Core trench and elevation question - 12/03/21 08:01 PM
Hello everyone, this is my first post on the forum and after lurking for months I decided to say hello and become part of the community. I own a 50 acre farm in NW Florida that used to grow peanuts, and on one side there are two hills that form a small valley and stream that flows with any rain at all. I decided to build a 1-acre pond in the middle of this area for a couple of reasons. The ground there stays muddy and is hard to work so I figured it was a great spot for a pond. After having several quotes of $25-40,000 I have decided to build the pond myself. I have a 30hp John Deere with an FEL and a box blade, and so far I have been using the box blade to move all of the topsoils to the sides. Under the topsoil is really nice red clay, very compacted, very hard, and should make a good liner. The high end of the pond is about 6-8 feet higher than the low side, and I plan on making it a kidney shape where the rounded side of the kidney is about 65% dam. My question so far is, should I start the core trench at any elevation change at all, or is there a certain depth where I should begin putting a core trench in? It's a pretty gentle slope, so I was unsure where to start digging the trench. Thank you for any help!
