Partnering with the Brazos River Authority (BRA) initially consisted of an assessment of the Bosque River Watershed (a drainage area comprising a tributary of the Brazos), which terminates with Lake Waco. The watershed area covers 4,300 sq. km (1,650 sq. mile) in portions of six counties. Major issues investigated were sediment and nutrient sources and relative contributions of these constituents into Lake Waco. The upper reaches of the watershed have a heavy concentration of confined animal feeding operations (CAFOs). Nutrients also originate with the fertilization of cropland concentrated in the lower portion of the watershed and point sources such as wastewater treatment plants.
