i dont know if this is placed in the right place or not but ill try to explain whats been going on and maybe one of you guys will be able to help me out
my dad built a pond about 15 years ago that when filled is about 4.5 acres maybe 5 anyway it will fill if we have a rainy winter or spring but will quickly go back down to where it currently sits at about 2.5 acres, so we know the leak is around where it always goes down to. if it fills up it will quickly go back down then stay at about that for the rest of the year even through no rain, it holds good. what my question is do you guys know if theres any business who will try to fix leaking ponds? im in the southwest TN north ms area. btw the pond has great watershed and my dad for the first 8yrs said maybe itll settle and fill but its not going to fill we even have a well that we can run into it but it would cost a fortune to try to run the well all the time to keep it full. anyway im sorry if this is placed in the wrong spot ive just completely given up almost on the pond every living up to its potential and am willing to do pretty much anything. thank you for your time and help.

I'd talk to TJ here on the forum, and also possibly call Michael Grey (Gray Construction), he's listed in the Pond Boss Resource Guide as a pond builder in TN.

Sorry to hear about your leak issue - feel free to reach out I am happy to review your options and my time is always free to my Pond Boss family. I agree with Scott Michael is a great pond building pro, but rehab you're probably looking well into 5 figures - something to bear in mind. Reach out anytime: tj@hudlandmgmt.com

A buddy of mine had a similar situation south of Abilene Tx. He took a large pump and circulated drilling mud throughout the tank. It stopped the leak. No effect on the fish.

Curious, how long ago and is it still holding water?

15 years ago and it’s still holding water. Damn nice tank. He has a lot of them on his ranch. The cost was minimal. He owns a small oil company. We tried it just to see if it would work, and it did.

I have seen that work successfully many times and have done the same myself. However it will not work in every situation. If you have a leak through rough gravel (larger size) or through fractured rock it may not work without some dirt work.

thank you all for your replies i was thinking it would be an expensive project i need to save up a little while and then find someone who can do it i will save the info in this thread, because we spent alot of money building the pond and it would really be beautiful if it would stay full hell theres an island that isnt an island unless its full lol not to mention the great fish habitat that would be created if it were to fill. thank you guys
