There are two pools that side of the road bud. We used to fish the pool further up for good perch.
Im not 100% on who it belongs to, we presume it was the horse riding schools land. We never had any complaints from anyone fishing there, I would have a walk further up the hill & your find the smaller pool, there is a stream quite close to it so keep an eye out for that & your soon find it. Its alot easier to get to from the top of wendover as theres a path that leads onto the field.
I use to do bits of work for one of the chairmen for oldhill, im going to try & get in touch with him again & see whats happening. In my eyes it seems the place was alot better when it was free to fish.
