On a 'U' shaped pond, do you core trench the entire dam?
I'm planning to hire this out, but I want to know what I'm talking about so that I can properly convey the message (without sounding like an idiot) to the contractor.
The property slopes gently from north to south, so everything except the northern shoreline will essentially be a dam.
Should all 600 feet of the dam be core trenched, or just the portion at the southern end that has 16 foot deep water pushing against it?
Side notes:
I'm planning to dig a 2:1 slope starting at the northern shoreline to a depth of 6 feet, and then the southern shoreline (dam) will have a 3:1 slope and it will be dug out enough to achieve a water depth of 16 feet.
