Quality Pond Construction & Care Services in Fremont
Fremont has more genuine koi enthusiasts than almost anywhere else we work. That changes the conversation. A lot of Fremont clients arrive already knowing what they want from a pond, often having kept fish before, and the questions move quickly to filtration capacity, depth, and how the system will hold water quality through a warm summer.
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 a water feature should look native to its setting rather than imposed on it. Every project opens with a site visit and a real conversation about the yard and what you want from it.
Koi pond construction is our most technically demanding work and the service we are asked for most often. A koi pond that performs over years needs filtration sized to the actual fish load rather than the water volume alone, depth that gives fish a stable cooler layer through summer, and rock and planting work that creates a natural edge without choking circulation. We are Diamond Certified and hold a Master Aquascape Contractor designation, both earned on this kind of build.
The larger lots through the Mission San Jose and Irvington areas give a pond room to be properly proportioned, and many come with established gardens we design around rather than clear. We build with flexible EPDM liner instead of rigid shells, which matters on the clay soils common through the area. For clients wanting movement without fish, pondless waterfall construction delivers the sound and motion with far less ongoing management.
Our pond maintenance service supports clients who want the pond without the upkeep, covering seasonal cleanouts and water quality. Completed projects from across the region are on our featured projects page.

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.
Backyard Renovation
Imagine stepping outside into an outdoor living space designed around your family and the way you want to spend your time. We renovate backyards into cohesive sanctuaries, weaving water features, native plantings, and natural stone into one balanced design. Artistry and technical precision guide every project from concept to completion.
Landscape Design
Thoughtful landscape design is the foundation of every outdoor space we create. We plan the flow, plantings, and natural materials so your yard works as a whole, with room for water features, gathering areas, and lush greenery. Our designers blend creative vision with the ecological knowledge that keeps a landscape thriving.

Our History in Fremont
Fremont was formed from five older districts, and Mission San Jose, Niles, Irvington, Centerville, and Warm Springs each still read differently on the ground. Mission Peak rises on the eastern edge, Coyote Hills Regional Park sits toward the bay, and Central Park with Lake Elizabeth anchors the middle of the city. Lot sizes and garden maturity vary considerably between the districts.
That variation is most of what shapes a design here. A Mission San Jose property with a large established garden calls for a pond that integrates with decades of existing planting. A newer subdivision lot is a more open canvas where we build the landscape context along with the water. Both are common work for us.
We also serve neighboring Pleasanton and Dublin. If you are in Fremont and thinking seriously about a koi pond, we are happy to talk specifics.
Frequently Asked Questions - Fremont Remodeling
What size koi pond should I build in Fremont?
Depth matters more than surface area. A koi pond wants enough depth to give fish a stable cooler layer through summer and somewhere to hold when temperatures swing, and it wants filtration sized to the fish load you actually plan to keep rather than to the gallons. During the consultation we will look at your space and be direct about what it can support well and what would be overstocking it.
Can you build a pond into an established Fremont garden?
Yes, and a good share of our Fremont work is exactly that. Mature gardens are an asset, because the planting context that makes a pond look settled is already there. We plan the excavation and access around the trees and beds you want to keep, and we design the pond edge to meet the existing planting rather than fight it.
How do you keep koi healthy through a Fremont summer?
Through depth, filtration capacity, and continuous circulation. Warm water carries less dissolved oxygen and puts more load on the biological filter, so we build in headroom on both rather than to the minimum. Marginal and floating planting provides shade and takes up nutrients, which keeps the water clearer and the system more stable as temperatures climb.
Will herons or raccoons take koi in Fremont?
Predation is a real consideration anywhere in the Bay Area. We design with depth and built-in shelter so fish have somewhere to retreat, and we shape the pond edge to make approach less inviting for wading birds. It is a design consideration we build in from the start rather than something to solve after the fact.
How long does a koi pond build take in Fremont?
Most residential builds run one to two weeks from excavation through planting and fill. Larger ponds or projects with extensive rock work and integration into an existing garden can run two to three weeks. You get a clear timeline before we start and regular updates as the build progresses.
