Mortality among 108 radio-tagged 2-year-old smolts of Atlantic salmon Salmo salar passed through a 17-MW Kaplan turbine was estimated at Holyoke Dam on the Connecticut River. The survival of test and control fish in 1981 was determined by comparing their rate of downstream movement with that of 28 prekilled fish. The survival of test fish in 1982 was determined as in 1981 by using nine prekilled fish. At full power generation, the mean percent turbine-induced mortality at 2 h (95% confidence interval in parentheses) was 11.8 (3.8–18.0) in 1981 and 13.7 (1.9–22.5) in 1982.
