Funny you should pick this area out. When I saw it in the early spring. before the cover started to grow up and hide everything. I thought it was the most littered length of river I had ever seen. The litter, right up in the trees shows how high the flooding can be.

How do you know about the crays Craig? Have you seen them recently?

The rother was one of the most polluted rivers in Europe at one time, and we're not talking that long ago either. It would be an amazing turnaround if there were native white claws in there. I know the river was cleaned up a few years back and fish re-introduced but I don't know what species/numbers etc... I'd be interested to know though if anyone out there has any info.

White-clawed Crayfish
The White-clawed crayfish, a relative of the lobster, is the only native freshwater species of crayfish in the UK. They are olive green to brown in colour, and adults are up to 12cm in length. They were once widespread in clean, calcareous streams, rivers and lakes in England and Wales, but since the introduction of the Signal crayfish from North America and the crayfish plague that they bought with them, numbers have fallen dramatically and many populations have died out. The Signal crayfish was introduced into Britain in the 1970s for the restaurant trade, but they soon escaped and began breeding faster, eating faster, fighting harder and cannibalising our native white-clawed crayfish. The North of England is one of the last strongholds of the white-clawed crayfish, and the River Rother here in Chesterfield is a very important habitat for them locally.
