Please read the e mail below reference the proposed works at Carr Mill Dam. This is the first official communication we have received from Canal and Rivers Trust regarding the works, and as you will all see the position/dates are as yet unknown. Any further correspondence or updates will be posted on the Website to keep all our members informed as much as possible.
Firstly, I’d like to apologies for the time it’s taken to get a response to yourself about the works planned at Carr Mill Dam. As we have previously discussed this maintenance project is in the very early days of being planned, and we are yet to appoint a Project Manager, who would do normally this type of stakeholder liaison. In the meantime, I have put together some points for you to share with your membership.
The Canal & River Trust owns Carr Mill Dam and is ultimately responsible for ensuring the structural integrity of the structures associated with the reservoir. Large reservoirs are subject to stringent statutory control under the Reservoirs Act 1975 (as amended by the Flood and Water Management Act, 2010), this is there to assure the safety of the public below dams. The Environment Agency is the enforcement authority for reservoirs in England.
Unfortunately one of the twin draw-off valves has failed and is inoperable. Emergency drawdown would be by means of the single remaining valve (rather than two) which has a lesser capacity, but it be can be aided by auxiliary pumps. However the Supervising Engineer is content with the management of the risk in the short term, but it needs to be fully operable before the next inspection. The intention is to replace both valves at the same time, as it is only a matter of time before the second one also becomes unusable.
The current plan is to drain down the reservoir to provide safe access to replace the valves. The use of divers has been discounted on safety grounds. A fish rescue will be needed along with a plan on where to hold the fish and subsequent restocking. The Project Manager normally considers other opportunities to carry out other work which may benefit the reservoir. I would advise you to write down any suggestions, and when the Project Manager is appointed then you can discuss it with them.
I hope that this helps.
