Can I create a Waterfall in my large pond too? – Pond & Lake Q & A

Can I create a Waterfall in my large pond too? Jason – Grand Junction, CO

You don’t have to own a water garden to enjoy the sights and sounds of a waterfall in your backyard. Although they are built a bit differently, it is completely feasible to construct a waterfall in your large farm pond.

Unlike a water garden, your waterfall feature does not have to boast filter media pads, lava rocks, or bio balls. Your farm pond waterfall focuses more on sound and appearance than it does productivity. All is not lost however; your waterfall will provide a small amount of aeration and circulation in the pond but not enough on its own to sustain the entire water body. Since your pond is not dependant on the waterfall for filtration or aeration you can turn it off and on at will and there is no need to run it 24/7. This is great as it can save you money in energy costs and wear and tear.

The materials required to construct your farm pond waterfall are similar to those of a smaller water feature with a few exceptions. You will obviously be building at a larger scale in comparison to a water garden so large high flow pumps are the weapon of choice to deliver water to the top of your falls. Professional quality pumps like the Norus 7,000 or Tidal Wave 10,000 are perfect for high volume, high head pressure applications. Instead of using a skimmer box to house your pump you will want to rely on a Pump Vault for protection. Available in multiple sizes, a pump vault will not only prevent solids from entering the pump but it will shield swimmers, boaters, or fishermen from coming in contact with the unit. You will want to put the pump in an area that is generally unused for recreation as well as in an area not in danger of running dry if the water levels drop in the warmer seasons. Just like a Koi pond, you will want to install a Pond Liner and Underlayment, for your water fall and stream to direct flow and prevent water loss. Your Black Waterfall Foam will come in handy for creating sealed areas between rocks and water fall boxes to further aid in flow direction. You will also still want to use a large Waterfall Box, or a couple smaller ones to provide a basin to collect water so the waterfall will spill evenly over the rocks instead of looking like a fireman’s hose. Because you will be dealing with a higher flow rate, a larger diameter tubing will be needed. Each diameter can handle a certain amount of flow; here is a handy chart to help you choose the best size tubing for your particular scenario.

Finding Proper Tubing Size for Optimum Gallons Per Hour (GPH)

Pump Size Tubing Size
500 GPH 1/2”
900 GPH 3/4”
1,500 GPH 1”
2,700 GPH 1-1/4”
3,600 GPH 1-1/2”
5,400 GPH 2-3/4”
13,500 GPH 3”
21,000 GPH 4”
42,000 GPH 6”

Maintaining your waterfall is as simple as using Oxy-Lift Defense to break debris free from the rocks and then rinsing the stream off with a hose or by running the waterfall pump.

  1. How much energy do the pumps consume?

    • Energy consumption will really depending on the size pump you are using and it’s specific energy requirements. Most pumps will list their energy needs right on the label. If you are looking for a cost estimate on running the pump you can use the following formula:

      Multiply Amps x Volts to determine Watts
      Multiple Watts x Number for hours per day you plan to run the pump
      Divide that number by 1,000. This will equal the kilowatt hours
      Then multiply by what you are charged per kilowatt hour (found on your energy bill)
      This will give you a cost to run per day.
