Bar Hill's Wetland Project
Starting early this year (2014) a project was initiated to improve the effectivness of the balancing pond that forms part of the wildlife area adjacent to Field View and is part of the water control infrastructure associated with Dam Brook (the stream that runs through the village). The plan is to create a slot weir to throttle back the flow of water in storm periods thus better utilising its storage capacity.
The
project brief was issued in July 2014 and invitations to tender were issued on the 1st of August.
The Design of Detention Basin Weir has been agreed and work started today November 6th 2014. I will post dates and other details as they become available.

This drawing shows the areas where the work will be taking place. Consideration has been taken of the need to provide habitate for the watervole population and you can see that there is also a newt pond.

The rain on Friday made the wiring together of the gabion mat quite tricky as you can see in the pictures below but the weir does seem to be working as expected and the heavy rain was a good test of it. These pictures were taken by Rob Mungovan who is the Ecology Consultancy Officer and has managed the project.

Work on the Slot Weir 13th November 2014
The work is progressing well after a false start on Tuesday(11th) when the contractor realised that the digger ordered was too small for the job and a bigger one was needed. There was also some concern that the digger would get stuck and need expensive extraction. Some work was done to see if hand digging of the post holes was viable but the going was too tough! Today a bigger digger was delivered and the work got underway at around 7:30am - I wasn't there to see so have taken it on trust. The first picture was taken at about 1:30pm today and I will go back later to take some more
