One down, four to go!

The first of our five fish passage solutions has been completed at Lady’s Bridge near the Wicker in Sheffield.  This is a baulk type easement which is set in to the face of the weir with a notch cut in the top of the weir to allow the water flow.  This changes the flow of the water which allows stronger swimming fish to get over the obstacle.

 

Works begin on Kelham Island this week to install an easement similar to the one pictured above and then the contractors will move on to Burton Weir near Norfolk Bridge.

Steelbank is having the walls of the pass poured this week before they reinstate the stone sets on the face of the weir and install the Larinier baffles.

It’s all about the water!

At Brightside weir it’s all about water management!  The sandbags that were in place to dam the weir weren’t as effective as they had been at Steelbank and so piles have been driven to create a coffer dam instead.  Hopefully they should be able to start breaking out the weir by the end of this week.

Work has really come on at Lady’s Bridge and, if the weather stays fine, it should be completed by the end of next week.

As you can see in the photos below, the concrete easement has been inserted in to the face of the weir and the contractors are currently re-laying the stone sets around it.  The easement is pre-cast off site and once installed with a notch at the top of the weir will allow stronger swimming fish to ascend the weir.
