2011 3/16/2011 12:00 AM 1/1/2012 12:00 AM First year of operation since 1992. The current configuration consists of the three fishway antennas previvously reported as RZF, and two new five-ft flat-plate antennas deployed in parallel on the West spillway roller gate. In 2011, spill at the West roller gate is normally confined to the 10-ft section over the flat-plates. Water flowed across the full 100-ft width of the West roller gate from March 30 - April 12.
