[@geoffburnham3967]

To measure your evaporation just place a bucket in the pond fixed so it won't tip over and fill it with water. Evaporation from the bucket will be the same as the rest of the pond. You can easily see how much water you are losing to evaporation. The difference is leakage. Good luck with fixing it.

[@JosephHolecek]

I was told always install a rubber roof membrane to line stock ponds from a guy who builds them because your issue isn't uncommon people say install heavy clay to line it he told me it filter out of the pond

[@diggingkentucky8620]

I'm in the excavation business and remember watching this pond being built and saying to myself that won't hold water. I would suggest bringing in good clay and lining it at least 18" deep and packing it in with a sheepsfoot/padfoot.

[@cacaokingdom3122]

A rip rap channel to concentrate water coming in that minimizes erosion would also be a solid idea. The fact that the shale layer is fully exposed in some areas means that bottom is full of holes. The water level is settling down where the leaks stop.

[@arlingtonguy54]

My pond is the same. I built it on a wet spot (spring) so when water table drops the pond water just flows down into the water table. My last resort idea is to line it with clay. I was hoping 6” thick but you are probably right about the thickness and compaction.

[@tacticalultimatum]

We got a quote done for clay for us. It was 225k and 80 trucks full for a 3/4-1 acre pond

[@sfunk1068]

Might be cheaper to put a rubber liner in. We do ponds for irrigation requirements that are lined. A pond that size would cost about 200k.

[@sfunk1068]

Another cheaper fix would be add bentonite. Install Heavy, rottatill it in and compact it.

[@definededser]

Hi the property we bought had a dam the previous owner had not been able to seal, found a product called " Damit " it's a water crystal powder just sprinkle over the dam the crystal are drawn into the leak as it absorbs water they swell plunging the leak and the dirt sediment becomes combined with the slime sealing the leak. As water level rises just sprinkle more around edges to fix any other leaks that may be present. I waited till a storm filled the dam then did the treatment within 3 days the water was now holding. Highly recommend this product, heaps easy compared to clay lining. Cheers

[@jgsinc1079]

I’m in the excavation business myself and I’ve fixed quite a few leaking ponds here in eastern Ky. I would suggest atleast a 12” cap of clay, rolled with a sheep’s foot, a layer of Betonite mixed in with another layer of clay on top of the first 12” cap at around the same depth as well. This will seal it off and prevent it from leaking in the future.

[@haroldphipps3457]

PLEASE listen to this guy. Or Dirt Perfect Or Let's Dig 18 Quit guessing!! It isn't going to fix itself. It isn't going to silt in. Good call on waiting till spring!! But if you aren't going to take this posters advice, or DP, or LD18, just get a bulldozer and make it a flat spot.

The french drain is amazing. I never would have guessed that much water would flow through it.

[@SpicerDesignsLLC]

Wow that french drain is working amazing.

[@treyt7651]

I own a pond business and have delt with this problem on a few ponds in my area. typically we will go around on the owners property and locate a decent source of clay that we can haul over to the pond and will go about lining it with a foot to 2' of clay over every surface. Usually we also turn the borrow area into a pond as well. Significantly cheaper than hauling it in since trucking costs are so expensive these days.

[@jasonwhittemore3083]

opening scene was awesome.

[@Johnthelittlebuilder]

Just a little thing to do before winter and spring.. I had similar issues with my pond after a drought- I pile my snow from the driveway and parking area on/in the pond area- definitely helps in spring to fill up

[@JCWren]

I wonder if you set out a wide, shallow pan (like 2 or 3 feet diameter), filled it with pond water, put in a ruler, you could get a rough idea of evaporation. I'd make sure the water was close to the top so you're not shielding the water from any wind, etc. Set it somewhere in the pond basin so it's exposed to the same wind conditions, etc. Use a pan that doesn't have a hole in the bottom so you're not simulating the pond :)

[@goodness-mercy]

I'm so happy about how the "French Drain" is working. Based on my experiences (that I have already shared with you) when the rain became more consistent, the quantity of water that will flow days after the rain will increase exponentially! (You might consider some rocks at the end of the flow for prevention of erosion into the pond of your sand.) You will notice the water will carry less sand as the "System" cleans itself.

Bummer Adam. Lots of water flowing out of that pipe...but it sure does seem like you have a permeable bottom in the pond somewhere. I have been a part of lining a pond with bentonite. It took 20,000+ pounds. Tilled into the bottom. I am sure there is information out there that explains application.... Good luck and thanks for sharing the update!

[@craigwilson9560]

Adam, thank you for the update. Dad and i installed a lot of French drains. It will help out a lot. So sorry you are having problems. We used Clay and Bentonite and put pigs in there and let them root and it sealed the pond. We always tried to do work on ponds in fall winter. Usually, in winter and spring you tend to get more rain at least in our area. Have you secured a bucket of water full and check 12 and 24 hour for evaporation. Each day. That would give you a good idea on how much your pond should be evaporating the water. We also repaired leaky ponds with muskrat holes. There we had to dig down find the hole and repair it all the way through the dam and repack clay with Bentonite. Hope you get it solved and sorry you are having so many problems Adam!

[@yesli...879]

I dont know anything about ponds but seen several videos of people having or making ponds and your pond is naturally blue 💙

[@ronaldlee2376]

Upon having serious droughts in past, i have installed wooden snow drift fence on west side of my pond. 10" dry snow equals 1 " of water. As snow melts, water enters pond. We have more than 30 ponds within a 2 mile radius, they seal & fill at their own rate.

[@Andluth]

With all of the sediment coming out of the french drain, if you directed it to the center/bottom of the pond it might give you a headstart on plugging the "hole"

[@SomethingAbstract]

The "hole" isn't in the middle its the whole pond not enough clay to seal the bottom no liner is gonna leak

[@S_and_S_Farms]

Who doesn’t love pond videos? 🤔 We all love more pond videos! 😎👍

[@josephmascia401]

Don't be surprised, after lining with clay, if you continue to lose water through the bottom once you go through another high groundwater season. The high groundwater pressure can reestablish your leaks. "Ponds are tricky," the old excavation guys would say. Good luck with it. Very interesting content!

[@grantbrittain2774]

As digging in Kentucky I too have been in the excavation business for 30 + years.. and I agree with him about adding 18 inches of clay as a liner.. also when we do holding cells for water treatment plants and sewer treatment plants we spread bentonite clay on the clay liner. Disc it or till it in the first 6 inches of the clay liner then sheepsfoot it in.. it's costly but will not leak..

[@michaelfarinola5044]

Our pond was down 5-6 feet most of the summer, normal leaks and evaporation. It rained a few weeks ago and it is all topped off the last three weeks, but we also have two springs that form two separate small creeks that feed it. Considering that I would look at adding more feeds if possible. Best of luck with yours, you will get there.

[@addictiveaussie]

Two things when building an earth dam that are a MUST. 1 the base across the entire dam needs to be ripped to a minimum of 800mm (30") and all rock, and sandy or gravel sections removed and 2 the whole area then needs to be compacted in 150mm(6") layers using a sheep foot in a 8-way cross pattern.

[@farmerkevin]

At least 25% of the ponds i see in my travels have issues. Clay is almost always the cure, good luck with yours.

[@chalkao5071]

Beautiful work! Have you considered resurfacing the ground layer with thick plastic liner? There are plenty of pond liners out there. Working with nature is fun. You can track not only water loss to evaporation and ground absorption, but also the rate at which both of these are taking away your water. All you need is volume of first fill, wide bucket deep in the middle of pond filled with water (isolated from pond water in a bucket), and record the time over which the volume in the bucket and the pond have gone down. I know a bit of numbers involved, but your original fill is equal to the total sum of your current available pond volume, volume lost to evaporation and volume lost to ground absorption/leaking. Good luck.

[@jefftempest9222]

Been there, done that. I believe a liner is your best bet. I dug a 1/2 acre pond 12 feet deep and hit a limestone formation. Water ran out as fast as it ran in. After trying every repair method, including digging a second pond to use the clay to line the first pond I decided to buy a liner. You have done so much work and have a great flow now if you used a liner you would have the pond you're looking for. It's cleaner and provides you with no absorption.

I'm in SW Ontario almost straight across Lake Erie from where you are. We also had a dry summer. I have ponds and a wetland on my property and they are the lowest they have ever been this year and that's with no known leaks. When the wetland was first dug 12 years ago we did have a leak. It would not hold water for anything. I finally found it and it turned out to be an old clay field tile that didn't get completely plugged up when they dug it. Once it was dug up and packed back in with clay, no more leak. It sure doesn't take much to have your water level drop. It goes down a lot faster than it goes up. Good luck with your quest to find your leak. Hopefully it's something simple like mine was and you get it fixed up in the spring. Dave

Might be cheaper to have a well installed to keep it full but your plan of clay is a solid one, I think you would need around 2ft of it though, 6-8 is not going to seal it. Then you will have to dig out dirt to replace with clay.

[@florianhuber262]

Austrian Permaculture pioneer Sepp Holzer has built a lot of ponds, including some high up on mountainsslopes. According to him, A) you can get ponds to be "tight" with pretty much any soil other than sheer sand, and B), complete tightness is actually not desirable. Natural ponds have varying water levels, and water being drawn into the surrounding earth increases fertility there, one of the main reasons he builds ponds in the first place. But, assuming you want yours primarily for the water/aesthetics, he would probably do several things. Firstly, dig down deep enough to find a watertight layer (say, sheer clay), even if that means digging a deep trench first where your dam/levee is going to be. Then build up the dam on top of that from only very fine material, i.e., separate fine and coarse first (he let's the excavator drop the material onto heaps from a height, so bigger stones/pebbles "roll away". Make sure there's no organic material in the dam (you did that anyway, it seems). The most interesting technique, I think, he took from his pigs. They are able to make a mudbath for themselves in pretty much any soil. The way they do it is by digging their snouts into the soil when it's WET, basically kneading the soil. He uses that to seal the soles of his ponds, by filling in a few feet of water, and letting the heavy excavator in to knead. For that he uses a longish, narrow excavator bucket which is rammed down into the mud in a back and forth movement (many times, obviously). Just imagine how a pig would do it, basically. He never uses pond liners, let alone concrete, because it makes the water go stale and dead, and separates it from surrounding soil, which is not at all what it's supposed to be for fertility. There's quite a few videos on him and his approach, in English...

[@hoyks1]

I'm not from around there, but the water in the pond looks unnaturally clear. Did you add dye/clarifier to the water? If you stir it all up and get the water nice and muddy, then the clay can settle and plug the leaks on its own as it settles out. Once the dam is holding water, then worry about it looking nice. An established dam will settle out and clean its self over time, if you keep the livestock out of it. A friend had a leaking dam, so they let the water get to about 1' deep, then let his kids and mates cut loose in it on their trail bikes and 4 wheelers. Chewed up the bottom, spread mud everywhere and the dam sealed next time it rained. Another guy I knew swore by gelignite. He'd throw a few charges in, stir everything up and the concussion would also compact the layers of soil under the water

Clay in my area is not a reasonalble option, but a very good idea if you have it local. It's been 3yrs, 3 excavationsa and two contractors later, I'm still chasing a solution to the probem. If I started over, I'd bury an EPDM liner and call it done. I've also used 1.5 tons of polymer sealent (enought to seal 1 acre) that is referred to in the comments, and quitely frankly not a fan of the solution.

[@stevestormssr5492]

The French drain is working great, but, I see a lot of dirt washing into the pond from the ditch. I think your best bet, would be to dig out about 3 feet all around and as you said, fill it back with clay! Q. Ditch your siphon pick up volume with the heavier creek flow?

Plant some trees arround the pond to shade it and prevent evaporation, that also will stabilize the edges and prevent leakings by absorbing part of the water
