I live very close to the Stroudwater - around 200m away (near The Ocean)
I quoted recently about the damage at Dudbridge locks - the gates only lasted about 3 weeks before the site flooded and massive damage was caused to the lock infrastructure - it was quite clear to me that this was due to a really poor design of the culvert underneath the adjacent main road - with no screen cleaner, the culvert may have been able to take the flow (debatable), but without one, it was always going to block up. I appreciate that it was after heavy rain, but the Frome has been nowhere near as high as it has been over the last few years (it comes up my garden, so I am well placed to comment). The rainfall on the day of the damage was less than half of that bad day in 2007 when everything went under - I hear talk of a 1in a 100 year rain scenario, but this was nowhere near that.
Lots of residents are against it as it costs them money in their council tax - its a large borough and many people who are simply not near enough to get the benefit. What benefit for instance does someone living in Wootton under Edge get from the canal?
I think with Stroud District Council in charge, there is a very poor chance that the canal will be restored properly.
A good example is the swing bridge at The Ocean - this project ran massively over time and (presumably budget) - SDC sat back and watched their contractors build the bridge at the wrong angle - meaning that any high sided vehicle would impact nearby property. The remedial works to this cock up took several months. In addition, they put the control mechanism on the non towpath side where there is no mooring (I know this is not unique, but it is inconvenient and they could have done it right). Probably worst of all, they allowed a mechanical/hydraulic system to open the bridge to be wrongly designed and constructed - to the point of being almost unusable. This was acknowledged and a better solution sought - but I understand that it has been recently signed off as being acceptable. Incredible!.
I should also mention the tunnel under the adjacent railway - I have some experience of tunnelling under Network Rail assets and can only say that the red tape and the massive delays may well scupper the whole thing. Network Rail are not interested in the canal - if they even allow it to be rebuilt, they will probably insist on managing the whole project themselves and will use their own contractor - but to get to this point may well take years and you can only guess at the price.
I think this project may be decades away, but sadly, I think that many parts of what have been done are simply not up to standard.
