20 Metre Weir Boom Installed at Knockvicar

7th February 2011
20 Metre Weir Boom Installed at Knockvicar
Waterways Ireland, as part of a planned inland waterways programme of improvement works, has installed a floating Weir Boom across the weir at Clarendon Lock, Knockvicar on the Shannon Navigation.

Installing the 20m boom was initiated with assembly of the boom off-site in Rooskey. In early December, the drilling for the piles was facilitated by floating a piling rig to the site on pontoons. Piles are required to hold the Weir Boom in place. The boom was then floated to the site and secured in place. The works cost approximately €55,000.

Installation of the boom improves the amenity at Knockvicar in addition to lock gate replacement and upgraded lockhouse facilities which have been completed by Waterways Ireland in recent years.

The Weir Boom is a preventative measure installed by Waterways Ireland to protect boaters and their craft from being drawn over the weir. Space has been left to allow for the passage of canoeists. There will be no environmental impacts on fish or other wildlife from the installation or operation of the Weir Boom.
