Abstract: The HI-Z Turb'N Tag was used to assess injury and mortality incurred by Atlantic Salmon (Salmo salar) smolts bypassed through ice-log sluiceways at two stations. Both sluiceways were similar in height (52 and 60 ft) and spillage (approximately 300 cfs). Total survival 48 h after passage was at least 96 % at both facilities. However injury and scale loss were markedly different at the two facilities (42 vs 3%). The facility with a deep, unobstructed plunge area and minimal intercepting structures inflicted least injuries.
