My normal fishing hole here in Texas is a private lake, roughly 22 acres. Very remote, extremely little fishing pressure. Up until the flooding rains water was brown, and you would catch a keeper size bass literally every cast. Since the rain it has risen about six feet and settled. Deepest point is roughly 12-18' Now 99% of the lake is covered with very thick hydrilla. Fished it both Saturday and Sunday and only caught one little bass each day. Upper 90's during the day. Any tips on pulling some bass out?

Goto the bottom!

I tried cranks, three colors of jigs, swim jigs, all my worms. The vegetation is as thick as it could possibly be

I have to agree with Catt.  I have a lake that's typically about 12'-15' deep and is about 40 acres.  Haven't had much luck with the hot temperatures and rising waters, but I stumbled upon a dip that dropped to 20 foot and that made ALL the difference.  The largemouth still weren't hitting (could be the new jig I was trying) but I got a few excellent catfish off some chicken liver/chicken blood baits.  got a couple white bass off the shore in a heavily shaded cove too.
