What it is
Pond builders pick the spot, check the soil, dig the basin, build the dam or embankment, and put in an overflow so heavy rain does not wash the dam out. Good clay soil matters, because sandy or rocky ground may not hold water.
Pond maintenance companies handle algae and weeds, aeration (fountains or bubblers that add oxygen), fish stocking, and dam and spillway repairs.
Before you dig, check with your local USDA Natural Resources Conservation Service (NRCS) office. They can help with soil questions and may know about cost-share programs.

Questions to ask a contractor
- How many ponds like mine have you built? Can I see one or talk to the owner?
- Will you test the soil first? What if it will not hold water?
- What kind of overflow or spillway will the pond have?
- Do I need a permit? Who handles it?
- Is fish stocking or aeration included?
- What upkeep will the pond need each year?
FAQ
Do I need a permit to build a pond?
Possibly. It depends on the size, the location, and whether a stream or wetland is involved. Large ponds and work in streams can involve state agencies or the US Army Corps of Engineers. Ask your county and your local NRCS office first.
Will my land hold water?
It depends on the soil. Clay holds water well; sand and gravel do not. A soil test or an NRCS visit can tell you before you spend money digging.
How do I keep algae down?
Common steps are aeration, keeping fertilizer runoff out, and adding the right plants or treatments. A pond maintenance company can recommend a plan for your pond.
