Bailey Construction have completed the first of the Larinier fish passes which is located at Steelbank weir.

The baffles on the inside of the pass are what makes this a ‘Larinier’ pass, named after the man who invented them.  The baffles disrupt the flow of water, making it easier for the fish to ascend the pass.  There is a  resting pool in between the two flights which is to allow the fish to rest before attempting to ascend the second flight.

They have also completed the second easement which is located at Kelham Island, just off Ball Street bridge

The easement is formed of concrete which is set in to the face of the weir.  A notch is cut in the crest of the weir to allow the water to flow down the easement

Work is still progressing at Brightside weir with the base being poured and the walls being poured this week.
