Water Features

Custom Water Feature Design and Installation That Transforms Your Yard

Pacific Outdoor Living builds the full California Waterscapes range: ecosystem ponds, koi ponds, pondless waterfalls and streams, fountains, natural swim ponds, repairs, and maintenance. We design each feature around natural circulation, biological filtration, stone, planting, and sound so it feels like it belongs in the landscape.

How we work

  1. An eroding hillside slope marked with a survey flag before construction began Before: the slope

    Site assessment and design

    We assess sunlight, drainage, slope, views, access, debris load, and where the feature should be seen and heard from the house.

  2. The existing patio and rear of the house before the waterfall and stream were excavated Before: existing patio

    Excavation and basin preparation

    We shape the basin, shelves, streambed, or hidden reservoir, then prepare a stable base for liner, boulders, equipment, and safe access.

  3. Conceptual landscape design plan labeling the three-tiered granite boulder waterfall and dry river bed Design plan

    Liner, boulders, and natural structure

    Rubber liner, underlayment, gravel, flagstone, boulders, and planted edges are installed so the feature looks natural rather than placed on top of the yard.

  4. Water cascading over granite boulders into the finished stream, close up Under construction

    Circulation and filtration

    Pump, skimmer, biological filter, optional UV, and plumbing are installed and tested. For koi and swim ponds, filtration is the core of water quality.

  5. The finished waterfall and stream bordered by boulders and grasses, with a fire-pit terrace beyond Finished

    Edging, planting, and finishing

    Stone edges, aquatic plants, water conditioning, lighting, fish readiness, and care instructions complete the feature.

Key decisions

Things worth knowing before a first consultation.

  • Ecosystem pond versus fountain versus pondless

    Koi ponds support life and need balanced filtration. Fountains are simpler. Pondless waterfalls offer water sound without an open pond.

  • Natural swim pond or decorative water feature

    Swim ponds are larger recreational ponds with more depth, stronger filtration, and clear choices about entry, bottom material, and plants.

  • Mechanical and biological filtration

    A skimmer removes leaves and debris. Biological filtration uses beneficial bacteria to break down nutrients and keep the system balanced.

  • Fish or no fish

    Koi are beautiful but require good filtration and enough depth. Goldfish and small fish can be easier. Fountains and pondless waterfalls need no fish.

  • Sunlight, shade, and debris

    Fish ponds prefer balanced sun and shade. Too much sun can increase algae, while nearby trees affect debris load and skimmer planning.

  • Sound, stone, and planting

    Rock placement, waterfall height, plant selection, and edge detailing determine whether the feature feels natural or decorative.

Investment and timeline

No quote written off a photograph can account for what your property is like.

What shapes the investment

  • Type of water feature (koi pond, fountain, pondless)
  • Natural swim pond size and swimming depth
  • Size and depth
  • Excavation difficulty and site prep
  • Liner quality and installation
  • Pump, skimmer, biological filter, optional UV, and wetland filtration
  • Edge treatment and landscaping

What shapes the schedule

  • Design and site assessment
  • Permit requirements (varies by city)
  • Excavation and soil conditions
  • Liner curing and water conditioning
  • Landscape integration and planting
  • Equipment setup and testing
  • Fish stocking or swim pond readiness

Why complete koi pond installation was drawn together with the rest of the property

Decking, drainage, utilities, planting, shade and lighting all bear on where a feature goes and how it gets built. Settling them on one set of drawings is what keeps conduit out of the wrong trench and stops paving being cut to fit afterward.

  • Feature placement Position for visibility from house and entertaining areas, while considering sunlight.
  • Circulation and filtration Skimmer, pump, and biological filtration sized for fish health, water clarity, and the chosen feature type.
  • Stone edging and integration Natural stone frames the feature and connects to surrounding hardscape.
  • Aquatic planting Plants provide food, shade, and habitat for fish and wildlife.
  • Landscape context Trees, shade, perimeter planting, and waterfall sound make the water feature feel natural.

Access, engineering, permits, finishes and scope vary a lot from one property to the next, so the investment and the schedule for your project are set once we have seen the site and the design is settled.

  • Piper the golden retriever standing in the dog-friendly pond built for this review

    From conception to completion CW was amazing! We asked for a dog friendly pond and got a magnificent waterfall and cool pond to enjoy!!!! We loved working with Chad and his crew. They enjoyed seeing the dogs enjoy Piper's Pond.

  • The finished natural pool conversion, with hand-placed boulders and a waterfall

    Chad, Mauricio and crew built our dream natural pool in May 2022. From start to finish the project was completed in 6 weeks. The crew was at the house every day on time and worked hard to complete the build. We converted our 20,000 gallon swimming pool to a 10,000 gallon natural pool and we couldn't be happier. The rock work (each one placed by hand) is truly artful. The waterfalls, four depth levels and two fish caves make for an aesthetic & safe aquatic environment. The koi love their new home. The plants are growing and two months in the water remains crystal clear. Jasmine's after sale support is tremendous. Thank you California Waterscapes for making our dream a reality!

  • The finished running creek built along a narrow side yard

    Look at this beautiful water feature, and guess what? It is in my yard! From scratch to the finished product, it took only 1 week... Chad helped us designed this water feature by using a long and narrow space against the wall, originally it was a wasted space. It does not take any of our useable space, just a natural-looking running creek that we see in the mountains. It is eco-friendly, requires very little maintenance. 0 chemical was ever thrown in it. My kids love to play inside the creek, wearing their rain boots, of course. And Chad was always there for me whenever I had a question. It is one of the best upgrades we have done for our house. We love it!

  • A close-up of the tiered rock waterfall built for this backyard Zen space

    Our Family is hooked, we need many more park benches to sit around this natural Zen space. We used to gather around the fire pit, now this is our summer night spot. Tranquility has overcome us and is saving us. WORTH EVERY PENNY. Who needs therapy anymore?! Feeling grounded.

Frequently asked questions

How deep should a koi pond be?

At least 18 inches, ideally 24-36 inches. Deeper ponds maintain stable water temperature and give koi room to escape predators.

How much maintenance does a koi pond require?

Daily feeding, weekly water checks, and seasonal filter cleaning. A well-designed system with good filtration requires 30 minutes per week.

How does California Waterscapes fit into the project?

California Waterscapes is part of the Pacific Outdoor Living family and shares the same office with our team. For specialized water-feature work, they are the crew we coordinate with while Pacific Outdoor Living manages the larger design-build plan, so your pond, waterfall, fountain, or swim pond fits the full outdoor space.

What is an ecosystem pond?

An ecosystem pond is designed as a balanced system. A skimmer removes surface debris, biological filtration supports beneficial bacteria, and plants, stone, fish, and circulation work together.

Can you build a natural swim pond?

Yes. Natural swim ponds are larger recreational ponds with added depth, larger filtration, optional UV, and entry details such as steps, a beach, gravel, or flagstone.

Can I have a water feature in full sun?

Koi ponds prefer 4-6 hours of partial shade. Full sun can increase algae. Fountains and pondless features work in more sun because they do not rely on the same fish-and-plant ecosystem.

Do I need a permit for a water feature?

Some cities require permits for ponds over a certain depth. We handle all permitting and safety compliance.
