This has been on the news recently, and I have took the following pictures and text from Birmingham Updates who have a page on Facebook. It relates to a section of canal in Gas St.......
"Central Birmingham canal drained to investigate a ‘significant’ leak.
Canal & River Trust are currently draining a 200 metre stretch of Central Birmingham canal between the Mailbox and Gas Street Basin to investigate what appears to be a ‘significant’ leak.
The trust launched the investigation and drainage operation following reports of water escaping from the bottom of a historic canal aqueduct, which was constructed to carry a now disused railway under the canal, now in the ownership of Network Rail.
Boats currently moored in the affected stretch have been moved further along the canal. A specialist fish rescue team are working to remove thousands of fish - 7500 fish have been relocated to other parts of the canal so far.
Hayley Harper, from the Canal & River Trust, said: “The leak appears to be quite significant so we need to know as soon as possible exactly where it’s coming from. The only way we can know for sure is to drain the canal and thoroughly inspect the aqueduct. I can’t remember the last time we drained this part of the canal so it will also be interesting to see what other changes have occurred to the canal bed as well as finding out exactly what has caused this leak.”
The towpath remains open for the time being and the canal will reopen as soon as possible."
