Location: Southeast Watershed Research2012 Annual Report
1a. Objectives (from AD-416):
Principal focus of the CEAP Watershed Studies is to evaluate the effects and benefits of conservation practices at the watershed scale, in support of policy decisions and program implementation.
1b. Approach (from AD-416):
The effects of conservation activities on water and soil quality will be assessed at the watershed scale using models such as ARS' Soil and Water Assessment Tool, in combination with ARS long-term watershed data sets, expertise, and resources.
3. Progress Report:
This project relates to Objective 2 of the in-house project above: Measure and quantify water quantity, water quality, and soil quality effects of conservation practices for sub-watersheds within the Little River Watershed. The CRIS project 6602-13000-025-00D was a bridging CRIS that was replaced by 6602-13000-026-00D in May 2012. 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.
