Technical stuff

Work is moving on at Steelbank; concrete blinding has been poured to stabilise the holes that have been dug with the next phase being the installation of steels to create the two-flight pass.


The two flight Larinier (named after the man who invented the baffles that sit in the pass) being built at Steelbank/Packhorse weir and also at Brightside weir will have a resting pool (see schematic below) and  baffles disrupt the flow of water which makes it easier for fish to ascend the weir.
