Hi Mr. Ackerman,
I don't know why there is such an abundance of grass + weeds, but usually things like this in nature cycle year in and year out. Many of our winters we have the grass die off, some and it grows back. This kind of controls some of that. But we had a very warm winter last year, changing many things. This gave the grass more growing time, so it is much higher and lush. I am not a scientist. Just my guess.
What I can tell you is many ways that you can fish in the grass with lures. One start using single hook lures like jigs, you can even remove the treble hooks off your mirrolure. Then replace it with a single hook. I do this all the time. It picks up less grass and is very effective. You can use more topwater lures where the grass is growing almost to the surface. Or use the same Cajun Thunder float rig, but just tie on a Texas rigged jerkbait, shad tail or shrimp instead of the mirrolure. A Texas rigged bait is where the hook point is slightly embedded in the bait (photo attached).
Last, you can actually buy weedless jig heads and place the plastic bait of your choice on the weedless jig head. This will all prevent grass from fouling your bait too much.
