SWT - Sweetwater Cr. near its mouth

This is an in-stream interrogation system consisting of three separate antennas, 5 meters apart and approximately 0.1 kilometers upstream from the mouth of Sweetwater Creek. The upstream antenna B1, middle antenna B2, and downstream antenna B3 each consist of a single PVC encased flat-plate antenna. Antennas B1 and B3 are 15 feet wide and antenna B2 is 10 feet wide. The antennas all cover the width of the stream in all but the highest spring discharges (Figure 3). SWT is operated by the University of Idaho, Department of Fish and Wildlife Resources in coordination with Bureau of Reclamation. This new setup was installed in November 2011 and replaced the old setup that was originally installed in November 2010.
