The Atherstone flight was built with side pounds. These were out of action before I was using the flight (only lock 6 side pound working in my experience). I would love to have seen them operate with side pounds working. Rog I think they have been out for a long time. I think a few were working when I first went through, probably mid 70s, but of course they don’t help to save water if just one or two are operable in a flight. I was once told that originally they had top gate paddles in addition to the top ground paddles, and the removal is why the fill and drain rates are so mismatched, but that might just have been gossip.

Canals were privately funded so most if not all do not have a public right of navigation. Seem to recall reading somewhere that there was a PRN on canals but Thatcher extinguished it.

The Atherstone flight was built with side pounds. I was always of the belief they are called 'ponds' but the term appears to be interchangeable. Or maybe there is a difference between a 'side-pond' and a 'side-pound'. from Wikiwikiwikikikikikif'tang: "A side pound is a particular type of extremely short lock pound, which is extended sideways to make up for the short distance between locks so as to avoid excessive level fluctuations. An example of this is the Caen Hill locks on the Kennet and Avon Canal. Climbing the hill that leads to Devizes requires 29 locks. The first seven and the last six have conventional pounds, but the middle sixteen have large side pounds, enabling all 16 to be fitted into a distance of around 0.6 miles (1.0 km). Serving a similar function are the side ponds on lock flights such as the Foxton flight. The ten locks are organised as two staircases of five chambers each, where each lock can discharge water into the pond below it and receive water from the one above it. Although connected to the locks by sluices, they are still often called side pounds, as they are maintained at the level at which an intermediate pound would be if one were present. The term side pond is also used to refer to a water saving basin, which is maintained at a level between the upper and lower level of a single lock. Most of the locks on the Grand Union Canal between Whilton Locks and lock 45 at Bulbourne, the junction with the Wendover Arm, were built with two such side ponds, although they are currently disused. Perhaps TB has an expert on canal furniture and terminology...

I wondered if, with the side pounds (ponds) operating fully, the locks would fill considerably faster,as half the lock would fill from there. My guess would be that TonyDunkley may have worked Atherstone when they were in full operation ... he may care to comment. Rog

Credit where it's due ... I think he'll have been through if he's been boating since he was 8

I’ve always called them side ponds.
Im not sure the side pond can speed up operation and you have to know what you are doing and close the paddle when the lock is 1/2 full or 1/2 empty. I just can’t see it being feasible for the average thick noddy boater.

We used to use the one at lock 6 everytime (shown by a BW guy first time we came through) and felt it speeded up the filling process. But then one day there was a sign saying no longer in use and the paddle gear was padlocked. Rog

To minimise use of water (which I think was the original point) you start to fill only from the side pond. Once the level is equalised you close the side pond paddle and open the top paddles. Or of course you can open the side pond and top paddles simultaneously. That will speed up the early part of the fill but not minimise use of water. Of course you have to remember to close the side pond paddle at the appropriate moment, otherwise the lock will never fill and water will be wasted. So yes you can use it to speed up the first 1/2 of the fill, but since it is the second 1/2 that is the slowest, it doesn’t make a massive difference.

Are the side ponds still used on the Droitwich?

Maybe you have been listening to TD too much?
