Okie, I gotta agree with Ewest. I'm not sure the results add up. You are making some pretty good size financial commitments. I believe I would consider having an electroshocking boat come in. The Pro's are able to give you a better assessment than you can do for yourself. It sounds like you may have a good fishing hole but that can change. I have gotten a pretty good education by screwing up some water holes. I'm probably gonna screw up a couple more by bulling ahead.
I'd stop and think about it. You have good fishing now and with a real management plan, it could continue and get better.
BTW, not everybody has been able to whip Oklahoma and North Texas turbidity.
