reno, Oklahoma, using data from the Fort Cobb Reservoir Experimental Watershed (FCREW) and Little Washita River Experimental Watershed (LWREW). We present an example illustrating the data system features which allow users to visualize and explore data. Another example is given which illustrates how the Soil Water Assessment Tool (SWAT) modeling is supported and enhanced by the STEWARDS.

Technical Abstract: To provide support for the Conservation Effects Assessment Project (CEAP), the Agricultural Research Service (ARS) is implementing a web-based data system - STEWARDS (Sustaining the Earth's Watersheds - Agricultural Research Data System). STEWARDS consists of three components: "Local Sites" which supply data from each of the ARS Watershed Assessment Study sites; "Client Sites" which represent data users; and a central database management system. The climate, water, soil, land-management, and economic data will be compiled and annually updated into STEWARDS from the twelve ARS Watershed Assessment Study sites. The visualization and tabular interface tools allow the users to view and download the data. A web-based prototype data system has been developed at the Grazinglands Research Laboratory, El Reno, Oklahoma, using data from the Fort Cobb Reservoir Experimental Watershed (FCREW) and Little Washita River Experimental Watershed (LWREW). We present an example illustrating the data system features which allow users to visualize and explore data (water quality, discharge, and precipitation). Another example is given which illustrates generation of input files for the Soil Water Assessment Tool (SWAT) and how SWAT modeling is supported and enhanced by the STEWARDS.
