Introduction: Backyard Pond and Waterfall: No Experience Necessary!

Picture of Backyard Pond and Waterfall: No Experience Necessary!

I have wanted a pond my entire life. When I was seven I begged my mom to let me build one. and kept begging for the next nine years. When I turned sixteen, she finally said yes.

Five minutes later I was in the backyard with a shovel.

It took a few months to complete, though I only worked on weekends, and totaled around $2000. I had no experience, and was only going on the advice of the guy at my local pond store. It was a lot of work, but the result is beautiful. My mothers trepidation at the project was unnecessary; she loves it.

The point being, you do not need any fancy tools or experience in the concrete industry to make your backyard a paradise. If you have the time and the money, trust me, it's worth it. Your backyard should be a place where you can relax and unwind, and there is nothing more relaxing than the soothing sound of running water.

Step 1: Planning

Picture of Planning

Do your research first. The internet has a wealth of information, but an actual person with experience will be invaluable to you. Find a local pond store and pester them with every question you can think of. I'm not joking, ask them about absolutely everything. If they can't answer a lot of questions, find someone who can.

Now find a space in your yard. It is preferable to build it on a hill, but anywhere that looks pleasant should do, as you will see in the next step. It also helps to go see other ponds that have already been built.

Draw pictures of how you want it to look and show them to your pond supplier. It might also help to take a picture of the area and print it out, then you can draw directly on it.

I chose this area because is easy to see from the house and looks gorgeous underneath that tall Japanese maple.

Step 2: Digging

Picture of Digging

First dig the outline of your pond so you can see how big it will be. Pile all of the dirt where your waterfall will go as this will be how you will sculpt the contour of the falls. This is especially important if you are building it on flat ground, as it will give you the height you need for the falls. You may not need all the dirt, especially if you are on a steep hill like mine.

How big you want the pond depends on aesthetics, but also think about what you want in the pond. Koi need a LOT of surface area and it is best to have it at least 3 feet deep to prevent them getting eaten by birds. Goldfish are much smaller, and can stand a smaller pond. My pond ended up being about 9 feet wide by 4 feet and 3 feet deep. You might also want a shallower shelf around the perimeter of the pond to put potted plans on. Also be sure to slope the sides slightly so that it is easier when you put in the rocks later.

If you are make a deeper pond, dig the sides in steps so that each wall is shorter, and therefore more stable. The walls on the deep end of my pond are about 3 feet, but that really is a bit tall (I didn't have the room for more steps). Aim for the sides to step in segments of less than 3 feet.

Step 3: Sculpt!

Picture of Sculpt!

We will be covering the dirt in a sheet of rubber liner and then stacking rocks on top of it, so first we need a general outline of how the water should move. I put in three small reservoirs with tall falls spilling into each, one after the other. Again, check out lots of pictures online to get inspiration for how you want your falls to look.

Make extra sure the walls of the falls are high enough. Mine weren't quite high enough so I had to glue a lot of rocks around the perimeter of the pools to keep it from spilling over.

Also keep in mind that the bigger the falls, the bigger the pump you need to buy. Your pond supplier will be able to tell you more, but my pump is 6600 gallons per hour and it was $600, the most expensive part of this project.

Step 4: Rubber and Rock

Picture of Rubber and Rock

Go back to the pond store and pick up some rubber liner for your pond and waterfall. Measure the approximate surface area of your pond and then get a lot of extra liner. Too much is better than too little. Then simply drape the sheet over the contour of the dirt. As you can see in the second picture, I used a separate piece for my pond and my waterfall.

Ask your pond supplier where there are good places to get rock. Mine directed me to a lovely quarry where we got 3 tons of basalt stones. You want a mix of large and small and of different shapes. You shouldn't need any glue yet. Find rocks that fit together somewhat snugly and they should stack up nicely.

Step 5: Skimmer

Picture of Skimmer

You may want to also consider a skimmer, especially if you are building a larger pond. The have filters that take in debris and make cleaning a bit easier. Though skimmers are expensive, so talk about it with your pond supplier.

It is at this point that I apologize that I did not take pictures of the skimmer being installed. So I will attempt to describe it using pictures of it already installed.

The skimmer goes in a separate hole dug next to the pond so that the skimmer intake is right along the edge of the pond. There is a line on the front plate of the skimmer. This is where the water level should be. Dig the hole to the correct depth so that the intake is positioned at the right height for the water level to be where you want it. It is very important that the skimmer sits level in the hole. Make sure that the soil underneath is very compact and level. It might also be a good idea to put gravel and sand at the bottom so that you can get the skimmer perfectly level.

Once you have your skimmer in the position you want, you need to attach the liner. The faceplate of the skimmer comes off. The liner is screwed in tightly between the faceplate and the rest of the skimmer (see pic 5). The faceplate doubles as a gasket which seals the skimmer so that water can't leak between the skimmer and the liner. make sure that there are no folds in the liner around the faceplate as this will disrupt the seal and it will leak.

Once the faceplate is screwed in over the liner you will cut out the square of liner that is now covering the intake.

Lastly, cover everything up. As you can see in the sixth picture, I used a large piece of slate to cover the main body of the skimmer and smaller rocks around it and in front of the intake. It still shows in a couple places, but no one really looks close enough for it to matter. I even know its there, and I hardly ever see it because your eye is drawn to the rocks rather than the plastic.

Step 6: Keep Stacking! Your Almost There!

Picture of Keep Stacking! Your Almost There!

This is the part where you finally need glue. You'll need to seal around your spillover rock to keep water from just going under it. As you can see in the second picture, I used flat pieces of slate at the top of each waterfall. Use a foaming waterfall sealant like the one in the picture to glue and seal any rocks that you need to. As I said before, my walls weren't high enough so I glued rocks on either side of each spillover rock to keep the water on the right path.

(Pro tip: use rubber gloves when gluing. That foam is sticky and will stay on you hands for weeks and your clothes will be ruined forever, so don't wear your Sunday best)

As for everywhere else, just keep throwing rocks on until all of the liner is covered. I used small river rocks to fill in small crevices between larger rocks. I also covered the bottom in river rock.

Again, sorry for the lack of pictures. I did this three years ago.

Step 7: The Pump

Picture of The Pump

The pump assembly is pretty simple. Pump attaches to pipe. Pipe takes water to top. You'll need to glue the pipe into the outlet on the pump, and maybe splice in a ball valve if you feel inclined to turn down the flow a bit, but this really isn't rocket science.

How you assemble your pump depends on what pump you have, if you're using a skimmer, and what other attachment you might want, so I won't go into detail on it. Again, talking with someone who has experience is your best option when deciding how to layout your pump.

Step 8: Fill 'er Up!

Picture of Fill 'er Up!

You might want to test the falls with your hose once, but after that you're done. Fill it up and fire up the pump. Add plants and rocks in and around the pond and enjoy your beautiful piece of nature!

Step 9: Final Notes

Picture of Final Notes

I have very hard clay where I live. This made it hard to dig, but it also means that the end product is very stable. If you have softer soil where you live you may want to add sand and compact it very well so that things don't sink when you add the rocks and water. Using larger, flatter rocks will also help.

Something else to think about is shelter for your fish. You can see in the picture that I used a piece of slate and a rock to create a hiding place for my fish. Before I did that there were herons coming to my yard and eating my fish!

Above all, trust yourself. You will make mistakes, but they won't ruin the project. Use your ingenuity, it won't fail you.


NathanSellers (author)2015-04-25

Great job on this. I helped my dad do this when I was about your age and it was a blast. Your design is great! Way to be ambitious and figure it out. My dad and I used concrete to keep it all together. How well does yours stay together?

I helped my,dad do this when I was young too. I had to double check you weren't me. haha

I've never had a wall collapse. Sometimes the rocks around the edge get kicked into the pond, but that's really easy to fix. It's been running for almost 3 years now without any significant problems.

DnBrmg89 (author)DragonTamer4582015-04-26

I've made these before and yours is the closest to the correct way I've seen. I'd just suggest that you avoid the smaller rocks for a few reasons. you will likely need to redo it in a couple years depending on the soil you have or sometimes just luck, so small rocks make it tedious to take apart. Also you want larger flat rocks about an inch or so thick for support of your walls with no cement needed. Start by lining your walls with the rocks then do the bottoms. if your aiming for deeper pools do it steps so your walls will be more stable. Otherwise you did good. And a good trick to help spare your fish from predators and make them more comfortable in general, build somewhat of a rock table at the bottom that they can hide under.

DragonTamer458 (author)DnBrmg892015-04-26

Oh, I forgot to show the rock table! That's what the planter in the pictures is sitting on. And like I said, this has been running for three years without any problems. I did remodel the waterfall, but that was for me. There was nothing wrong with it. Although I do agree, larger rocks would make it easier. It's also on top of very hard clay, which is probably why nothing has shifted very much. I'll add something about that too.

Thanks for your comment. I appreciate it.

Okay, updated it a bit. If there's anything else I left out, let me know.

AmyLuthien (author)2015-04-28

I really like how you managed the waterfall, how it "disappears into the woods" like that. So many times I see people making waterfalls by heaping up an unnatural-looking pile of stones at the head of their pond, and that just doesn't make any sense.

Thanks. Those trees have been there for 30 years and I thought that it would make the perfect look with the canopy stretching over the pond. The whole disappearing into the woods thing was kind of unintended actually, but I'm really happy with it.

You should be happy with it, you did a fantastic job!

lfoss (author)2015-04-28

Wow!! Absolutely beautiful!! Can you come build that in my yard?? =P

DragonTamer458 (author)lfoss2015-04-28

I can and will, for $30,000.

RobinT6 made it! (author)2015-09-06

$2000? That's crazy. I've built two ponds in two of my gardens and never spent more than the cost of the rubber lining. You can regularly find rigid pond liners for free or cheap on Kijiji and rocks can be had for the taking from any river.

The large pond on the left had a rubber lining and was the first I built, with no experience. The second pond used a rigid pond form that I got for free and had a small stream and waterfall. I purchased the water lilies, but the rushes were harvested from a roadside ditch. Both ponds had fish that overwintered (a challenge in Calgary, Alberta.)

*sorry for the quality of the pics — they're old and digital cameras weren't as good then.

DragonTamer458 (author)RobinT62016-09-13

Good point, but realize that this is a rather large pond with a skimmer and a 6500gph pump. Those are a few hundred dollars each where I live. It doesn't look like there's a pump in any of those pictures. Two large sheets of liner for this size pond isn't cheap either. Yes, you could probably build one cheaper, but I had the money to put into it and I got a good finished product, so I'm pleased with it.

leserrou (author)DragonTamer4582017-05-29

And you should be (pleased) because you did a great job. It is beautiful and well done for a first!

dollywild (author)RobinT62016-04-26

In the US its illegal to harvest or remove anything from public land. So unless you have a friend with a huge property and a river, you have to buy mundane things like rock and plants. The fine, plus putting it all back, is just not worth it.

RobinT6 (author)dollywild2016-04-26

who purchases rocks? I don't know where you live but here in Alberta there is a large pile of stones in almost every farmer's field and they are more than happy to give you all you can load in the car. Or, you can find all you want for free simply by advertising in kijiji or Craig's list, if it comes to that. As for plants, the photos you show would cost about $50 for the water plants if purchased at a greenhouse. A water lily costs between $19.99 and $29.99. You can certainly harvest rushes simply by asking a property owner with a slough, or that roadside ditch, for permission. That's how I got the bull rushes I'll be putting in my pond next week.

you built a gorgeous pond but people should know that it doesn't have to cost $2000. In this economy, few of us have that kind of money to spend.

wmistler made it! (author)2016-04-26

NEVER build under fir trees. I tried to buy an hour of a pond guy's time for advice but he put me off for a couple of weeks. I soldiered on in my ignorance. It was beautiful but no filter was big enough. After about five years I accidentally killed all my fish and made the wise choice to tear it all out. It all started when I dug a tree stump out and I had a big hole...

I tore it all out last spring and started some lawn. I'll rebuild the fountain again because the reinforced concrete dog tunnel substructure won't be easily demolished. I'll use a plastic holding tank to make fir needle cleanup easier.

TUSHARKHANVILKAR (author)2016-03-13

i would make one like that

lucianoabcd (author)2016-03-04

Very nice work. The best, I think, is how it seems to naturally come out from the "little forest" in the back.

Just Like You (author)2015-11-08

the commentary you wrote in prior to getting into of the steps is great and encouraging. Thats great to see that! Also I really love you blended it all in with the natural landscape! I could go on and on with compliments and questions but I'll save us all the time, & leave it on you done some great work man. cheers

Just Like You (author)2015-11-08

its BEAUTIFUL & an exquisite well-crafted piece of work !!! You've got the gift of not only the "know-how" but you've also got the eye for design !!! KEEP UP THE GREAT WORK & future instructables I can't wait.(You're mom's gotta be proud & I bet it's safe to say that your project's definately talk of the block for sure). Gr8 work

bilski (author)2015-04-28

That looks great! I have a pond I inherited when I bought my house that I've partially rebuilt and I can tell you a little bit of planning and forethought goes a long way!

Something you may want to include are notes about dechlorinating your water before adding fish, and keeping an eye on algae levels.

RobinT6 (author)bilski2015-09-08

no need to dechlorinate the water chemically. Just the new pond sit for a few days before adding fish. As for topping up the pond, we just use the hose.

DragonTamer458 (author)bilski2015-04-28

That wasn't really my intention for this instructable, I really just wanted to show how to build it. I may put up another on the maintenance required to keep it looking good.

DeniseR4 (author)2015-05-26

Hello there,

My son and I are looking to do a pond/waterfalls in our yard which lends itself very well as there is a nice slope. My one concern about the location is the trees that are around it. While it makes for a more naturalized setting, will the tree "debris" be a problem? By the way, your pond is very beautiful! Your mom must still be absolutely delighted. I think my son will do a great job, too!

Thank you,


DragonTamer458 (author)DeniseR42015-05-31

Debris can be a bit of a problem. A skimmer helps, but I still cover my pond during the fall to keep most of the leaves out. So for a couple months it really isn't attractive, and I've found that even with the cover I still end up having to scoop out leaves. It's not hard work though, it just requires some routine maintenance, and personally I think it's worth it because it makes a striking look in the springtime.

Post pics when you build it!

One more thing, don't build it under something that produces lots of pollen.

kanemaui (author)2015-05-10

I've designed (I'm a Landscape Architect) and built (Owned my own Landscape Construction Company in SoCali and Hawai'i) small to large (OVER 2 acres) ponds/water features, so I thought I'd chime in on a related issue. If you intend to build a pond that will include 'Koi' fish, it is imperative you have a LARGE section of your pond AT LEAST 3 feet deep no matter where your pond will be located. The reasons are MANY and you can Google it for yourself. Many Koi are expensive and live a VERY LONG time. Insure the quality of their lives and safety by assuring your pond is 3 feet deep ~ ~ ~ Aloha ~

wmistler (author)2015-04-28

I just scraped my pond and creek in favor of a lawn. I was too impatient to have an expert come out and look at my site. Fir trees play havoc on a water feature, if I wanted to see the koi I had to dig algae out. Stay away from fir trees.

stephenmack (author)2015-04-28

I am definitely going to make this when we remodel our backyard! What I great idea. I will definitely vote for you.

bwangleon (author)2015-04-28

Really beautiful work! How exactly did you situate the pump intake? Through or over the liner? Thanks!

DragonTamer458 (author)bwangleon2015-04-28

There is a front plate on the skimmer that gets screwed in over the liner and acts as a waterproof gasket. So the liner actually goes through the skimmer and then a hole is cut in the liner where the intake is. I'll upload some more pictures so you can see this better.

bwangleon (author)DragonTamer4582015-04-28

Thank you. Look forward to seeing them.

DragonTamer458 (author)bwangleon2015-04-28

Okay. Updated. I hope that makes a bit more sense.

bwangleon (author)DragonTamer4582015-04-28

Yep. Thanks for the pics and description.

sshocke101 (author)2015-04-28

Thank you so much for sharing your idea! I also have wanted a forever and your plans seem to break it down so regular people could actually make one..I do go online but personally I think.sometimes I can become overloaded with the Internet info..and then.i don't even.know where to start..but if I print off your info and talk to a real person I can.make the adjustments to fit a yard like mine..which is flat and a small area (we live in the city) and somehow has no trees planted.! And I have been telling my guy all winter that's this next summer was going to be my year to make our backyard into a special almost retreat that I could go to... If you think of anything else that might help do d.i.y. Please email me and let me know of any other suggestions.... to be honest I'm getting a lot of things off the free section of Craigslist, it works for me right now ( personal things happening in my world) again thank you so much...I'm sure your mother loves seeing this beauty from her window.....

Hmm, Craigslist is a good idea for finding cheap raw materials. As for any help I can offer, this instructable pretty much covers it. Find someone in your area who has experience with this, seriously, it will help more the internet ever could. Show them pictures of your yard, show them sketches, have them sketch things for you. That is the best advice I can give you.

Elias Staris (author)2015-04-28

Bravo man! Like you said, we could have used some more photos, (for me the skimmer thing) but that's really not important. The main thing is that your post serves as an ispiration to a project I am on to and it's very nice to see beautiful things being created, thank you!

Thanks. I'll try to describe the skimmer setup a bit better. And take some more pictures.

Okay, I wrote more on the skimmer, I hope it's clear enough how that works.

Lorax98 (author)2015-04-28

You have done a fine job. We build ours from scratch (12'x16'x5' deep) and enjoyed hundreds of hours relaxing beside it for twenty years before we had to move to a new house. The buyers of our old property were also in the market for a pond and ours was exactly what they were looking for. We had fish (Koi & Goldfish) in our pond all year long, for twenty years, in Southern Alberta (Canada). Build it right, and it will provide stress relieving relaxation for years and years. The best advice you give is to find an expert and ask all the questions you can. Books are a good starting place, but you will avoid many problems by speaking with someone in your area that already has a pond.

Once again, great job on the pond (and the instructable)!

DragonTamer458 (author)Lorax982015-04-28

I'm so sorry you had to give it up. It really is a fantastic way to relax. I hope you can build another one someday.

emartin15 (author)2015-04-28

Beautiful, absolutely beautiful..

Sciencekid03 (author)2015-04-26

That's so cool

oçakıcı (author)2015-04-26

You can make solar powered one

I have solar lights on it, but I live in the Pacific Northwest. We get sun for 3 months out of the year.

mtairymd (author)2015-04-25

That looks awesome. You did a really nice job with the build.

DragonTamer458 (author)mtairymd2015-04-25

Thank you so much.
