Koi & Ecosystem Ponds
Naturalistic ponds with proper depth, aeration, and filtration that keep koi healthy and water clear year round.
Koi ponds, ecosystem ponds, waterfalls, streams, fountains, and pondless features, designed as true habitats and built so they look, sound, and behave like nature put them there. WETYR Pools builds living waterscapes that grow more beautiful with every passing season.
There is a profound difference between a pond and a hole with a liner and a pump. The first is a living system that takes care of itself; the second is a chore that fights you every weekend. Most of the ponds homeowners regret were sold as kits, dropped into the ground, and left to fend for themselves. They turn green, they leak, the fish struggle, and within a season the novelty has curdled into a maintenance headache.
WETYR Pools builds the opposite. A genuine ecosystem pond is engineered so that rock, gravel, aquatic plants, fish, beneficial bacteria, aeration, and mechanical filtration all work together as one self-balancing whole. Each element does a job. The plants and bacteria consume the nutrients that would otherwise feed algae. The rock and gravel host the bacteria and give the system enormous surface area. The fish add life and movement and, in a balanced pond, contribute to the cycle rather than overwhelming it. The result is water that stays clear with a fraction of the effort, and a feature that does not merely survive but visibly improves with age.
That is the standard every WETYR waterscape is held to. Whether you want a quiet reflecting pool by the entry, a koi pond deep enough to overwinter prized fish, or a multi-tier waterfall you can hear from inside the house, we design it as a habitat first and a decoration second. Build it as a habitat and the beauty takes care of itself.
Every WETYR waterscape is custom, shaped to your land and the way you want to experience water. Most projects begin from one of these forms.
A true koi pond is built for the fish first. Koi are long-lived, intelligent, and surprisingly large at maturity, so the pond must offer real depth, generous volume, strong aeration, and filtration sized well above the minimum. Adequate depth protects fish from predators and from temperature swings, while shaded zones and planted margins give them refuge and keep the water cool. Built correctly, a koi pond becomes a relationship: the fish learn your routine, come to the surface to greet you, and live for decades. Built as a kit, it becomes a slow disappointment. We design koi ponds for the life of the fish, not the length of a warranty.
An ecosystem pond is the broad category of self-balancing water gardens that may or may not be stocked with koi. Edged with natural boulders and gravel, planted with lilies and marginal plants, and circulated through a waterfall or stream, it is designed to look as though a spring surfaced in your yard. These ponds are the lowest-effort water features we build because the biology does the work. They draw birds, dragonflies, and frogs, and they turn a flat lawn into a small, living landscape.
Moving water is what makes a waterscape come alive. A waterfall delivers sound, sparkle, and the oxygen that keeps the whole system healthy, and a stream extends that movement across the yard so the feature reveals itself gradually rather than all at once. We build waterfalls in single dramatic drops or in gentle multi-tier cascades, always from natural stone set so convincingly that the water looks like it found its own path down.
A pondless waterscape gives you all the drama of a waterfall and stream with no open body of water. The water recirculates through a hidden underground reservoir filled with rock, so there is nothing for a child to fall into and far less to maintain. Pondless features are the right answer for families with young children, for front yards, for sloped sites, and for anyone who wants the sound of moving water without committing to fish and aquatic plants. They can also be switched off entirely when you travel.
Not every space wants a full pond. A bubbling boulder, a ceramic urn, a basalt column, or a millstone fountain brings the calm of moving water to a courtyard, an entry, or a tight patio. Like pondless waterscapes, these disappearing fountains recirculate through a concealed basin, which makes them safe, compact, and simple to live with. They are the perfect first water feature and a beautiful accent alongside a larger pond.
Where the architecture is formal, the water should be too. A reflecting pool, a rill, or a geometric basin trades naturalistic boulders for clean lines, precise edges, and a still surface that mirrors the sky and the house. Formal water pairs beautifully with modern and classical homes alike and can incorporate scuppers, spouts, or a quiet sheet of moving water at the edge.
One of our favorite projects is the combination of a swimming pool with a natural pond, stream, or waterfall. Designed together, the two read as a single landscape: you swim in clean, balanced pool water while a koi pond and cascade sit just beyond, sharing the same stonework and planting. The result is a backyard that feels less like a yard with a pool and more like a private resort.
The first thing people notice about a well-built waterscape is not how it looks. It is how it sounds. Moving water masks traffic and neighbors, settles the nervous system, and turns a backyard into a place you actually want to sit. That sound is engineered, not accidental. The pitch and volume of a waterfall depend on the height of each drop, the width of the spill, the flow rate of the pump, and the way the stone is set beneath the lip. A few inches of adjustment is the difference between a gentle trickle and a roar.
WETYR Pools builds every cascade by hand, from natural stone, tuning the sound as we go. We set boulders so the water disappears behind them and reappears, place underwater stone to break and brighten the flow, and run streams with enough drop to keep moving and enough turns to stay interesting. Moving water is also the engine of a healthy pond: it adds oxygen, drives circulation, and pushes debris toward the filtration. A waterscape that sounds beautiful and a waterscape that runs clean are, properly built, the same waterscape.

Beneath those four stages is a careful sequence. After the design is approved, we mark the layout on the ground so you can see the true footprint and adjust it before a shovel moves. Excavation shapes the basin with the shelves, depths, and planting zones the design calls for. The liner or shell goes in, then the underlayment and the structural rock. Boulder placement is the art of the build: every stone is chosen and set by hand so the edges look natural and no liner is ever visible.
Next comes the mechanical heart of the pond. The skimmer, the biological filter, the plumbing, and the pump are installed and concealed, and the waterfall and stream are constructed and tuned for sound and flow. Gravel is set over the liner to host bacteria and finish the floor. Then the pond is filled, the water is treated and balanced, and aquatic plants are placed. Fish are introduced last, only once the system has had time to establish, so they enter a pond that is already alive and ready for them.
Aquatic plants are not decoration. They are the working filter of a healthy pond. Water lilies shade the surface and starve algae of the light it needs. Marginal plants such as iris, pickerel rush, and canna grow along the shelves and pull dissolved nutrients straight out of the water. Submerged oxygenators work below the surface, and a bog garden, where water is forced slowly up through a planted gravel bed, can polish a pond to startling clarity. A pond planted correctly is a pond that fights its own algae.
The fish complete the picture. Koi are the headline, but goldfish, shubunkins, and native species all add movement and life, and in a balanced system they graze, stir the water, and become part of the cycle rather than a burden on it. The key is restraint: a pond overstocked with fish will always struggle, while a pond stocked sensibly and planted generously stays clear with very little intervention. We design every WETYR pond with that balance built in, and our service plans keep it that way through every season.
Clear water is not luck. It is the visible result of a filtration and circulation system that was sized and built correctly. Most green, struggling ponds were not failures of effort; they were failures of design, fitted with a pump too small to turn the water over often enough and a filter that could not keep pace with the life in the pond. WETYR Pools sizes every system to the real volume of the pond and the real bioload it will carry, then builds in headroom.
A complete system works in two stages. Mechanical filtration, beginning at the skimmer, captures leaves and debris before they sink and decay. Biological filtration gives beneficial bacteria the vast surface area they need to convert fish waste and dissolved nutrients into harmless compounds, breaking the cycle that feeds algae. Circulation ties it together: the entire volume of the pond should pass through filtration regularly, and the waterfall and returns should be placed so there are no dead zones where debris settles and water stagnates.
Aeration is the quiet hero. Oxygen keeps fish healthy, fuels the beneficial bacteria, and is most critical on the warm summer nights when plants stop producing it and warm water holds less of it. We design waterfalls, streams, and, where needed, dedicated aerators to keep oxygen high around the clock. We also choose energy-efficient pumps, because a pond runs continuously and the difference between an efficient pump and a wasteful one is felt on every utility bill for the life of the feature. Done right, a WETYR waterscape is clear, healthy, and inexpensive to run.
Waterscapes range widely in price because they range widely in scope. A disappearing fountain is a modest, contained project. A large koi pond paired with a multi-tier waterfall and a meandering stream is a significant landscape installation. Rather than quote a meaningless average, we explain what actually moves the number so you can steer your budget toward what matters most to you.
The biggest factors are the size and depth of the pond, which drive excavation, liner or shell, rock, and filtration; the amount of stonework, since hand-set boulders and long streams are labor-intensive; the length and number of waterfall drops; the filtration and aeration package; the planting and the initial fish stock; and site conditions such as access for equipment, grade, and how far the feature sits from power. A pondless waterscape often costs less than an equivalent pond because it carries no fish, fewer plants, and a simpler biology, while a koi pond built for prized fish carries more depth, more volume, and more filtration.
Whatever the scope, WETYR Pools delivers a fixed, itemized proposal before any work begins. You see exactly where every dollar goes, and the price you approve is the price you pay. We would rather lose a bid than win one by hiding costs that resurface later as change orders. A living waterscape is a long-term addition to your property and your daily life, and it should be planned with that honesty from the very first conversation.
A waterscape is part architecture, part biology, and part craft, and that combination is exactly why so many ponds disappoint. A landscaper installs a kit and never thinks about filtration. A pump dealer sizes equipment and never thinks about how the stone is set. A handyman sets boulders and never thinks about the fish. Quality leaks at every handoff. WETYR Pools is built the opposite way: design, engineering, stonework, filtration, planting, and long-term care all live under one roof.
That single line of accountability is why our ponds run clear, why the waterfalls sound the way they were drawn to sound, and why the same people are still there years later to keep the feature healthy. Because we also maintain what we build, we have every incentive to build it right the first time. You get one point of contact, one standard, and one company whose reputation is on the line from the first sketch to long after the first fish.

Clear answers to the questions homeowners ask most before starting a pond or waterscape project.
A properly built ecosystem pond is surprisingly low effort because plants, rock, fish, beneficial bacteria, and correctly sized filtration keep it balanced on their own. The ponds that become a chore are almost always undersized kits with no biology behind them. We design self-sustaining systems, and our service plans handle seasonal care so you can simply enjoy the water.
It depends entirely on scope. A disappearing fountain is a modest project, while a large koi pond paired with a multi-tier waterfall and stream is a significant landscape installation. Price is driven by size and depth, the amount of hand-set stonework, the filtration package, planting, fish stock, and site access. After an on-site consultation we deliver a fixed, itemized proposal so you see exactly where every dollar goes.
Yes. Koi thrive when the pond is built for them, with real depth, generous volume, shaded zones, strong aeration, and filtration sized above the minimum. Adequate depth protects fish from predators and temperature swings. We design every koi pond around the long-term health of the fish, which routinely live for decades in a well-built pond.
A pondless waterscape gives you a flowing waterfall and stream with no open body of water. The water recirculates through a hidden underground reservoir filled with rock. There is nothing for a child to fall into and far less to maintain, which makes pondless features ideal for families with young children, front yards, and anyone who wants the sound of moving water without fish or aquatic plants.
Green water is an algae bloom feeding on excess light and nutrients. We prevent it at the design stage by sizing filtration and circulation correctly, shading the surface with water lilies, planting marginals and bog gardens that consume nutrients, and keeping the fish load sensible. Clear water is the visible result of a balanced ecosystem, not a chemical you keep adding.
Definitely. Pairing a waterfall, stream, or koi pond with a swimming pool is one of our favorite projects. Because we design and build both, we resolve them together so they share the same stonework and planting and read as one cohesive landscape rather than two features competing for attention.
A disappearing fountain can be completed in a few days. A modest ecosystem pond typically takes one to two weeks, and a large koi pond with extensive waterfalls and streams can take several weeks depending on the amount of stonework and site conditions. You receive a clear schedule before we begin, and our own crews carry the project from excavation to the day the fish go in.
Yes. We service and rehabilitate existing ponds and waterscapes, including failed kit ponds. Many of those features can be brought back to health by correcting the filtration, the circulation, the rock work, or the planting balance. We will assess what you have and tell you honestly whether it should be repaired or rebuilt.
A healthy pond attracts welcome wildlife such as birds, dragonflies, and frogs, which are signs the ecosystem is balanced. It does not breed mosquitoes, because moving water and fish prevent larvae from surviving. Still, stagnant water is the problem, and a WETYR pond is always circulating. Predators such as herons can be designed around with depth, shelves, and planted cover.
