In 2007, the U.S. Bureau of Reclamation (USBR) constructed a scale model test at its Hydraulic Laboratory in Colorado, where the effectiveness of the BAFF using SPA, highintensity light bars, and an air bubble curtain was tested (Figure 4). The data collected from the USBR flume testing was used to design a full-scale 112m barrier that was later installed by the California Department of Water Resources (CADWR) at the Head of Old River, located in Lathrop, Calif. (Figure 5).
