We purchased a 20 acres property that has an existing pond on it. Dam however is completely washed out. I'm talking a 10 foot wide gap about 20 foot deep.



Well what's left is about a .5 acre pond being creek fed and it runs out the dam. Well after 4 hours of weedeating around the portion that should be underwater. I made my way down to the water.





Got broke off twice, there's some bigger fish in there. Haven't seen any bream, guess they are on the frog and lizard diet which there isn't a shortage of.

Gonna pick up some fish food and keep them healthy to have some fun with them until we can get the 80k we were quoted to fix the dam.

It ain't much but I'm pumped!

Feel pretty confident you got plenty of bream in there if you have bass

You'll have a hard time trying to get adult bass to eat fish food unless they've been trained on it as fingerlings.

I'd be out there with a rented bobcat digging shite up and dumping it in that crevice myself. Not saying that's the right way to handle it, just saying that's what I'd be doing.

It's in my plans haha. The issue is the dam has a rock face going through it. Water catches a seam and there it goes. Looking at Google Earth history, they've dumped dirt in it twice and it's failed.

ETA: one quote was 70k, one was 80k. The 80k said they could build a new dam in front of the old one for 50k. Making the pond even smaller. It should be close to an acre when full. I want it at least an acre, hopefully 2.

Probably needs a spillway in or beside the dam. Water over topping a dam will cut it out with quickness. I’m sure if they are giving you a quotation of $80,000 for the fix they are probably going to completely remove the dam and re core it. Needs a clay based core that extends below the bottom of the lake.

Really needs a stand pipe spillway with a gate valve in the bottom. Emergency spillway at the dam to allow floodwater to get out fast enough. All dependent on the watershed above lake.

Quote still sounds high though. How long is the dam?

Maybe 150 feet. It's also too high and the slope into the pond is too steep. I'm having trouble even finding someone that wants to fool with it.

It had an emergency spillway, no drain pipe.

High Cotton, would you mind chiming in with your expertise on my other topic here "36 inch culvert?"

Research seepage pipes. Our dam has some, it's because all earthen dams leak some, so you get some of that seepage directed out. Something like some PVC pipes with bunches of holes drilled in them to collect seepage, but you can't bury them in just dirt, think french drain where they are encased in some gravel, then dirt packed around that. And sloped. Might buy you time in between dam failures.

Whatever you do, do not contact the government for help.

Water would cut between the concrete and soil transition.

Yep, has to be clean rock free clay for the key way/core trench. That's why the quotes are so high.

That will not fix the problem.
It will just wash out on either side of the patch job.

That's probably about right. They will have to remove the whole dam and cut a new keyway, then create a new core with good clay. Which if they are trucking in, is not cheap at all.

One quote had them bringing in 1400 yards of clay, knocking down the dam a bit, removing all the rock, then recoring it.

Another said there is enough clay on the property. There is, it's just full of rock. Not sure what their plan was.

I plan on spending the winter tearing out what rock I can, cleaning it up from weeds and such. Building a bridge over the creek so I can get equipment back there.

Don't have any heavy equipment, but kinda seeing what I can do to get ready while I wait out prices dropping. Hoping this economy bombs honestly (selfishly it benefits me) then our house will be cheaper to build, and pond cheaper to repair.
