SHP - Swift Hydroelectric Project

Fish enter the facility via a floating surface collector where they are sorted by size. Juvenile fish are either shunted directly to a holding tank to await transport downstream of Merwin Dam or they are sent to a sampling table where they are examined, possibly tagged, and sorted to either upstream of the Swift reservoir or downstream of Merwin Dam. All fish diverted to either tank pass through a PIT tag detector. There are two identical holding and sampling areas on the collector in which fish can travel. These areas are referred to the Port Side and Starboard Side. The port antenna was identified as 01 and the starboard antenna was 02. In February 2018 a third antenna was installed just above the sorting rack with an antenna ID of 01, and the port and starboard antennas were changed to 03 and 02, respectively.
