Evaluation of a free-fall apparatus for downstream passage of Atlantic salmon (Salmo salar L.) / R.K. Sweeney and R.J. Rutherford.: Fs97-4/1632E-PDF
"The design of economical, downstream-passage facilities for Atlantic salmon (Salmo salar) kelts and smolts at hydroelectric dams often includes a free fall to the tailrace. To determine the height of fall which could be tolerated by this species without immediate mortality, kelts and smolts were dropped from a plywood flume with a water discharge of 0.42 M3 /sec. The smolts were dropped a vertical distance of 18.0 m, while the kelts, both grilse and older salmon, were dropped from both 10.6 m and 18.0 m. Survival was dependent upon impact velocity, with fatal injuries occurring above 15.2 m/sec. The experimental results indicate that this velocity would be reached when smolts fell 21 m, grilse kelts 18 m and salmon kelts 16 m"--Abstract, page vii.
