Leak in the bed of the canal into a culvert used to drain down the canal. They ended up dumping a few tonnes of clay to keep things open until winter stoppages comes around.

I understand the use of culverts, but why plug holes? I needed to drain a pound on the Rochdale to cut a spring mattress off the prop, seemed easy enough.

The drain paddle is on the opposite banks, with a culvert running under the bed of the canal and towpath, so it had somehow found a hole in the bed of the canal into the culvert.

 

Draining the canal causing a whirlpool, so they dumped the clay in the bottom as a temporary repair to plug the hole and stop the leak that was going into the park/tennis courts.
