I had a wander round last year with a mate. We did actually drive up to the house, turn around in the yard, back to the car park and then wait around to see if anyone would 'apprehend' us so we could ask if it was ok to look first, but after waiting for some 20minutes with no-one around, had a wander anyway. Our choice was to go elsewhere as we couldn't see anything that interested us.
It looks a nice set of lakes, some bubbling, tree surrounded, but no showing fish on the surface at the time.
I know my mate Big Dave has fished it in the past, and he never caught anything much bigger than doubles, I think his biggest was around 15.
