We dig and shape the ground for decorative ponds, koi ponds, streams and waterfalls. Your landscaper or water feature installer brings the liner, rock, pumps and plants. We hand them a hole and a grade that are ready for that work.
Backyard Pond and Waterfall Excavation in Boise
A water feature looks like it's mostly rock and plants. Underneath, it's a hole with shelves, a stream bed with steady fall, and a mound of dirt built up for the waterfall to spill off. That earthwork is what we do. The liner, rockwork, pumps, filters and plants belong to your landscaper or water feature installer, and we don't build or maintain the finished feature.
We dig backyard ponds and waterscapes in Boise, Meridian, Eagle, Star and Nampa. Landscapers hire us when the dig is more than their crew wants to do with shovels, and homeowners call us to get the hole in before their installer shows up. For farm, stock or irrigation ponds on acreage, see our pond excavation page.
Who Does What on a Water Feature
Most backyard water features involve three or four trades. Gaps tend to show up between the dig and the liner, or between the conduit trench and the wiring, so it pays to sort out who handles what before a machine comes through the gate. Here's how the work usually splits:
- Designer or installer: layout, depths, liner and underlayment, rock, pump, skimmer, filter, plants and fish
- Us: locates, excavation, shelves, stream bed, waterfall mound, spoil removal and rough grading around the feature
- Electrician: power to the pump and lights, on a circuit they install and get inspected
- You: HOA approval if your subdivision needs it, and the final say on where it goes
We dig from the installer's drawing and paint marks. If they can be on site the day we dig, even better. A painted outline on the grass plus written depths for the shelves and the deep zone is usually enough to start. Questions come up once the hole is open, like a root where a shelf should go or a layer of caliche at the deep end, and it's faster when the installer can make that call on the spot.
Shaping the Pond: Shelves, Depth and Edges
A decorative pond isn't a bowl. Most have a plant shelf around the edge, often 8 to 12 inches below the water line, then a drop to a deeper middle. Koi ponds go deeper than a simple garden pond, commonly 3 feet or more, so the fish have cool water in July and room under the ice in winter. Your installer sets those numbers. We cut to them.
The rim has to be level all the way around, or the liner shows on the low side once the pond fills. We check grade around the edge as we go. We also leave room for underlayment and for any rock that sits on the shelves, so the finished depth comes out where the design says.
Streams, Waterfalls and Using the Dirt
Streams and waterfalls run on grade. Most backyards in Meridian and Star are close to flat, so the waterfall has to be built up. The dirt from the pond hole is usually the best material for it. We pile it where the falls will go, compact it in lifts so it doesn't slump under heavy boulders, and shape the stream bed with steady fall back to the pond.
On foothills lots in Boise you often have the opposite problem. The slope is already there, and the work is cutting a stream bed into it without loosening the hillside. Dirt the mound doesn't need can go into landscape contouring elsewhere in the yard or leave on a truck through our dirt removal service.
Where the Pond Sits in the Yard
Placement drives a lot of the work. A spot that looks good from the patio can mean a long trench for power, dirt that has to cross the whole lawn, or a pond sitting in the path of every rainstorm. Before digging we go over:
- Distance from the house. Keep the pond far enough off the foundation that a leak or overflow can't run toward it. The ground should still fall at least 6 inches in the first 10 feet away from the house.
- Runoff. A pond at the lowest point of the yard catches muddy water every time it rains. Setting it a little higher, with grading for landscaping around it, keeps it cleaner.
- Buried lines. We call Digline (811) at least two business days ahead. Sprinkler lines, pressurized irrigation and low-voltage lighting aren't marked, and they run through most Treasure Valley backyards.
- Trees. Roots slow the dig, and leaves end up in the water every fall.
- HOA and city rules. Many subdivisions in Meridian, Eagle and Star want plans before a water feature goes in. Deeper ponds can fall under different city rules than a shallow garden pond, so ask before you settle on a depth.
Power to the Pump
Pumps, filters, UV clarifiers and pond lights need power, and that's the electrician's job. What we can do is dig the trench for the conduit from the house out to the pond, at the depth the electrician calls for, and backfill once it's inspected. Same with a fill line from a hose bib or irrigation, which your installer or plumber connects. Our trenching services page has more on that kind of work.
Cost and Backyard Access
Backyard water features come down to access. A narrow side gate, a finished lawn and a fence all change how we get in and how the dirt gets out. Price depends on the size and depth of the pond, how much dirt goes into the waterfall versus a truck, soil like caliche, and how much of the yard needs protecting. We give free estimates and can bid straight off your installer's plan.
Timing matters too. Try to book the dig close to your installer's start date. An open hole collects rain, wet shelves can slump and need recutting, and a deep hole in the yard is a hazard with kids or dogs around. Before we arrive, move patio furniture and pots out of the path in, and keep pets inside on dig day.
