What happens here

The creator explains the unique challenges of excavating a clay-bottom pond. He emphasizes that the primary goal is to remove only the accumulated sediment (muck) that has washed in, while carefully preserving the underlying clay layer. Breaching this clay layer could lead to the pond draining into the groundwater basin, resulting in significant problems. The operator must therefore use the excavator's bucket to 'feel' for the firm clay bottom, ensuring only the softer, unwanted material is removed.

Goal: Develop a careful strategy for sediment removal in a clay-bottom pond.

I see. Is that your rip wrap, Tim? [Applause] John can come pick that up. I think was that from the Bayport job? door's job. Yeah, you're a couple jobs behind there, Sam. I don't know where the key is, but I opened everything else up. Should be right under here, but I'm blind, so I didn't see it. See it under here? I didn't see it in the little cubby. Did you look behind the seat? I didn't look behind the seat. Look in the engine compartment, though. Or in the glove compartment or above? It's not in here. Okay. or above the uh So, our policy is we always leave a key on the machine cuz if a guy brings it home and then that guy runs late or that guy calls in sick, there's always one guy that leaves it in a different spot than everybody else. You know, that's why codes are nice. Everybody can know a code. Yeah, that's why I buy my machines with codes. It's not cuz of the extra security. It's just cuz then nobody can have this problem. Honestly, I'm not sure that that is more secure. So, this is a claybottomed pond. Now, our job is to go in and just to remove the sediment that washed in from the parking lot, but we've got to be very careful that we don't remove too much material because it's a clay bottom pond. It also means that it could have a thick layer of clay. Well, could actually it does have a thick layer of clay. Could be anywhere from 12 in to four or 5t deep. We don't know how much clay is on the bottom of this pond, but if we go through that clay layer, we could end up draining all of the pond into the groundwater basin below. So, what you're going to see Tim is doing is he's literally just using his bucket to feel for the hard bottom. He's trying to differentiate between the muck that's washed in and then the clay that's down below. So, he's using that bucket to feel his way down and in. at hitting the clay. He's going to start removing that extra material that's on top of it. Carefully skimming it out, but preserving the clay down below. Boy, that was a long explanation for that.
