Many other factors also affect the cost of building a pond, including:

  • Consultation – Some pond contractors charge $80 to $450 for an on-site visit to assess and design the pond based on your location, soil type, intended use, and desired features.

  • Size, depth, & shape –Larger, deeper ponds require more equipment, labor, materials, and more powerful pumps and filtration systems.

  • Government funding –Building a larger pond or lake may qualify for a grant if the new pond provides environmental conservation benefits.

  • Location & vegetation – Sloped sites require more labor and excavation. Ponds built near trees require more maintenance due to falling debris and underground root intrusion.

  • Accessibility –Labor typically costs more if the new pond site is difficult to reach with a truck or other large equipment.

  • Extra features – Add-ons like a bridge, fountain, lighting, statue, or waterfall increase the total.

  • Equipment – Some ponds require a pump and filtration system. If needed, choose a pump big enough to circulate the full volume every 1 to 2 hours.

    • A pond pump costs $100 to $1,500+, depending on the size.

    • Filtration systems cost $100 to $2,000+ and may be biological, mechanical, or both. Some waterfall features double as filters.

    • An automatic dosing system costs $150 to $700 and treats the pond at regular intervals to maintain the water quality and reduce maintenance.

  • Bottom drain – A bottom drain costs $120 to $450 before installation. Bottom drains clear debris from the pond floor and add convenience to draining, cleaning, and maintaining the pond.

  • UV sterilizer – UV sterilizers cost $180 to $600 and maintain water clarity. A UV sterilizer is not always needed but is beneficial for ponds with faster plant growth from full sun exposure.

  • Heater – A pond heater costs $50 to $3,500 and regulates a pond's water temperature during winter months.

  • Permits / codes / HOA – Many cities require a permit to build a pond. HOAs may have other restrictions or fees. Contact local building authorities for guidelines and requirements before building a pond.

  • Fencing – Some cities require a fence around a pond.

  • Soil type – A geotechnical soil report costs $1,000 to $5,000 on average to determine the land's suitability for pond building. Rocky or sandy soils are not ideal for ponds and may require adding clay-heavy soil for a structurally sound pond or lake. Digging in rocky soil also requires more labor.

  • Underlayment – Pond underlayment costs $0.25 to $0.40 per square foot and protects the pond liner from punctures or tearing.

  • Pond liner – a pond liner costs $0.50 to $3.50 per square foot depending on the material. Liner materials include PVC, rubber, fiberglass, concrete, and bentonite clay. Clay and fiberglass are heavy, and transportation is often cost prohibitive if not locally sourced.

  • Labor costs

    • Excavation costs $2.50 to $15.00 per cubic yard or $300 to $3,200 to dig an average backyard pond. Most excavators have a $500 to $800 minimum project fee.

    • Dirt removal costs $140 to $230 per cubic yard or $1,400 to $2,300 per truckload (10 cubic yards).

    • Land leveling or regrading a yard costs $500 to $5,000, depending on the project size.

    • Land clearing costs $1,500 to $3,000 per acre for a lightly wooded lot and $7,000+ per acre for a heavily wooded lot.

Pond maintenance and equipment

Pond maintenance costs $400 to $2,900 per year on average, depending on the size, type, location, and debris accumulation. Most ponds require regular maintenance, such as skimming debris from the surface, cleaning or changing the filters, checking the water quality, and cleaning the bottom of the pond as needed.

DIY pond cost

A DIY pond costs $550 to $6,100 on average for a kit with everything required to build the pond except for equipment to dig the hole. Building a pond yourself with individual components may cost more or less than a pond kit, depending on the features.

Planning is the most important part of the DIY process. Follow these steps for a successful and long-lasting backyard garden pond:

  1. Decide the desired size, location, features, and intended use. Ponds fed by groundwater should be in a level, low-lying area.

  2. Confirm the pond building plan follows all local, state, and federal building and environmental protection laws and HOA guidelines if applicable. Pull any necessary permits.

  3. Determine if the soil is adequate for building a pond.

  4. Clear the site of trees, bushes, rocks, and debris.

  5. Mark out the pond shape and any filter and feature locations on the ground with landscaping spray paint or string.

  6. Construct an embankment if needed. Sloped land typically requires an embankment or dam.

  7. Dig the hole, creating multiple levels if desired. Dig right-angle shelving at least 18" around the pond's perimeter for rocks and aquatic plants. For larger ponds:

    1. Renting a mini-excavator costs $200 to $700 per day.

    2. Backhoe rental costs $200 to $450 per day.

    3. A front-end loader may be used for ponds up to 1/8th an acre.

  8. Backfill as needed to set the skimmer and filters.

  9. Ensure the pond is level.

  10. Lay the underlayment down if applicable, followed by the pond liner, extending the liner at least 12" beyond the edges.

  11. Secure the liner to the filtration components with plant-safe sealant. Use heavy rocks to secure and conceal the liner around the pond's edge.

  12. Install the submersible pump if applicable.

  13. Fill the pond with water and test or have it tested professionally for safety before adding plants or fish.

Pond building FAQs

Does a pond increase property value?

A pond may increase property value by 5% to 10%, depending on the size, condition, and location. A well-established, low-maintenance pond with clear water, trophy-size fish, or high-end aesthetic features adds substantial value, but a neglected, overgrown pond requiring significant work may devalue the property.

How long does it take to build a pond?

Building a pond takes 1 day to a month or more, depending on the pond and crew size, design complexity, and excavation equipment used. Weather and installer experience also affect the timeline. Most small to medium size backyard ponds take 2 to 5 days for professional installation.

What do you need to build a pond?

To build a pond, you need:

  • Shovel – A shovel or equipment to dig the pond.

  • Liner – Keeps the water from seeping into the ground.

  • Large or heavy rocks – Conceal and secure the liner around the edge of the pond.

  • Pond pump – Moves the water through a filter.

  • Filter – Removes debris from the water being pushed through by the pump.

  • Skimmer – Removes debris from the water surface like a pool skimmer.

  • Electricity – A GFCI outlet at least 10' from the pond.

Many backyard ponds also include:

  • Underlayment – Extends the liner's life by protecting it from punctures from roots or sharp rocks.

  • Bottom drain – Removes debris from the pond's floor, reduces maintenance, and adds convenience when draining the pond.

  • Pond plants – Provides an aesthetic element and natural water filtration

  • Lighting – Improves safety and allows more visibility for fish and wildlife activity.

  • Waterfall – Provides agitation and an eye-catching feature.

Do I need a permit to build a pond?

You may need a permit to build a pond, depending on the size, location, and elevation. Check with local building and zoning authorities for the requirements in your area. Check with your HOA if applicable for guidelines or restrictions.

How much does it cost to remove a pond?

The cost to remove a pond depends on the size, type, and location. A pump to remove the water costs $50 to $150+. Fill dirt or topsoil costs $5 to $50 per cubic yard for the dirt and $200 to $400+ on average for landscapers to deliver and spread it.

Other pond removal costs to consider:

  • Relocating fish and wildlife adds time and labor.

  • Large stone or concrete liner removal may require a jackhammer.

  • Removing the pond may require a permit if the removal affects public property or a public water source.

Who builds ponds?

Pond contractors have the expertise to build a pond with structural integrity and a healthy ecosystem. Some landscapers offer pond design and installation. Small ponds may be DIY friendly, depending on the location, soil, and intended use.

Can I dig a pond in my backyard or property?

Whether you can dig a pond on your property depends on the location, soil type, elevation, pond size, potential environmental impact, and local regulations. The permit process determines whether your proposed pond improves or negatively affects the surrounding landscape and ecosystem.

  • Most areas have laws about a dam or pond's proximity to nearby creeks, rivers, or streams.

  • Consult your local National Resources Conservation Service (NRSC) extension and local building authorities to confirm whether your soil and property can support a pond.

  • Digging a pond on a slope requires leveling it or building a dam or retaining wall on the slope's downward side. An alternative option is using the slope to create waterfalls or tiered landscaping.
