Regulations on rafts and docks

Temporary docks extending from shore generally require no permit. No permit is needed to install, construct, or reconstruct your dock on shoreline property
you own if you comply with the following:

• A dock is a narrow platform or structure extending toward the water from the
shoreline. A dock may provide access to moored watercraft or deeper water for
swimming, fishing, and other recreation.

• The structure, other than a watercraft lift or watercraft canopy, is not more than 8 feet wide and is not combined with other similar structures so as to create a larger structure.

• The dock is no longer than needed to achieve its intended use, including reaching navigable water depth.

• The structure is not a hazard to navigation, health, or safety.

• The structure will allow the free flow of water beneath it.

• The structure is not used or intended as a marina.

• The structure is consistent with the guidelines of the local unit of government.

• Docks placed on rock-filled cribs are located only on waters where the bed is
predominantly bedrock

Regulations for swimming rafts

However, structures such as swimming rafts cannot be placed in the water between sunset and sunrise without first obtaining a permit from the county sheriff.

All structures placed under a permit must have the permit number painted on them and either have a light visible in all directions or be reflectorized so as to reflect light from all directions.

Contact the water patrol unit of the St. Louis County sheriff’s department for permit information. Call the DNR Boat and Water Safety Section at 651-259-5400 for additional information.
