The paired-basin approach was developed to evaluate impacts of forestry management on water quality, and has been adopted by researchers to evaluate management practices in agricultural land use settings. The methodology requires that two basins (control and treatment) are monitored for two time periods (calibration period and treatment period). If the two basins react in a consistent predictable manner while under similar management and climate during the calibration period, an alternate practice can be applied to one basin during the treatment period, and if the relationship between the basins changes, it is due to the treatment (Clausen 1993). The University of Wisconsin-Platteville’s Pioneer Farm has installed surface-water monitoring gauging stations in four agricultural basins and collected surface-water quality and quantity data for use in calibrating the basins for paired-basin research.
