I was told of this trout fishery a few years ago by the chap at the Bakewell fly shop.
As far as I can recall it was in the Matlock Bakewell Chesterfield triangle.
I found it once . (Stored it in sat nav) now defunked.

It was on the right at the bottom of a hill just before a right hand bend then the road climbed a steep hill .
The fishery itself had a smallish trout lake perhaps 5 acres with 2 course lakes
beyond.
There was an old large caravan used as an office /club house with parking next to it.
anyone know of this place and does it still exist.
