Upper tamar reservoir has 2 sheds, one on the Devon bank, the other on the Cornwall bank, they are basically a concrete base and a shed on top lol. Good head of carp in there 👍
I think Stafford Moor fishery has a lake with lodges on and a decent fish, might be worth having a look 👍
Also check the catch app mate, pretty sure you can change the settings on accommodation 👍
