Billy, that's a loaded question in so many ways.
As a consultant myself, it would require a good evaluation of what's going on right now, vs 3 years ago.
As for common mistakes, there are many. One of the biggest is thinking you can tell a group of owners what needs to be done. Earning the trust of those will be important or you will be spinning your wheels.
Not trying to be negative here because I think you're at the right place to get some good info.
If you would share some history about your impoundment such as what species are present now, and how has the size structure change over the last several years. Guessing you've got a bunch of small bass now??
Please share the issues.
