None supplied. From executive summary: A study conducted in 1987 at Bellows Falls Station showed that under certain conditions, up to 37 percent of downstream migrating smolts passed downstream of the powerhouse via the log and ice sluiceway, thereby avoiding turbine passage. The present study was conducted primarily to evaluate whether lighting modifications to the log and ice boom and sluiceway entrance would promote smolt utilization of the sluiceway for downstream passage. Other study components included a preliminary assessment of smolt migration and behavior at Vernon Dam (located 35 miles downstream), and an assessment of the practicability of sluiceway netting of smolts at Bellows Falls Station. This study indicated that the lighting modifications did not substantially improve smolt utilization of the sluiceway for bypassing the turbines.
