Some more info on this place
A bailiff told me Ronnie rig with small 12mm pop up and just a a small amount of freebies (6-12 boilies) around said hookbait but cant help thin that 90% of anglers are using and suggesting Ronnie as its the "Vogue" rig this year.
The lake bed is littered with rocks/bricks/building rubble , very snaggy, this was caused many years ago when the put the 3 islands in, so fishing close to the islands is a good way to snag up and go out in the boat to free up
Canadian pondweed is rife, its really hard to find a spot to fish due to the weed, clear patches are few and far between.
As for getting a Deeper, sorry but thats a £200 spend on yet more kit, feels like throwing good money after bad at this stage!
The lake is long with the islands mid point from most of the margins depth starts at around 3ft, soon drops to about 6-7ft then hits an "underwater channel that runs round most of main body going down to 12-14ft before getting to what they call the "road" running out to and intersecting the islands and that is about 6ft deep, but with lots of snags either side of the road, the lake has an inlet from larger Ski lake and an outflow into local canal, the inlet flows into the back bay that is less snaggy, a bit more shallow and less weedy
I have put a pic up the red line sort of gives an idea of the deeper channel that runs round main body, the green lines show whats called the road
