I haven't seen any yet in my yard, but there are prairie dogs in just about every other yard in the neighborhood. They make tunnels everywhere. Is they burrowed up, couldn't they puncture the pond, leading all the water to drain into their home? Is that a danger for ponds? If so, how to protect against that?

The only thing I can think of that would protect the liner, if they do damage ponds, would be to put down hardware cloth below the liner.

Absolutly a concern they are like woodchucks and muskrats they can build elaborate tunnels . Like @addy1 said they have a few products one is concrete blankets its concrete infused on a fabric lay it down and leave it be and it hardens like concrete. then there are others who have installed chicken wire under the liners fabric. An other possibility is a asphalt and fiberglass product we use in roofing as a protection layer between the plywood and epdm if i remember correctly it was 10 bucks a 4x8 sheet. i know it wouldn't taste good to a ground hog but it's pretty tough and they may give up as it's not a natural product i have no idea if it would work or not

Do you know what the asphalt and fiberglass sheets are called? Are those flexible?

Yes flexible very similar to a sheet of paneling a little better then and three times as strong . but there are also others such as asphalic sheets are what i was refering to it's 1/8" or so

Types of commercial roof cover boards on the market include:


  • Cement – cementitious base with mesh reinforcement
  • High-Density Polyiso – compressed polyisocyanurate with a coated glass-mat facer
  • Perlite – volcanic materials combined with minerals, fibers, and cellulose binders
  • Asphaltic – a mixture of minerals and asphalt with a fiberglass facer

Where are you located? There are traps you can put out, or you can encourage their predators to hang out in your yard. My local area has ground hogs, but not many, and plenty of hawks.

In am in New Mexico. The praire dogs are very numerous. At certain times of the year, you can spot huge groups of them. There is an empty lot across the street just filled with their burrows.

Is there a generic name for what these are, when purchased for roofing? I can't seem to find any product, except roofing underlayment, and that seems quite thin.

Sounds like my property. Full of ground hog holes.

We have ground hogs, they tend to live under our building, garage, small shed, pole barn. I have seen them eating down by the pond but never a tunnel.

Weak ground exactly describes my back yard. When the sun comes out and there is no rain for a while, the ground is soft, with absolutely no rocks what-so-ever. It is a light powder all the way down 2 ft before I hit ground that is somewhat like clay. I will be covering the entire yard, that isn't pond, in rockscape, which I think would stop downward tunneling, but that won't stop a creature from tunneling from a neighboring yard and coming up accidentally through the pond, if that is something that they even do. I wonder if they have a sense of where water is, otherwise, they'd be coming up under lakes and creeks.

I don't believe they go deeper then a couple feet I could be wrong as I am not prairie dog expert but I do know in watching them and other such varmints is they often have a boulder over there opening. So rocking the entire yard may promote as much as deter. If I had to deal with them I'd do the concrete cloth for 3 feet and then chicken wire if I went deeper.

I can find huge pieces of chicken wire big enough to cover my area, won't chicken wire break the liner? Maybe I can put a layer of chicken wire down, then a tarp on top to protect the liner. Never heard of concrete cloth, Home Depot doesn't show that, it is a piece of concrete that is flexible?

The concrete cloth isn’t flexible once it sets up, but is literally a cloth embed with concrete. Depending on what your weather is like, you might be in an area with very little rain. I’ve got family near Roswell, I keep hearing about the lack of rain. I’ve got a thought for you if that’s the kind of weather you are dealing with. Since they like soft soil, make the soil under and around your pond hard. Till the soil in the pond hole till it is very fine, mix in cement powder, till it well till it’s an even mix, then mist it all down, a nice steady light misting until you’ve made the ground into cement. It will be hard on the ground hogs to get through that. If you get winter freezes, it may shift and crack, so add a good layer of sand and good underlying. Bonus points if you work hardware cloth or chicken wire into the concrete mix prior to it setting up, you’d have many years before they bother the underside of your pond.

You won't find concrete cloth at the depot it's strictly specialty stuff. You may want to pause on the build of your pond untill your positive what steps to do and when. Regardless of prairie dogs. Pond building 101 is to put down a layer of Non Woven needle punch fabric. This is to protect the liner from rocks, roots, trash you name it will it stop everything no . Some people use old carpeting. Some blankets I'm not that daring I used the best bang for my buck with the needle punch. In your case chicken wire then I'd put two layers of needle punch over the wire because it will rot eventualy so id a ll so get galvanized.to go all the way id put the wire protection board then a layer of fabric and then your liner . If rubber never sees the sun or scorching heat it can last for decades You have one chance at your foundation / start, if it fails your in for a ton of rework.

I have woodchucks in my yard with no issues at all to the pond. They eat some of my plants and walk in the stream but that is all. As always they are welcome and I will never trap them.
