Recent Work in Fish Passage
Many utilities in the U.S. are performing work on fsh passage.
Tis article elaborates on some of the work being performed, lessons
learned to date and future research directions.

Moving fsh past dams, particularly those that impound water for hydroelectric powerhouses, is vital
to maintaining ecosystem health and adequate
fsh populations. Much work has gone into
ensuring adequate, efective fsh passage, both
in terms of research and actual implementation
of fsh passage at dams.
Tis article provides information on recent
work with regard to fsh passage from several
Reclamation’s fsh passage work
Te U.S. Department of Interior’s Bureau of
Reclamation recently announced four fsh
passage research awards, aimed at identifying potential solutions to move juvenile fsh
downstream past tall dams. Fish migration
is needed to ensure habitat connectivity for
threatened and endangered fsh populations,
Te awards were given as part of a prize
competition. Reclamation collaborated
with U.S. Geological Survey, NOAA –
National Marine Fisheries Service, the U.S.
Fish and Wildlife Service and U.S. Army
Corps of Engineers to design and judge
Te federal government receives a perpetual, no-cost right to use any of the ideas
submitted, and Reclamation is developing a
plan to further test, develop and demonstrate
the efectiveness of the ideas submitted. Te
top winner, who received $10,000, involved
The Bonneville Dam and 1,242-MW hydro plant is just one location where
the U.S. Army Corps of Engineers is conducting fish passage research.
