Weed Rake

 

Many aquatic plant management and nuisance control activities require a permit issued by the department. Please contact your local aquatic plant management coordinator before engaging in any aquatic plant management or nuisance control activities. Permits are needed for aquatic plant control when chemicals are used, biological controls are used, physical techniques are used, or if wild rice is involved. Visit Aquatic plants for more information. Mechanical devices or plant barriers placed in public water on lake or stream bed or that impacts lake or stream bed may require a permit.

Do I Need a Permit?

This is a text link version of our weed rake interactive question and answer module. If you see this message, you currently have JavaScript disabled or are in compatibility mode while using Internet Explorer. This text version is here to help you understand if you need a permit from the Wisconsin Department of Natural Resources for your weed rake project, and if so, which one. Please go through and answer each question. This will help you determine which permit you will need.

Question 1 :

What do you want to do:

If your answer is "Place a device ATTACHED OR TETHERED TO AN EXISTING STRUCTURE LIKE A PIER OR PILING that is designed to remove aquatic plants mechanically,” go to Question 2.

If your answer is "Place a device THAT IS FREE FLOATING OR ANCHORED TO THE BOTTOM OF A LAKE OR STREAM that is designed to remove aquatic plants mechanically,” :

You've answered Place a device THAT IS FREE FLOATING OR ANCHORED TO THE BOTTOM OF A LAKE OR STREAM that is designed to remove aquatic plants mechanically:

Since you want to utilize a device that is NOT attached to an existing structure, but instead either free-floating or tethered to shore or a device directly anchored to lakebed or streambed, an individual permit is required. To apply for a Miscellaneous Structure individual permit, please visit the individual permits page.*Please note: WAMS ID and password are required to apply. If you do not have a WAMS ID, you must register for one before proceeding.

The department has developed a permit checklist [PDF] describing the information necessary to submit a complete application. Please review this checklist before applying to ensure you have all of the necessary information.

You've answered I don't know.

If your answer is “I don't know,”:

Drawing 1 depicts a device that is attached to an existing structure. If your device looks like this, go back and choose"attached to the existing structure."

Drawing 2 depicts a device that is free-floating or anchored to the bottom. If your device looks like this, go back and choose"free-floating."

Question 2 :

How does your device mechanically remove aquatic plants? Does it:

If your answer is "Have a FLOATING boom that removes plants by the movement of rake tines WITHOUT grubbing, lifting or rolling of the bottom sediments,” go to Question 3.

If your answer is "Place a device THAT IS FREE FLOATING OR ANCHORED TO THE BOTTOM OF A LAKE OR STREAM that is designed to remove aquatic plants mechanically,” :

You've answered I don’t know how my device removes plants.

If your answer is “I don’t know how my device removes plants,”:

Drawing 1 depicts a device that has a non-floating boom and rolls along the bottom to control plants. If this most closely resembles how your device operates, please go back and choose"non-floating boom."

Drawing 2 depicts a device that has a floating boom and uses hanging tines to remove vegetation without rolling bottom sediments. If this most closely resembles how your device operates, go back and choose"floating boom."

Question 3 :

Based on the answers to your previous questions, it appears that your device can be considered a weed rake*. Will your device be placed in a water body designated as an area of special natural resource interest (ASNRI), OR within a public rights feature (PRF) as described in s. NR 1.06, OR located within a floating bog?

*A weed rake is a device that attaches to an existing structure such as a pier or piling, designed to mechanically remove aquatic plants by the movement of rake tines attached to a floating boom without grubbing, lifting or rolling of the bottom sediments.

You've answered Yes.

If your answer is “Yes,”:

To apply for a Miscellaneous Structure individual permit, please visit the individual permits page.*Please note: WAMS ID and password are required to apply. If you do not have a WAMS ID, you must register for one before proceeding.

Please apply for a Weed Rake General permit. *Please note: WAMS ID and password are required to apply. If you do not have a WAMS ID, you must register for one before proceeding.

Please also be aware there are additional General Permit standards:

  • boom radius may not exceed 24 feet in length and may not disturb bottom sediments in water depths greater than 3 feet.
  • the weed rake may not be operated unattended for more than five days of continuous operation.
  • vegetation that has been cut or dislodged must be removed from the waterway.
  • the operation may not result in the disturbance or removal of more than 1,200 square feet of vegetation.

The department has developed a weed rake general permit checklist [PDF] describing the information necessary to submit a complete application. Please review this checklist before applying to ensure you have all of the necessary information.

You've answered I don't know.

If your answer is “I don't know,”:

Please use our Surface Water Data Viewer - Designated Waters to find your location and to determine what the water body designation is for the water body where your project is located. Once you know this information, you may return toQuestion 3 and answer Yes or NO. (If you are unsure about using the Designated Waters Search tool, visit our tutorial to learn how.)
