Not sure if this is close enough, or what your looking for...
I have fished it once (Haddon lake) 3 or 4 weeks ago, and carp were being caught in the deeper swims.
As the site says, there are four lakes and I'm sure if you phoned them they would tell you more about the fishery.
Be warned about the approach road! You turn into the entrance for Santo's Higham Farm Hotel, then take a sharp left straight away (sign-posted fishing). This is a single track road and is quite long and VERY steep!
There's ample parking and you hardly have any distance to walk to get to any of the lakes.
