What's this?

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.

Anyone, the structure, not the tree.

We had something very very similar to this in the village I previously lived in . Old estate lands, very low lying and quite flat. There was a succession of sluices with associated spillways, to manage beneficial land flooding to bring in nutrients silt for the farmlands, protect our village from immediate inundation and also protect 2 other villages closer to the thames basin from devastating floods when the water tables rose to ground level. In our case they were originally constructed by a local monastery,  but taken over by landlords and the big estates on dissolution of monasteries in the middle ages.

Yours are missing drop in boards in the left hand channels, right hand channel allows overload to spill out.

Sound explanation, could it also be a Leat for a water mill or similar, or even some sort of fish holding pound? I agree, there would be some sort of drop/stop boards needed.

Sheep dip/wash comes to mind that can be drained down.

 

Granted a better os map would probably be quite informative.

Unfortunately all the information I've got, not even a rough location on this one.

Possibly in your case yes. The monastery in our area had both carp ponds and a mill, but these were higher up stream and both linked in to the system talked of earlier but not influenced by it

Makes sense, do you think the two wooden posts behind the brickwork in the left hand channel would be part of the structure to accommodate drop/stop boards?

Just seems a bit odd having a slope/cut in steps on the right, obviously it could be silted up over time from a watercourse but it's all proper brickwork which indicates something a bit more important building wise.
