The 1995 evaluation was conducted to determine the proportion of radiotagged, hatchery-reared Atlantic salmon (Salmo salar) smolts passing through the log sluice at Cabot Station. Downstream passage facilities at Cabot consisted of reduced intake rack bar-spacing, spill through a 3.8 x 11 ft opening into the sluice, and above-water lighting at the sluice entrance. Atypical smolt behavior, interruption of illumination from overhead lighting, and escape of radiotagged smolts from the release facility (see Results) resulted in excluding four of the eight releases from analysis. The remaining four releases indicated that about 43 to 57% of radiotagged smolts passed downstream through the sluice with the sluice sampler not in place, but the data were insufficient to draw conclusions about the effectiveness of the passage facilities.
