FAQ
GENERAL PERMITTING
Do I need a DNR permit for my waterway project?
It depends on the type of project. Most dredging projects and pea gravel applications require a Wisconsin DNR permit. Some projects — including certain sea wall repairs and shoreline restoration work — may not require a formal permit but must still be conducted within DNR guidelines. The best way to determine whether your project requires a permit is to describe your project to Waterway Permit Pros. We can tell you quickly whether a permit is needed and what the process involves.
How long does a Wisconsin DNR waterway permit take?
The timeline varies depending on the type of permit and the completeness of your application. A complete, accurately filed dredging permit application typically takes several months from submission to approval — the process includes endangered resource review, public notice, and DNR staff review. Pea gravel permit applications generally have a shorter timeline. Incomplete or incorrectly filed applications take significantly longer. Working with Waterway Permit Pros ensures your application is complete and correct the first time, which is the single most effective way to avoid unnecessary delays.
Can I file a Wisconsin waterway permit myself?
Yes, you can. But the DNR permit process requires specific documentation, correct forms, precise timing, and an understanding of what the reviewing agency needs to approve your application. Errors or omissions in a permit application can result in significant delays, requests for additional information, or denial. Most property owners who attempt to file DNR waterway permits without assistance end up either frustrated by the process or delayed because of filing errors. Waterway Permit Pros handles the full process efficiently and correctly.
What areas does Waterway Permit Pros serve?

DREDGING
What is involved in a Wisconsin dredging permit application?
A complete Wisconsin DNR dredging permit application typically includes sediment sampling results showing the quality of material to be dredged, an endangered resource review confirming the project area does not contain protected species or habitat, an NR347 filing, a public notice published in a local newspaper of general circulation, and documentation of downstream notification. Waterway Permit Pros manages every component of this process.
What is the difference between hydraulic dredging and mechanical dredging?
Hydraulic dredging uses a pump to suction sediment and move it as a slurry, which is typically deposited in an upland containment area. Mechanical dredging uses equipment such as a bucket or clamshell to physically remove sediment from the water. The choice of method depends on the project scope, the type of material being removed, site conditions, and available disposal areas. Waterway Permit Pros can help you understand which method is appropriate for your project.
How much does a dredging permit cost?
The cost of a Wisconsin DNR dredging permit varies depending on the scope of the project, the amount of material to be dredged, and any additional documentation required. Contact Waterway Permit Pros for a free consultation and a fee estimate based on your specific project.
SEDIMENT SAMPLING
Why is sediment sampling required for dredging?
The Wisconsin DNR requires sediment sampling before a dredging permit can be approved to ensure the material being removed does not contain contaminants that would cause harm if relocated. The test results determine where dredged material can be disposed of and may affect whether the permit is approved. Sediment sampling must be conducted and reported correctly to meet DNR requirements.
What happens if sediment sampling shows contamination?
If sediment test results show elevated levels of contaminants, the DNR will require that dredged material be handled and disposed of in specific ways to prevent environmental harm. This may affect the cost and logistics of your dredging project. Waterway Permit Pros helps you understand what your sediment results mean and what options are available if contamination is found.
PEA GRAVEL
What is a pea gravel blanket and why would I need one?
A pea gravel blanket is a layer of pea-sized gravel applied to the bottom of a lake or waterway to suppress aquatic weed growth by blocking the light and substrate that weeds need to establish. It is one of the most effective and commonly used methods of managing aquatic vegetation in Wisconsin lakes. A DNR permit is required to install a pea gravel blanket.
How large can a pea gravel application be?
The allowable size and location of a pea gravel application is determined by the DNR based on your property, the characteristics of the waterway, and applicable regulations. Contact Waterway Permit Pros to discuss what may be possible for your specific waterfront property.
SEA WALLS AND SHORELINE
Do I need a permit to repair my sea wall?
Most sea wall repair projects in Wisconsin do not require a DNR permit — provided the sea wall already exists and the repair is limited to restoring the existing structure using like-for-like materials. New sea wall construction or significant modifications are subject to more restrictive requirements. If you are unsure whether your project falls within the permitted scope of repairs, contact us for a free assessment.
What is DASH and how does it work?
DASH stands for Diver Assisted Suction Harvesting — a method of removing aquatic vegetation by hand, underwater, using a vacuum-like suction device. It is effective for targeted removal of invasive species and is less disruptive to the lake bottom than mechanical harvesting. Most companies providing DASH services handle their own DNR permit filings. If you have questions about DASH or need assistance evaluating a DASH contractor, Waterway Permit Pros can help.
PROJECT MANAGEMENT
What does Waterway Permit Pros' project management service include?
Full project management from Waterway Permit Pros includes handling all required DNR, county, and city permits, coordinating with contractors, reviewing bids and scopes of work, overseeing the project to ensure it is completed according to the contract and within DNR permit guidelines, and preparing and submitting DNR close-out paperwork when the project is complete. This service is designed for property owners and organizations who want a single, knowledgeable point of contact managing their project from beginning to end.
What is an in-person project evaluation and when should I get one?
An in-person project evaluation with Kelly is a pre-project site visit where she assesses your waterway, discusses your goals, explains what permits and processes may be required, and helps you understand what is actually possible for your property within DNR guidelines. This service is valuable for property owners who are in the planning stage and want expert input before committing to a project or a contractor. Contact Waterway Permit Pros to schedule an evaluation.
