Cogra Moss Reservoir


Cogra Moss is an artificial water body near Lamplugh in West Cumbria. During the summer of 2013 we discovered a buried tunnel whilst completing statutory ITIOS (In The Interest Of Safety) work.

On inspection an independent engineer suggested that the tunnel should be concreted up or have a permanent access made available to it. Further work was also identified to address the lack of a siphon facility should the reservoir levels need to be reduced in a planned event or during an emergency.

The other approach suggested by the engineer was to discontinue Cogra Moss.

The engineering report left us with two options:

  • Fix the reservoir to satisfy all the ITIOS notices, or
  • Remove the reservoir and return the area back to its natural state.

It’s worth noting we have a legal obligation under the Reservoir Act 1975 to complete one of them.

We completed further surveys and cost benefit analysis to decide the most appropriate future for Cogra Moss. We also received communication from the local community in support of retaining the reservoir rather than returning it to a natural state.

After listening to the views of the community, alongside our own assessments, we have decided that the best course of action is to retain the reservoir and carry out the work required to satisfy the ITIOS inspection.

Drop-in and find out more about our plans

We're due to start work in spring 2018 to carry out the required elements of work which will allow the reservoir to be retained. There will be some temporary disruption while the work takes place, so the project team are holding a drop-in session where we can provide further details and answer any queries you may have. 

Our work will ensure the integrity of the dam and the safety of those living downstream, whilst also preserving an amenity that is integral to the community. 

Pop along and speak to the team.  We'll be at Lamplugh Village Hall on Wednesday 7 March between 11.30am and 5.30pm.
