Funnily enough I contacted the EA six months ago about the first fish ladder on the River Sheaf in Sheffield being completely blocked by cobbles and gravel from floods, and offering to help shift it in my spare time - as salmon are now in the River Don just downstream of Rotherham it seems a good idea to keep the upstream passages clear, and I have waders.
Needless to say I was asked not to do that, for insurance and liability reasons - and no doubt the risk of Weil's disease. The guy did say they would look at it, but so far they haven't done anything. It probably is a bit mental with Covid and so on, so I can't say whether they just binned it or it is 'on the list', but it's frustrating to see when it's so productive. It would take a couple of people about a day to do it.
I watched brown trout spawning last week a few hundred metres upstream - right outside the Wolf safety lamp factory, ironically 😉
