The effectiveness of the BAFF system
was tested by randomly releasing approximately
1,000 acoustically tagged hatchery
smolts in batches over time about 15.5
miles upstream of the barrier, as part of
the CADWR Vernalis Active Management
Program. The travel of each tagged fish
was monitored by series of hydrophones,
located near the barrier. The travel path
of the smolts fitted with acoustic tags was
tracked as the barrier was turned alternately
on and off over time (Figure 7).

rence efficiency of the active BAFF barrier
was estimated at 81.4%. The BAFF was
put into operation in April 2009 during
the chinook salmon migration. In March
2011, CADWR deployed another, similar
328-yard-long BAFF system at the Georgiana
Slough in Walnut Grove, near Sacramento.
