How Much Does Pond Construction Cost in Kansas?
One national cost guide, updated in 2026, puts digging a farm pond at $5,000 to $20,000 on average. A second guide puts a farm pond at $3,750 to $13,000, based on size and terrain. The first guide adds that farm ponds and lakes can hit $70,000 or more.
Those are national market numbers, not our price list. Where a Kansas pond lands depends on the dam, the soil, the drainage area and the site work. We price pond construction after we look at the site.
What does a new pond cost in Kansas?
Here is how national cost guides price a new pond.
| What is priced | Published range | Source |
|---|---|---|
| Farm pond, average | $5,000 to $20,000 | National cost guide, 2026 |
| Farm pond, by size and terrain | $3,750 to $13,000 | Second national guide |
| 1-acre pond | $7,000 to $25,000 | National cost guide, 2026 |
| Larger farm or fishing ponds, per acre | $2,000 to $25,000 | National cost guide, 2026 |
| Ponds of 10 acres and more, per acre | $1,400 to $4,800 | Second national guide |
| Digging a larger pond, per cubic yard | $1.50 to $3.50 | National cost guide, 2026 |
| Geotechnical soil survey before a man-made lake | $1,000 to $5,000 | Second national guide |
| Kansas dam permit application, when the law applies | $200 | Kansas statute |
Per-acre prices usually drop as ponds get bigger, the second guide notes. One acre dug one foot deep is about 1,613 cubic yards of dirt. At the 2026 guide’s large-pond rate, each foot of depth across an acre runs about $2,400 to $5,650.
Why does the dam set so much of the price?
The NRCS pond handbook describes two kinds of pond. An embankment pond holds water behind a dam built across a watercourse. An excavated pond is dug into nearly level ground, so almost all of its water space is dug out.
On an embankment pond, much of the cost follows the dam. The handbook says the cubic yards of earthfill help predict the cost of the dam. It calls for a top at least 6 feet wide on a dam under 10 feet high. A dam 15 to 19 feet high calls for a 10-foot top. Upstream faces should slope no steeper than 3 feet out for each foot up.
For most pond dams under 20 feet high, the handbook puts the settlement allowance at about 10 percent. The dam is built that much taller than its design height. Fill goes on in layers about 6 inches thick. Where sand or gravel sits under the dam, the most common fix is a centerline trench filled with compacted clay.
An earth overflow spillway carries big storms around the dam. The handbook warns that a dam with too small a spillway will probably be destroyed in the first severe storm.
Will the soil on your land hold water?
The handbook rates clays and silty clays as excellent for holding a pond. It calls coarse sand and gravel usually unsuitable. For the dam itself, the ideal fill holds about 20 percent clay by weight.
Where the ground lacks clay, the fix costs money. The handbook’s clay blanket covers the pool and the upstream face of the dam. It takes at least 20 percent clay, compacted at least 12 inches thick for water under 10 feet. The second cost guide flags extra costs when clay has to be brought onto a sandy or rocky property.
Around Parker, the federal soil survey shows silt loam over a silty clay subsoil of about 45 percent clay. Several of Linn County’s main soils carry 45 to 53 percent clay below the surface. Every site still needs its own check. On some ridges, limestone or shale sits two to three feet down. In some limestone areas, the handbook warns, hidden crevices can empty a pond in a short time.
Unless the soil is known to be tight, the handbook calls for soil borings across the pool area. On limestone ground, its strongest clue is how well nearby farm ponds hold water. The NRCS Web Soil Survey maps the soil on any parcel.
How much land should drain into the pond?
A pond fed by runoff needs enough land draining into it to stay full through a drought. Too much drainage calls for expensive overflow structures for big storms, the NRCS handbook adds.
Its map gives the acres of drainage needed for each acre-foot of water stored. An acre-foot is one acre of water one foot deep. The map puts the counties around Parker between its 12-acre and 20-acre lines. By that guide, a pond storing 5 acre-feet near Parker wants roughly 60 to 100 acres draining into it. The handbook’s own example puts that pond in west-central Kansas at 175 acres or more.
Reliable local runoff data takes priority over the map. Land kept in grass or trees makes the most desirable drainage area. Silt from eroding ground cuts into a pond’s depth.
What does site work add before the digging?
The handbook lists four areas to clear: the dam site, the spillway, the pool and the borrow area for fill. The 2026 cost guide says rocky terrain and lots of trees can add $1,200 or more. Clay-like soil can too. The guide adds about $2,000 on average for land grading when an estimate leaves it out.
Our guide to what land clearing costs per acre in Kansas covers clearing a wooded site. If you are building a home or a shop on the same land, site preparation gets the pad ready too.
When does a Kansas pond need a state permit?
Kansas law puts dams under the chief engineer of the Kansas Department of Agriculture, Division of Water Resources. A barrier 25 feet or taller counts as a dam. So does one 6 feet or taller that stores 50 acre-feet or more with water up to its overflow spillway. Building one takes the chief engineer’s written consent or permit first. Some smaller dams, depending on hazard class, qualify for a simpler state registration instead of a full permit.
A dam permit application carries a $200 fee, plus maps, plans, profiles and specifications. A 1-acre pond averaging 6 feet deep holds about 6 acre-feet, far under the 50 acre-foot line.
A dam on a stream draining a square mile or more is a separate case. In eastern Kansas, the law calls that a designated stream, and building in one can need a permit too.
K-State Research and Extension in Johnson County adds more checks. A pond built to hold 15 acre-feet or more can also need a permit to appropriate water. It points anyone planning work in a stream or wetland to the Corps of Engineers in Kansas City. It also says to check with your county. Kansas law requires a Kansas 811 locate request at least two full working days before digging. The Division of Water Resources answers permit questions for your site, and we point you there.
How do you get a real number for your pond?
We look at the job and put the quote in writing.
We build new farm and home ponds with an excavator and a skid loader. We dig the basin and build the dam, then shape the banks and the spillway. See how we build a new pond. Already have a pond that has filled with silt? Pond cleaning is a different job with its own price. Call or text (620) 252-9314.
