hmmmm... chod is the way to go here! but b4 it was invented a lake i fished was similar to yours, all i did was spod the hell outta it, foam up the hookbait and cast into the spod! cought loads doiing this, however it then dawned on me that not all the spod hit the bottom,it must've just lay in the weed at all different depths? so on one rod i used a lightweight lead and long hooklength,to hopefully just sit in the weed with the spod! it worked a treat! but without an underwater camera i could'nt be 100% as to what was going on amongst the weed, but i cought on this method till the weed dissapeard a few years later, i also bagged up on a freeline, again i cought some good carp doing this, although dont use it in the wind as this can be a real problem.
