2012 Annual Report
The Southeast Watershed Research Lab (SEWRL) in Tifton, Georgia continued its effort to characterize the hydrologic and water quality conditions of the Little River Experimental Watershed (LREW). These data are critical to our efforts to relate conservation practices, land use, and agricultural management throughout the Watershed to the observed water quantity and quality within it. Support from the Agricultural Research Service Conservation Effects Assessment Program (CEAP) was used to sustain and further enhance our streamflow, climate, and water quality programs within the watershed. Additional CEAP support was used to maintain and enhance the LREW automated data collection system (http: //www.tifton.uga.edu/sewrl/radio/lrdata.htm) which provides near real time climatic and hydrologic data for the Upper Suwannee River Basin. LREW data through 2009 were made available within the Sustaining the Earth's Watersheds, Agricultural Research Data System (STEWARDS) as well as the SEWRL web site. The impacts of conservation tillage systems and riparian buffers across the watershed were assessed using the models and comparisons made to the LREW observed hydrologic and water quality data. ARS scientists participated in the annual CEAP meeting in conjunction with the Soil and Water Conservation Society Annual meeting in Fort Worth, Texas and reported on CEAP activities in ARS related to pesticides and modeling.
