Quality Pond Construction & Care Services in Walnut Creek
A well-built pond brings the backyard into focus. Everything else in the yard, the patio, the planting, the outdoor furniture, organizes itself around the water. Koi moving through a clear pond, a waterfall running over natural stone, aquatic plants rooted at the edge of a feature that looks like it belongs there. Pond construction in Walnut Creek delivers that quality of outdoor space for homeowners who are ready to invest in the yard they actually want.
California Aqua Pros has designed and built custom ponds and water features across the Bay Area since 1993. Greg and Marlo Purkey founded the company on the principle that every water feature should feel native to its setting, not installed. That means different designs for different properties, different filtration for different fish loads, and different approaches to rock work and planting depending on the sun, soil, and sight lines of each specific yard.
Koi pond construction is the most requested service we provide. A properly designed koi pond is a functioning ecosystem. The filtration carries the fish load. The depth keeps water temperatures stable through summer heat. The edges blend into the surrounding landscape. We are Diamond Certified contractors and hold a Master Aquascape Contractor designation, which means the technical standards behind the aesthetics are documented and real.
For homeowners who want the sensory experience of water without a full koi pond, pondless waterfall construction is often the right answer. The reservoir is buried underground, the waterfall and stream run on a recirculating pump, and the surface reads as a dry streambed or rock garden when the pump is off. No standing water, no depth concerns, full visual and auditory impact. We also design and install fountainscape features for courtyard spaces or formal gardens where the scale calls for something more contained.
Water gardens take yet another direction, organizing the design around aquatic plants rather than fish. The filtration is biological, driven by the plants themselves. The visual is softer and more seasonal. Water lilies, iris, rushes, and lotus all perform well in this climate, and a mature water garden develops its own ecological balance over time.
After construction, our pond maintenance service keeps the system healthy through every season. We handle filter cleaning, water chemistry, aeration checks, and the seasonal adjustments that matter most in a Bay Area climate. Scheduled service means you are never reacting to a problem, because we caught it first.

Pond Construction
Every pond we build begins with your vision and the natural character of your yard. Our team designs custom koi ponds and garden ponds with native stone, aquatic plants, and a balanced ecosystem that keeps the water clear and the fish healthy. The result is a tranquil backyard sanctuary that feels like it has always belonged there.
Pond Maintenance
A healthy pond is a living ecosystem, and our maintenance program keeps yours in ecological harmony year-round. We handle seasonal cleanings, water quality, and the small adjustments that protect your koi and aquatic plants. With our team caring for the details, you get to simply enjoy the water.
Fountains & Water Features
A fountainscape brings the calming sound of moving water to a patio, entryway, or garden without the space a full pond requires. We design and install custom fountains and water features that suit the scale and style of your home. Each one is built for lasting beauty and quiet, dependable operation.
Pondless Waterfall
A pondless waterfall delivers the artistry and sound of flowing water with minimal upkeep and no open pool. Water disappears into a hidden reservoir and recirculates, so you enjoy a natural stream or waterfall feature that fits busy yards and young families. It is one of the most popular ways to bring nature into your backyard.

We renovate backyards into cohesive sanctuaries, weaving water features, native plantings, and natural stone into one balanced design.

Our History in Walnut Creek
Walnut Creek sits at the base of Mount Diablo, with open space corridors running up into the hills above Northgate and Shell Ridge. The Iron Horse Regional Trail cuts through the heart of the city, and Heather Farm Park anchors the northern neighborhoods with its community gardens and open water. These aren’t background details for people who live here. They are part of why Walnut Creek homeowners think about nature the way they do, and why a well-designed pond feels right in a backyard along Rudgear Road or up in the Las Lomas hills.
We have worked in Walnut Creek for most of our thirty-plus years as a company. The city’s mix of older ranch-style properties near downtown and newer construction along the hillside edges gives us a wide range of yard types and client expectations to design around. Walnut Creek homeowners tend to ask detailed questions and hold their contractors to a high standard. That suits us well.
We also serve the neighboring community of Livermore to the southeast. If you are in Walnut Creek and ready to move forward, reach out and we will schedule a site visit.
Frequently Asked Questions - Walnut Creek Remodeling
What koi pond sizes work for Walnut Creek backyards?
Walnut Creek yards range from compact urban lots near downtown to larger hillside properties above the city. For smaller lots, we build formal koi ponds with vertical rock faces that maximize depth without requiring a large footprint. Larger properties support naturalistic designs with streams, planted edges, and multiple water levels. We size every pond to the yard during the consultation.
How does summer heat affect a koi pond in Walnut Creek?
Walnut Creek regularly hits the 90s in summer, which drops dissolved oxygen and stresses fish if the pond is not properly designed. Adequate depth, good aeration, and a filtration system matched to the fish load are what protect koi through heat spikes. We factor local climate conditions into every design decision so the pond performs through July and August, not just spring.
Can aquatic plants survive Walnut Creek winters in an outdoor pond?
Most aquatic plants common to Bay Area ponds, including water lilies, iris, and native rushes, handle Walnut Creek winters without any issue. A few tropical varieties may need to come indoors or be treated as annuals. We recommend planting combinations based on your pond’s sun exposure and how it is sited relative to the prevailing shade patterns in your yard.
Do you work with existing landscape designs?
Yes. Many of our Walnut Creek projects integrate a new pond or water feature into a yard with established planting, existing hardscape, or an existing pool. We coordinate with homeowners and, when needed, with their landscape team to make sure the water feature fits the overall design rather than competing with it.
What does routine pond maintenance involve?
A well-built pond with complete filtration needs consistent but manageable attention. Skimmer baskets get cleared every week or two, filter media is rinsed monthly, and water chemistry should be checked periodically throughout the season. Our pond maintenance service handles all of this on a regular schedule so the pond stays healthy without becoming a second job.
