I've fished the bottom lake a few times and the top lake once. The bottom lake holds the bigger fish, had some big fish off the top with mixer down in the reeds by the house and some lovely koi nearly hitting doubles. Ill be popping there this winter for some of the nice perch!Not too expensive either.
This is a really nice place, I've been 4 times and caught enough to lose count.
Bread on the top works best for the bigger ones, bit bashing with a 3m whip is also a must.
Pre-book a full english, toilet on site, nice grounds and out in the middle of no where.
