Captain Pegg Posted July 10, 2022 Report Share Posted July 10, 2022 (edited) I think Atherstone may have pumping capability but fundamentally every canal will have a degree of leakage, it’s not practical to make them 100% impermeable. That’s not to say there isn’t any specific leakage that could be fixed but I don’t think that’s the issue at hand. The issue is one of prolonged dry weather on groundwater volumes and the effect of evaporation in hot weather on a canal that is only directly fed from natural water resources. It won’t get solved until winter because groundwater levels will continue to fall until then. It seems there will need to be a careful balance in feeding the Coventry and Ashby without spreading the problem to the Oxford.

The gates leak. CRT have been and said that they have fixed it but according to the Vlockies there is a certain pound which still runs dry 1 Link to comment Share on other sites More sharing options...

CRT have been and said that they have fixed it but according to the Vlockies there is a certain pound which still runs dry I've seen the pounds between locks 3 and 5 running low but the integrity of the long pound from Coventry is maintained by the seals of the gates on the top lock. Running water down to a low pound further on will use some water unnecessarily but probably not particularly significant in the context of the size of the pound above Atherstone. It's not a flight renowned for dry pounds as far as I know, and I've never encountered anything immediately impassable there. There is something that is different this year which has tipped the balance and it seems that it's not leaky gates at Atherstone. When was the last time that these canals had water shortages? I don't think canals deserve sufficient public money that they are bulletproof in all conditions, but yes a maintenance regime to keep gates sensibly water tight is feasible.

Certainly the pound below Baddisley Wharf was very low 2 weeks ago. Nb Squire and I were stuck for at least 45 minutes as we tried to pass each over. Had to run water down from pound above untill the boats in the small marina started to lean. According to a boater there it has been like that for a couple of weeks 1 Link to comment Share on other sites More sharing options...
BEngo Posted July 10, 2022 Report Share Posted July 10, 2022 In normal operation the not backpumped at Napton surplus water coming from Napton and Hillmorton, and which is not drawn down Calcutt, ends up in the Coventry to supplement the ground water etc. The water has a long way to go to do this! At the moment I suspect that evaporation, transpiration by trees and leaks on the 'morton and Rugby pounds are losing all of this water before it gets near Hawkesbury, so the Coventry Ashby pound is suffering. Running water from the Oxford summit reservoirs is possible, but it will take a heck of a long time. 1 Link to comment Share on other sites More sharing options...

Tracy D'arth Posted July 10, 2022 Report Share Posted July 10, 2022 Its peak Corn growing season along the Ashby, I bet the huge field irrigation pumps are sucking the canal dry. Link to comment Share on other sites More sharing options...

The amount of water lost due to evaporation is a lot more than people thing, I know by how much I have to top my pond up by. between 3 and 4" over the past 3 weeks and I don't have any leaking gates Link to comment Share on other sites More sharing options...

Jen-in-Wellies Posted July 10, 2022 Report Share Posted July 10, 2022 It's the lack of visiting boats on the canal. If the water level is low, less boats visit, especially the deep drafted ones. Boats displace water and raise the level, so the water level drops even lower, so even fewer boats visit and those already on it leave, making the level lower still, until any boats that are left are stuck on the bottom and can't leave at all. 1 Link to comment Share on other sites More sharing options...
MaryP Posted August 8, 2022 Report Share Posted August 8, 2022 Not too bad today, but still low. Able to move keeping near the middle as far as possible.... Link to comment Share on other sites More sharing options...
Col_T Posted August 9, 2022 Report Share Posted August 9, 2022 We came off the Ashby on Sunday. The first 2 or 3 miles after Marston Junction were the worst, with levels low enough that anything much above tick-over wasn’t really viable as it led to breaking wash and the propeller stirring silt. It seemed as though the nearer we got to Shackerstone the more water there was. Link to comment Share on other sites More sharing options...
Captain Pegg Posted August 9, 2022 Report Share Posted August 9, 2022 (edited) When I travelled up and down a couple of weekends ago I found that Marston to Hinckley was OK and I could average 3mph on that section and also between Shackerstone and Snarestone which has been dredged. The middle section was slow going and was down close to 2mph average at times. Someone else did remark to me that the south end was the worst of it but I didn’t find that to be the case for me.
