Pond Construction and Excavation in Corvallis, Montana

Custom Ponds Shaped to Suit Your Landscape

The right pond quietly reshapes how a property works, giving you water for livestock, irrigation for pasture, or a still place to fish and watch wildlife settle in. At Bohlander Construction, we build and restore ponds for rural landowners across Corvallis, Montana and throughout the Bitterroot Valley, from Hamilton and Stevensville to Florence and Missoula. A pond that truly holds water starts long before the digging, in how we read your soil, your slope, and how the land already moves water across itself.


Every basin we shape is built around its purpose. We dig to the proper depth, set stable slopes, manage the spillway, and grade banks that resist erosion rather than sliding into the water. Stock ponds, irrigation ponds, and recreational features each get a design suited to how you will use them. For tired ponds thick with silt and weeds, we drain, dredge, and restore lost depth, bringing a neglected water feature back to life instead of starting over from scratch somewhere else.


Our 13 years moving earth here mean we understand how local ground holds or loses water, and we build accordingly. Because our excavators and haul trucks are our own, the work stays efficient and pricing stays honest, with no rented iron padding the bill. You talk straight with the owner at every single turn, so choices about depth and shaping happen fast. When you can picture water on your land, share your full plans on our contact page and we will map it out.

Our Pond Services

  • Stock Pond Construction

    Livestock need a steady water source, and a well built stock pond delivers it. We locate the pond where the land drains toward it, dig to a depth that resists freezing and evaporation, and shape banks that cattle can reach without eroding edges.

  • Irrigation Pond Excavation

    Holding water for the dry months keeps pastures and crops alive. We excavate ponds that capture runoff and store it where you need it, sizing the basin to your acreage. Proper depth and a sealed bottom mean the water stays put until needed.

  • Recreational and Wildlife Ponds

    Some ponds are built purely for enjoyment. We design water features that suit fishing, swimming, or attracting wildlife, with varied depths and gentle shelves that support fish and plants. The finished pond becomes a lasting centerpiece that draws birds, frogs, and family alike.

  • Pond Cleaning and Restoration

    Older ponds fill with silt, weeds, and muck that choke the water. We drain, dredge, and reshape tired ponds, hauling out accumulated sediment and restoring lost depth. Cleaning brings back capacity and water quality, giving a neglected, silted pond a genuine second life.

  • Spillway and Overflow Management

    Every pond needs a safe path for excess water. We build spillways and overflow structures that carry heavy rain and snowmelt away without eroding the dam or banks. Managing overflow protects your investment and keeps a full pond from becoming a downstream washout.

  • Pond Bank Shaping and Grading

    The edges make or break a pond. We grade banks to stable slopes that resist collapse, control erosion, and blend into the surrounding land. Thoughtful shaping keeps sediment out of the water, makes access easier, and gives the whole pond a natural appearance.

Benefits of Pond Construction

A Dependable Water Source

Having water on site changes what your land can do. Livestock drink, gardens and fields get irrigated, and you hold a reserve for dry stretches. Instead of hauling or piping water in, you draw on a supply that sits exactly where needed most.

Improved Land Value

Value follows a thoughtfully placed, well planned working pond. It signals usable, well managed acreage that buyers notice, adding both function and appeal. For working and residential properties, a healthy pond can raise how much your land is worth and how it sells.

Habitat for Wildlife

Water draws life. Within a single season, a new pond attracts birds, frogs, dragonflies, and fish, turning a plain field into a small ecosystem. For families, it becomes a place to watch nature up close, and the land gains a richer, balanced environment.

Natural Stormwater Control

A pond does real work during heavy weather. By catching runoff from rain and snowmelt, it eases erosion, slows flooding, and keeps water from pooling where you do not want it. That control protects your driveways, structures, and lower ground across the property.

Low Maintenance Design

Built right, a pond mostly takes care of. Correct depth, stable banks, and a managed spillway keep the water healthy and the edges intact with little effort from you. Good design up front means fewer weeds, less muck, and years of easy enjoyment.

A Lasting Property Feature

Unlike features that fade, a well made pond only settles into the land over time. It anchors the look of your property, gives you a spot to gather, and holds its purpose for decades. This is the kind of improvement that quietly endures.

Frequently Asked Questions

  • Do I need a permit to build a pond on my property?

    Often, yes. Larger and deeper ponds require permits, and rules vary by county and by nearness to streams or wetlands. With 13 years of local work, Bohlander Construction helps property owners in Corvallis, Montana understand what applies and plans the pond around it.

  • How deep should a pond be?

    It depends on purpose. Stock and recreation ponds often run six to twelve feet or deeper so the water stays cool, resists freezing solid, and discourages excess weed growth. We set depth, shelves, and slopes around how you plan to use the water.

  • What kind of soil holds water for a pond?

    Clay is the key. Soil with at least 20 to 30 percent clay content compacts into a natural seal that holds water. Sandy or gravelly ground leaks, so those sites need an added clay layer or a liner to keep the pond full.

  • What is the best time of year to build a pond?

    Late summer and early fall are usually ideal. The water table sits lower and the ground is drier, which makes digging and shaping cleaner and easier. so, we can plan pond work around your schedule and site conditions through much of the year.

  • How long does it take to build a pond?

    Timelines vary with size, soil, and access. A modest stock pond may take several days, while a large or engineered pond runs a couple of weeks or more. We assess your site first and give you a realistic schedule before any digging begins.

  • Why does my pond keep leaking?

    Most leaks trace back to soil. Without enough clay, or without a compacted core, water seeps through the bottom and banks. Bohlander Construction diagnoses leaks on ponds around Corvallis, Montana and reseals them with compacted clay, a core trench, or bentonite as needed.

  • Can one pond be used for both livestock and irrigation?

    Yes. A single well sized pond can water cattle and feed an irrigation draw, as long as depth and capacity match the combined demand. We plan the basin and banks so animals reach the water safely without fouling the supply you pump out.

  • What makes pond water turn green or unhealthy?

    Green water means algae, fed by shallow depth, warm sun, and nutrient runoff. Adequate depth, aeration, and buffer plants around the edges keep water clearer and healthier. Building the pond correctly from the start prevents many problems that plague shallow basins over time.
