We went over there for a walk and a pub lunch in Peaslake today.
There was quite a bit of water running down the road, from the top of BKB, as we walked to the pub, and it wasn’t raining at that point.
It started raining during lunch, and there was even more water on the way back to the car, at about 14:00, but it I wouldn’t have described it as flooded.
When we first arrived (11:30), a couple of MTBers were just getting back to their car and didn’t seem too muddy at all – although I’d probably give it a miss because the muddy sections we did walk past were very muddy (Wouldn’t want to cut the trails up any further)
