Cranham Trout Farm?

After dropping Freya at the station for her 10.00am train back to Durham, and a quick shop and a blast of house work, Mollie and I braved the cold and went for a wander up and over Cranham hill.

We think this is a trout farm, access is definitely prohibited and it is very well tended so iris a farm of some sort, or they are preparing it for rural ice rink?!?!
