That's very surprising and I would have thought it would require some significant event to achieve that. It was fine at the weekend before the massive storms. You aren't on the Rushall flight are you? JP Link to comment Share on other sites More sharing options...

If it is 12in down then basically there is no water in it. 1 Link to comment Share on other sites More sharing options...

haza Posted May 31, 2018 Author Report Share Posted May 31, 2018 im near brownhills im looking at the waterline now ..and i would say its down more then 12 inch ..if i knew how to put photos up i would ...why would i say such a thing if it was not so ,, Link to comment Share on other sites More sharing options...
David Mack Posted May 31, 2018 Report Share Posted May 31, 2018 I had in mind that the Wolverhampton Level was about 50 miles, and the Birmingham Level about 60, but Wikipedia suggests both are about 10 miles less. Perhaps my figures are for the full extent before the closure of various arms and branches. Link to comment Share on other sites More sharing options...
matty40s Posted May 31, 2018 Report Share Posted May 31, 2018 I remember being in Paddington basin in 2010 when someone opened all the Camden lock paddles during the night. Next morning the pound was almost 2 feet down and lots of damage caused around Camden locks to the towpaths and ad joining properties. That pound including Slough arm is 22 miles Link to comment Share on other sites More sharing options...

I was boating in a thunderstorm there at 3:00am on Sunday morning and it hammered down Losing 12" of water in such a short time is very unlikely There is an overflow on the towpath side opposite Silver Street/ Tescos at Brownhills. Can you see a foot of concrete between the lip of that and the water level? Richard Link to comment Share on other sites More sharing options...

Canalplan gives Longwood to Engine Arm as 31.31 miles, adding the bits is probably another 7 miles or so, so a bit under 40 miles I would say. A lot of water at 12 inches down, particularly as the level was above normal on Sunday I would say. Has the OP spoken to CRT? Link to comment Share on other sites More sharing options...

Lots of mine workings under that area, although I'd expect the OP to be asking about the flow on the canal, not the level if the canal was draining away Walsall locks is another possibility, they';re still quite a long way from Brownhills Link to comment Share on other sites More sharing options...

Can you see a foot of concrete between the lip of that and the water level? Richard We were moored there overnight. Woke this morning with boat aground and listing. The weir board was showing about 3 inches. We left this morning for Bentley Bridge. The gauge board at the Fingerpost Pub would indicate the level about 6 inches down and where there was piling so you could see the watermark would seem to confirm this. I spoke to CRT this morning who said they were aware and investigating. Terrible journey to Bentley Bridge, bumping over stuff in the bridgeholes and filled 3 bin bags with stuff off the prop. Worst thing was striking something solid and taking a chunk out of the prop. So back into the dry dock in a couple of weeks. Link to comment Share on other sites More sharing options...
RLWP Posted May 31, 2018 Report Share Posted May 31, 2018 There you go - I'm wrong and the OP is right I wonder where all that lovely water has gone? Richard Link to comment Share on other sites More sharing options...
MoominPapa Posted May 31, 2018 Report Share Posted May 31, 2018 (edited) Just because it's 12" down in one place, it's not safe to assume it's 12" down over the whole 40 miles. It'll take a long time to drain 40 miles of shallow, meandering canal through a point leak. I just googled "hydraulic gradient" and was boggled, but my intuition is that the canal could be empty at one point and still full only a few miles away, at least for a while. MP.

Richard No, you were not wrong. The level was down but it seemed 3 inches to me going by the amount of board showing at the overflow weir at Brownhills. At Pelsall it was 6 inches down and it is still 6 inches down at Bentley Bridge. Don't know where the OP is moored, presumably the Longwood side of Brownhills.

If it was 3 inches down at Browhills this morning and it is 12 inches down now, the level is going to be empty by morning you would think. Link to comment Share on other sites More sharing options...

No, it's only 6 inches down, and has stayed at that since 11am. We'll see in the morning if it's stabilised or hopefully recovered. Link to comment Share on other sites More sharing options...
