You could use a tracer dye to see where the water enters the pond and where it exists.

This is basically a mill pond without a mill. It used to be very common practice, because water flowing out of a body of water has a more consistent flow for turning a waterwheel than water flowing through a natural stream or channel. I'm used to seeing them with a manmade stream in to fill it and another manmade stream out, which is where the mill and waterwheel would be. The stream into the pond is the mill stream, while the channel out is the mill race. I can't say I've ever seen it done with buried pipes like this, but in Europe and the northeastern United States, a lot of small ponds that we assume today are "natural" actually originated as mill ponds. Look on a map and there's a good chance there's a "Mill Road" or some similarly named street nearby.

That is pretty wild. Props to the neighbor for knowing about it and sharing info! Great job clearing that area and figuring some things out. Would like to see an update if you modify anything. 👍

Also suggest checking out old satellite imagery of your property if you haven't already (Google Earth Pro is free and has a nice simple historical imagery feature) to see if there are any images showing the pond or perhaps even the construction of it. Maybe you will get some little hints about the location of pipes or how it was used in the past. Excited to hear an update sometime soon!

The guy that designed that pond is very smart. Self leveling and just about maintenance free. Clean everything every spring and you should be good. You should be able to put fish in that pond as well.

Might be a good idea to document the drain locations(In and Out) and keep it with your land deed. That way the next guy won't be left confused if there is no friendly neighbor. Also if you put in a leaf grate you might want to make it an inch or so down into the pit so, one it keeps people from falling in, two installing it on the pit instead of the pipe at the bottom will give you more area to clog before it backs up, three it also makes cleaning by hand possible, four if it is and inch or 2 down the whole thing will be clogged before it overflows. If you go this route I'd make a strong grate for supporting weight then put a smaller gapped grate circle on top of it so that you can just lift it out and clean it with a hose. (Maybe with a handle.)

In a previous life I worked as a buried utility locator. I worked for a company that contracted to the power company the phone company the cable tv company etc. we also located private utilities, water, sewer, and drain pipes like the one that goes to your pond. I noticed that there was a wire attached to that clean out that you showed us. That is a locate point. You should really consider having it located and marked out for your records. I’m not sure how much they charge these days.

In hydraulic storm water design, the use of a clean out / breather has a few important features: (1) It helps you find the pipe location. This can’t be overstated. (2) As the name states, it is a point of clean out. We often use the access to jet and camera the pipe. The jetting is done with a high pressure hose to clean out debris and mud. If roots obstruct the drain, then a root cutter is used. Depending on the access, the pipe may have to be dug up. (3) This is also called a “breather.” The breather helps avoid hydraulic locks in the pipe. The breather helps the water to flow through the pipe more efficiently.

I think you owe your neighbor friend a dinner! Always fun Contant love your channel!

I would have loved to see the initial plan configuration of this design to how the installation process was achieved. What a kookie and clever design! 🐺🔧 Also, what a good neighbor to share that kind of information with you!

My favorite channel never disappoints, been following you since you had 20k subs. How the heck did you grow so fast? You inspired me to start my own channel during the pandemic. Just got monetized! Thanks for making great content.

That's impressive. The conduit with the string running through it and now this.. I wonder what other surprises you might come across. For someone so sofisticated, I'd be willing to bet he has schematics. Perhaps near a furnace room or even that remote building. Keep your eyes open for priceless antiques stashed like a buried vehicle or collectable war time artifacts.

I thought for sure this was going to be a collab with Post 10.

Could be designed as a trout pond, depth, clean, cool and fresh water.

Wow! That is really interesting! That took a little bit of ingenuity and determination to construct that pond.

Hope you update this, I'm curious about it all. I wish I had some advice, but I do not. Obviously the 'system' is designed to try and get hillside water to go directly to the pond somehow. Maybe when all this went in some of the trees were small, or not there at all, but I agree, putting that much pipe in a woods would be tough.

I've come across what I call pseudo springs. They look like springs but are not connected to an aquifer. They occur near hills that have an imperviable rock layer. Snow gathers higher up, melts and runs down through the soil until it hit the imperviable layer. It then follows that all the way down to the bottom of the hill and then bubbles to the surface. It looks like a spring but only lasts a few months (until the snow is all melted and bubbles away).

Oh, how wonderful! What a blessing! Great neighbor, too!

You could put a little florescent dye in the input and see where it comes into the pond...very interesting build.

One of my favorite fishing holes from my youth was dredged and turned into a gravity pond as a swimming hole for the neighborhood. It's amazing to see what appears to be still water not developing algae. It was a head scratcher at first until it was explained to me how that was possible.

Your pond is beautiful. We had a pond like that in PA. Fed by a little creek. Had to keep the intake clear. It was much closer to the creek though. Our pond had an outlet pipe that also needed to be kept clear.

Oh the joys of not just learning about an old house but also an old mountain property, lol. So cool!

That is so cool! Please keep us updated if you find out more information.

Wow. I was proud of myself for discovering some drainage quirks on my new property but this is on a whole other level. Fascinating stuff. How lucky to find you own something so unique. And glad you didn’t find a dead [whatever you were gonna say] in that hole!

Area looks really serene with all that flowing water and pond.

The mystery of Oak Island is solved 👌

I don't know why but I love this video.

It's like an in-ground ram pump. Cool. There are a ton of videos on Ram Pumps, I would suggest checking them out and seeing if they fit the mechanism you are experiencing. This is neat and I have to give a lot of credit to the previous owner.

What a nice suprize

This is the coolest thing ever. Thank you for posting this.

That’s a great pond, man. Awesome system. I wouldn’t change a thing. Just keep it flowing.

Thank you for sharing this video 🤍🙂

Wow very cool, props to whoever designed and made it!

Fascinating video.... That took dedication setting that pond up...

Wow! That's an incredible and unique setup.

@Silver Cymbal Considering that you previously found another fake rock, i suspect one, if not all, of the rocks in your pond are fake too and possibly contribute to the water control system. As you have an active drain with unknown suction, i would not swim in there. I would get a fishing camera (with lights built into the cam) and poke around on either: 1. a small boat or kayak with you in it 2. A small remote controlled model boat or otherwise primitive float dragged with a cable by you across the pond 3. a long lever balanced on a frame from shore, dunking and pivoting the system by hand. 4. Dangle it from a drone if you have one with that weight capacity. The fishing cam is a good sysnergy as you can do spot for such a cam on your channel like the other stuff on your channel. The tunneling over distance sounds like a crazy project but they probably did a slant drill with a thin bore over the distance, and then built the pipe into it by screwing sections of pipe into it to build it. Like how they do modern water wells, but diagonal. BTW, you need to get a grate asap on the drain area downhill as it is a hazard for anybody to fall in.

Absolutely amazing!! Thanks for sharing 👍🏻 greetings from Killyglen, County Antrim.

That was very interesting! Good luck with your pond.

You've got all of us hooked with this episode of mystery. Looking forward to your next submission about your pond. Very interesting... Sorry, wish I had advice for you.

This seems just a variation on a classic detention pond or retention pond. Storm water is collected and run underground to a pond. There is a discharge somewhere to keep it from overflowing. The clean out at the top is handy given the amount of debris entering the pipe. Thanks for sharing.

Very cool. Looking forward for more videos. Stocking fish and aquatic plant would be next after you figure out your ponds set up.

Beautiful property 👌 what a cool thing to have right in your yard.

Your are a Lucky man to have such great neighbours!

Your edit was awesome for this! I literally watched until the end and was entertained the whole time!

That's super cool. Well thought out the guy was a genius

I have no answer, but your property is amazing! I'm jealous.

That's crazy! Try something like an Atruim grate. They work better than flat grates in high debris areas. You'll have to clean it regularly but at least it shouldn't flood anything important if left for a while.

This was wicked cool. Thanks! Dave J

We have a similar size pond on our property but it's a natural one I believe. The water level took a big hit this year as it was very dry in the UK. Luckily the rain water soakaways from our house and neighbours properties feed into it. These are actually mentioned on the deeds about keeping them clear. It has filled up pretty quickly with the rainfall we had in the winter and autumn. Sadly the lower level killed quite a few of our ghost carp when the weather went very cold really quickly. The level is nearly back to normal now thankfully. I believe many many years ago they used to use ours for irrigation as there is the remains of an area used for pumping all that's left is a few brick walls. Very glad you managed to sort yours out. Great video.

The water flow from the capped white pipe you said was for clean out reminds me of the Ram Pump my father uses to fill his pond. Requires no power and could easily travel a couple thousand feet with the water flow you have.

Watching this reminded me of these ponds we have in the UK called Dew ponds (which are mostly fed by rain not dew). But are designed to keep the water cool to prevent evaporation, and stay that way even through droughts/mid summer and so dont dry up (in most cases). Normally they are built in places which dont retain surface water easily like Dorset to keep cattle watered. They think some of them could go back to the bronze age or further!

That’s a detention pond that slows the flow of storm water from entering the local streams too quickly. It’s helps to stop flooding and the release of contaminate from entering the local streams. I have one in my neighborhood as well.

Awesome content as always. You can get crystal clear water for viewing if you establish a push through on the levy to the creek below (assuming there’s a downhill portion to the pond levy..so you have constant water flow in and out. Then you can control the speed at which it flows to produce your hydro. Hope that makes sense

There is channel of some city worker who just posts him working unclogging various drains. I think its called post10. He comes across very unique systems, and show how drains really work. He usually finds a clog off the side or somethere else to allow flow.

Amazing! I have a pond that was supposedly fed by an underground spring. The water level had risen and lowered naturally with the seasons. I thought it was odd that "all of a sudden" the water is lowering and no longer rising. Who knows, maybe this sort of thing was more common than we thought... thank you for sharing. I will be searching the property for pipes and drain equipment!

Great story. I love a good pond.

That is really cool! I would try and do some micro hydro power stuff!

What a cool thing to discover on your property.. like finding a hidden room sorta..

We have a pond on our property, about twice the size of yours, and it also has a drain, but the drain is only there to keep the pond from overflowing in case of heavy rains (we live in a hurricane zone) The drain is pretty much stopped up, and so during periods of super heavy rainfall, it does back up into the lower portions of our property, and sometimes takes several days or a week for the pond to return to it's normal banks. The drain in our pond is near the top level of our pond, and is designed to empty into a drainage ditch, which is only about 50 ft from the edge of the pond. If you look on the edge of your pond nearest to the direction of where you think the water may be flowing, you might find it, of course searching during times when your pond is at it's lowest. Our drain is covered by a metal grate that can be raised and lowered, but the pond has been there for so long that my husband thinks leaves and debris have partially clogged the drainage pipe. The dye in the water suggestion might work to help you find the drainage point. All of this aside, none of this has affected the wildlife in our pond. Our pond is teeming with fish and turtles, but as I already said, the drain is near the surface of the pond, so during dry periods, the pond only drains to a certain point, and does not continue to drain once it reaches the level of the drain.

That's just amazing . I have never seen any such kind of a system .

COOL! It's not a mosquito farm.

Since you like solar why not try hydro as well since you have a pond

That was absolutely wild,gravitational pull is in constant motion everywhere,as above so below…

That is the coolest thing ever! Love your videos, man.

That pond would be an excellent place to populate with trout for your enjoyment to fish and enjoy your property.

That's awesome. Your neighbor must have witnessed the construction knowing where to guide you

Really liking this new format relating to your land. Also, great video!

Lol I love seeing my favorite KZfaqrs watching other great KZfaqrs! The Bama Bass pond is awesome

My buddy in Pa has the same kind of setup a natural sump well fills a 2.5 acre pond through a pvc pipe under his front lawn. On the back side there is an overflow pipe to keep the pond level that empties into a stream.

Great video. An ingenious system.

What an awesome neighbor!

There’s another channel here on KZfaq called Apple Drain’s. I think they’re down in Florida. The guy is constantly posting new videos about everything drainage. I bet he would have some answers for you. For some reason unknown water sources creep me out😳😂

That's an awesome system you've got, with a bit of regular maintenance your pond could be 10 times the size it is now. For help, businesses that work on septic systems also work on water supply or pond systems. Most of this you can do yourself once you know the entire system. If I were you, I'd be digging out a larger pond and eventually connecting the 2 together. You're sitting on a gold mine of a resource, don't waste it ... expand it!!!

Minus not having a grate that’s a well thought out and awesome pond! Beautiful land as well. Time to stock it! Bama Bass channel is an awesome series as well!

Nice video! I think most healthy ponds happen when they have an inlet and an outlet. Getting the pipe thru the property is only slightly difficult with a tool called a “Ditch Witch.” It’s like a giant slow motion chain saw for the ground. Plus you only need a 2% pitch to get water moving. The thing I would do, is try to create a cover for wheee you were digging. That would slow the accumulation of leaves and debris. HTH.

Wow, hell of a thing for your neighbor to know, props to them for bringing it up.

I’m just jealous. Awesome set up.

Can’t wait to watch along and see how it all goes 😁

Epic. Keep up the great vids.

Your new property is pretty amazing

I rarely comment but that is so impressive, I’m guessing a lot was done by hand! Hard workers back in the day..

Old timers were ingenious and could do amazing things with HARD work, little money and supplies they could usually scavenge.

There's no need to pitch the pipe. As long as it stays below the level of the source, the pipe could go down a mile, doesn't matter because water finds its level. In other words, even if the pipe goes below the level of the water in the pond, it will rise back up to come out the outlet in the pond

Looks like really nice property!

That's a ~very~ cool pond. [smile] You're a lucky guy. [grin]

Stock it with Bass !! Lol it's a neat system, yes a leaf grate would help and keeping it clean is always good, get some Ducks , You're Blessed !!

that was fun, watching you discover how it works as it happens

My only advice is to get the skates sharpened for winter.

if you're still encountering issues locating the drain outlet on the pond side you may want to try using dye to locate it. I only recommend the dye because of the distance from the source. Also you should absolutely put a screen on the source end of the drain at that culvert.

I'd use a non toxic dye at the drain next to your driveway and see where it comes out. It should float to the surface after entering the pond so you'll have some idea where it's actually at. I'd also definitely cover that access with a screen of some kind too and check it every couple weeks in the fall just to make sure it's not too heavily covered.

Great video. I subscribed and look forward to an update on the mystery that is your pond.

Hi their put some dye in the feed water. Great Video, Regards Richard 🇬🇧

What an adventure this place has been!

That is really weird. But kinda cool being fresh water all the time! Good swimming spot on a hot day.

Wish I had a pond like that ! You are so lucky ! Peace

Looking forward to seeing the follow up video

As a landscaper who lays a drystream bed stone by stone this amazes me. That someone would go all the way to do that. Make a truely unique pond!

Pretty cool stuff!! 😊👍

@silvercymbal here is a suggestion to make cleanout easier and keep your inlet from plugging. I have a civil engineering degree and spent a lot of time in my adult life messing with water flowing over and underground. On your inlet pipe, put a 90 degree T and add about 18" of pipe pointed straight up. Then put your leaf screen on top of that pipe. The bottom part of the T should have a cap that you can easily remove or even a valve controlling water into it. When you do not have water flowing and you want to drain any leftover water out of the pool by the inlet pipe, open then bottom leg of the T for full drain and inlet cleanout.
