jdk4174,
You are right about the water levels. Unprecedented low water in many ponds.
Regarding the boat ramp, my thoughts would be dependent on what size boat you will be launching. If small, relatively light, shallow draft boats, then the ramp can be fairly simple and inexpensive. If launching tournament bass boat and/or ski boats then the ramp would have an entirely different design.
Just looking at your picture and having some experience with equipment as a DIY person, I'd say in a matter of less than two hours on a small dozer, you could have a ramp entirely suitable for launching small boats. For larger boats, concrete ramps and deeper water are desired, if not required.
