Looking on the satellite view of Google Maps is misleading as the lake is more than a featureless muddy puddle! The red water (related to the soil) means the fish have a beautiful colour, really golden with bright red tails. The swims are well made and there's cover either side of most meaning the margins are very carpy. The water level was very low, I'd estimate a good 70cm lower than usual (a lot for a smallish lake).
Fish wise, they're a crafty lot... Most fish fell to luncheon meat or chickpeas but presentation (especially the size of the bait) seemed to be critical. I found that fishing two small cubes of luncheon meat on a hair rig over handfuls of hemp mixed with sweetcorn and small trout pellets lured in the bigger fish. The smallest hook and the lightest tackle you can get away with is the way to go.
The fish really started showing on the surface around 2ish so we tried our luck with soaked dog biscuits. Again, the fish really showed their skills at spitting out bait: at one point, I had 5 or so decent size carp feeding freely on biscuits n the reeds literally 1/2 a meter from my feet. Every time they sucked in a baited biscuits it'd be causally spat out and the 5 would spook off only to return a couple of minutes later and the process would start again. All in all, I'd say we got around 30 or so fish (common and mirror carp) between us, most being 5lb and under and a couple up to 10lb.
Verdict? Well worth a visit, although I'd wait till be get some heavy rain so the water level is higher. The fish are in really good condition but I suspect it gets heavily fished - not a problem if you enjoy a challenge and don't want to catch monsters!
