It sound like to me that you need to hire a contractor with just a specific piece of equipment and do each part seperatly and pay each guy as they do ther part....Get a guy with a dozer to clear the land. Then get a guy with a trac-hoe to cut the core, BE OUT THERE WHEN HE CUTS THE CORE, it is very important to be out there on every step when he cuts the core...While the core is being cut you need a dump truck and another excuvator to fill the dump truck with clay. Then you need to Back fill the core as you are digging it out. If not as go down 20 feet the trench could cave on you. You will always need a dozer around to do all the Misc. ends and outs of the job. Once the core is cut and back filled with GOOD clay. You will need to get some cement and a transit to place the stand pipe. Can't be an inch off on this. This will dictate how your water is going to back up. Use the cement to make a base for the pipe, then put wet cement all aound the base of the T of the stand pipe. Let the cement dry and slowly start putting dirt around the pipe. Gradually start building up your dam, use a sheeps foot roller to help in compaction. When the dam is finished the back side will need to be covered with grass seed and hay. Now when you get ready close the gate on the stand pipe and let the lake fill up....
Cecil you might need to guide each of these steps mentioned above to have your project succesfull.....
