How Much Does it Cost to Dredge a Pond?
Whether you oversee waterbodies in a community association, on a golf course, a municipality, or a private property, you’ve likely noticed changes in your lake or pond year over year. It may seem cloudy or murkier, or perhaps it’s more prone to algae growth or flooding.
What Is Dredging?
Many lake and pond managers do not recognize the complex nature of their aquatic ecosystems. Our waterbodies are constantly changing and, in a sense, aging. Over the course of two to three decades, they begin filling in with sediment and debris due to both natural and man-made forces (just like a newly dug hole will eventually fill in).
How Do I Know If My Waterbody Needs Dredging?
Dredging projects are expensive, unsightly, and inconvenient, which can have rippling effects, particularly in HOAs, apartment complexes, and other communities. It is all too common for stakeholders to raise dues and fall short on other community upkeep efforts in order to fund a dredging project.
Types of Dredging
There are multiple types of dredging equipment available to accommodate various properties, environmental restrictions, budgets, and waterbody types—each with their own benefits and challenges.
Mechanical Dredging
During mechanical dredging projects, long-reach excavators, semi-trucks, and trailers are brought into the project zone to drain all water from the lake or pond and scoop out hundreds of pounds of muck. This style of dredging is impactful and allows full visibility while working around underwater drains and equipment
Hydraulic Dredging
During the hydraulic dredging process (also referred to as liquid dredging), water and materials are pumped through a specialized tube—much like a vacuum—to a holding tank where dredged materials are contained and filtered. As water trickles out, it is returned to the lake or pond via tubing.
Budget Considerations
The benefits of dredging are clear, but many stakeholders do not understand the various considerations that go into a price estimate and may underestimate how early they should begin budgeting for these projects. How much does pond dredging cost? Here are some of the top factors:
How much land do you need to dredge a lake?
The size of area you will need will depend on many factors with the number one being the lay of the land. Usually for every two acres of lake that you dredge, an average of three foot of sediment, you will need an acre of upland area to place the material.
What is the difference between a muck pump and a dredger?
The dredger needs to know this as sand is costlier to pump further, but easier to dewater; while muck pumps easy, but can be costly to dewater, particularly if the disposal area size is limited.

What is dredged in a lake?
In most lakes, what is being dredged is often referred to as “muck.”. This is generally a combination of silt, clay, and organics. There is also sometimes sand in the very end of the coves.
Is rock more expensive than sediment?
Rock is even more expensive and most often cost prohibitive. There should be a clear distinction if the dredger is expected to only remove sediment that has filled the lake since it was originally constructed, verses cut virgin ground that has never been excavated.
Do all lake associations have more mud than money?
One final thing to consider is that all lake associations have more mud than money. With the hydrographic survey, you can set your priorities based on a realistic budget that your association is willing to spend. You and all of your neighbors live on a lake for a reason. It is a lifestyle.
Is sand more expensive to pump than muck?
The dredger needs to know this as sand is more costly to pump further, but easier to dewater; while muck pumps easy, but can be costly to dewater, particularly if the disposal area size is limited. Hard packed sand, or hard pan clay bottom, are more difficult to cut, and therefore more expensive.
What is pneumatic dredging?
Pneumatic. The pneumatic dredging process will use air pressure to help pump the sediments out of the lake. When compared to the hydraulic process, the sediment derived will have a higher solid rate, meaning less area will be needed to help the sediment de-water.
Why do we dredging?
The term “dredging” refers to the process involving the aquatic excavation of water beds to remove sediments, pollutants, shellfish and other materials. This can be done for a number of reasons: it can deepen waterways, create harbors, channels, locks, docks and/or berths. Dredging is also essential in de-silting lakes and keeping river entrances ...
Why do we need to dredge a pond?

Why do we need dredged up organic matter?
Dredged up organic matter can often be used as valuable topsoil. This soil will help nourish the grass and other plants. It will also disperse quickly and evenly due to the high-water content.
How does suction dredge work?
Suction Dredging operates by a diver extracting silt and water together and pumping it to the desired location. The most cost-effective method involves pumping the material into a field and letting the water and sediment dissolve and be absorbed into the ground.
What is a hydro rake?
The hydro-rake is a floating barge upon which a backhoe is mounted with a digging bucket or rake. It is capable of removing accumulated muck in water as shallow as 18 inches. Hydro Raking a very efficient for removing aquatic vegetation and debris from pond and lake. Image: Solitude Lake Management.
What does it mean when a pond has too many emergent weeds?
If too many emergent pondweed growths are noticeable then it is a clear sign that the pond has lost its depth. Emergent pond plants are a clear sign of shallow depth. You can clearly see excessive aquatic weed growth in the shallow area. When the entire pond starts to grow more weed, it’s time to dredge it.
What is an organic sediment removal system?
Organic Sediment Removal System. High-volume suction pumps are used with a suction head to remove the bottom sediments. This not only removes the sediments, but also the toxic gases, nutrients, and foul odors caused by the decomposition of the organic sediments by anaerobic bacteria.
Why does my pond smell bad?
If you find your pond water smelling unpleasant, the harmful byproducts that create when organic matter decomposes have reached a critical level . There is likely a substance imbalance or build-up of waste causing the problem.
Environmental Impact of Dredging
Since dredging requires the removal of unwanted sediment at the expense of the water body’s wildlife, it poses a huge threat to the water body's health, shoreline, and landscape.
