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 make modifications to be able to effectively reduce the reservoir levels when necessary.

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 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 decided that the best course of action was to retain the reservoir and carry out the required work so it could continue to be used as a beautiful area enjoyed by the community.
