Smith-Root designed a barrier to prevent fish from moving upstream in a cooling water channel.
Forestburg, Alberta, Canada
This barrier prevents fish from traveling upstream into cooling water flows from a power station. The channel was narrowed from 137 to 49 feet wide at the barrier.
The Smith-Root design uses vertical steel pipe electrodes mounted on 30 HDPE piles, forming three array curtains with a relatively uniform field between them. Spacing across the stream is 8.2 feet, and up the stream is 9.8 feet. The array is just upstream from a small weir.
