Dig a Small Pond on My Property — Approvals, Digging and Spoils
You have room on the lot or the acreage for a pond, and want to know what it takes and who has to sign off before a machine shows up.
Want to dig a small pond on your property? In Minnesota, check approvals first. The state protects wetlands and public waters, so a pond may need approval from the DNR, the watershed district and the county or city before digging. JMB Builders checks that before quoting, then digs and shapes the pond, sets a liner or compacts a clay bottom, and spreads or hauls the spoils. Priced per project.

The hard part of a pond in Minnesota is often not the digging. Minnesota protects wetlands and public waters, and a low, wet spot that looks like a good pond site may itself be a wetland. Digging or filling one without approval can mean an order to restore it. Shoreland lots near lakes and rivers have their own county or city rules. Depending on the site, the DNR, the watershed district and the county or city can all have a say.
So the first step is a look at the site and a call to the agencies before we quote. If it is clear, or once approvals are in hand, the digging is straightforward: a staked outline, gentle side slopes for safety and to keep the banks from slumping, and a shape that fits the ground.
Whether it holds water depends on the soil. Heavy clay, compacted in the bottom, can hold water on its own; sandy soil needs a liner. A dug-out pond that reaches groundwater fills and drops with the water table. The dirt that comes out is a lot of material, and we plan where it goes before we dig.
What you supply
- The address or parcel, and where on the property you want the pond
- What the pond is for: looks, wildlife, livestock water, a skating spot
- Photos of the site in spring and late summer if you have them, to show how wet it gets
- A survey or aerial with property lines, wells, septic and drain field marked
What JMB supplies
- A site visit and a check with the DNR, watershed district and county or city on what approvals apply
- Gopher State One Call locate before digging
- Pond staked out and dug with an excavator, with gentle side slopes
- Clay bottom shaped and compacted, or the hole prepared and a liner set, as quoted
- Spoils spread and graded, built into a berm, or hauled off
- Banks topsoiled and seeded with erosion blanket, and silt fence where needed during the work
- Photos in your job folder
How it is priced: per project
Quoted in writing from your photos within one business day. What moves the number:
- Size and depth of the pond and how much material comes out
- Soil: clay that can hold water vs. sand that needs a liner
- Groundwater that has to be pumped to dig
- Spoils spread on the property vs. hauled off by truck
- Approvals, surveys or engineering the agencies require
- Access for an excavator and trucks, and ground protection
- Seeding, erosion blanket and silt fence around the work
Send the address, a photo of the spot and a rough size. We check the approval question first. If the site is a wetland or public water, we tell you what that means before anyone spends money on a design.
How long it takes
Approvals: from a quick answer to several weeks or more, set by the agencies. Digging a small pond: usually a few days once approved, plus seeding the banks.

Situations and options
Dug-out pond
Where the water table is high, the pond is dug down into it and fills with groundwater. Level rises and falls with the seasons.
Clay-lined pond
In heavy clay soil, the bottom and sides are shaped and compacted so the clay holds rain and runoff without a liner.
Lined backyard pond
In sandy soil or for a smaller ornamental pond, the hole is shaped, padded and fitted with a flexible liner, then the edges are buried or covered with rock.
Spoils made into a berm
The dirt dug out is shaped into a low berm or used to fill a low area, instead of paying to haul it away.
Dig a Small Pond on My Property — Approvals, Digging and Spoils: questions, answered
Do I need a permit to dig a pond in Minnesota?
Often, yes, and it depends on the site. Minnesota protects wetlands and public waters, so digging in or near one can need approval from the DNR, the watershed district, or the county or city that runs the wetland rules. Shoreland lots have their own rules too. We check with the agencies before we quote.
Can I turn a wet spot in my yard into a pond?
Maybe not without approval. A spot that stays wet may be a regulated wetland, and digging it out into a pond can count as altering a wetland. Ask before you dig; the local wetland authority can say whether it is regulated and what, if anything, is allowed.
Does a pond need a liner or will clay hold water?
Heavy clay, shaped and compacted, can hold water on its own. Sandy or gravelly soil will not, and needs a liner. Test holes on site show which you have. Small ornamental ponds are usually lined either way.
What do you do with the dirt from digging a pond?
It is either spread and graded on the property, built into a berm or used to fill a low area, or loaded and hauled off. Spreading it costs less. Where it can go can also be limited by the same wetland and shoreland rules as the pond, so it is part of the plan from the start.
How deep should a small pond be?
Deep enough in the middle to hold water through a dry summer, with gentle side slopes for safety and so the banks do not slump. Depth also depends on the purpose, the soil and the water table. We set it with you on site, within whatever the approvals allow.
How long does it take to dig a pond?
The digging on a small pond usually takes a few days. Getting approvals can take much longer and depends on the agencies. Seeding and erosion control on the banks finish the job.
