| Watershed Description: | 4,277 km^2 Bosque River, located in north central Texas, U.S. |

| General Comments: | Study focused on in-depth calibration and validation of SWAT at two sites in the watershed. The resulting r2 and E values indicated that SWAT performed well for both flow and pollutant estimates. A detailed table of calibration parameters is also presented, and extensive graphical results are shown. |
