Hi! Couple years ago I bought a house with a nice bit of property in Westchester County, NY, including two ponds (I think about 0.5 acre each). The lower pond has a stone dam - it looks like a dry stack stone wall with a sluice gate in the middle.

Over the last 8 months or so, we’ve at 4 or 5 storms that have send the water level soaring, and water is pouring over and through the dam (not just through the sluice). I am now seeing some of the rocks bulging out where water is pouring through and am concerned that the dam will soon burst.

I’ve been googling in search of a company that can repair the dam but I can’t find anyone. Stone masons I’ve found don’t seem to do water, and pond construction companies I’ve found don’t seem to do stone. Any suggestions?

Thanks!
