                                       Waterway Markers
All official waterway markers (signs, buoys, lights, etc.) are designed to assist the boater by marking unsafe areas, directing traffic through safe channels, preventing accidents, and protecting resources. Honor them-they have been placed for your benefit.

Placement of all buoys or markers: It is unlawful to place any aids, markers or buoys on shore or in the waters of this state unless authorized by the political subdivision or municipality having jurisdiction. They in turn must obtain the necessary approvals from the Department of Natural Resources and any Federal Agencies concerned before the aid is placed.

                                     Channel Marker Buoys
All-green and all-red companion buoys indicate that the boating channel is between them. In flowing water, the red buoys is on the right side of the channel when facing upstream. The boating channel lies between these buoys.
All White Buoys with Black Vertical Strips-These buoys show the center of the channel and should be passed close to on either side.
Mooring-Buoys-These buoys shall be all white with a blue stripe mid-way between the top and the waterline. They will be spherical or ovate in shape with a minimum of 18 inches above the water-line. Authorization for placement shall be regulated the same as any other buoy, aid, or marker when placed more than 150 feet from shore.










                               Regulatory Buoy and Sign
Restriction. A white buoy or sign with an orange diamond and cross means that boats must keep out of the area. Black lettering on the buoy or sign gives the reason for the restriction, for example, SWIM AREA.
Danger. A white buoy or sign with an orange diamond warns boaters of danger-rocks, dams, rapids, etc. The source of danger will also be lettered in black. In winter, ice, hazards may also be identified with this marker in the form of a sign.
Controlled Area. A white buoy or sign with an orange circle indicates controlled or restricted areas on the water, such as slow, minimum-wake zones. Information on the specific restrictions will be lettered in black.
Informational. A white buoy or sign with an orange rectangle provides the boater with information or directions. Information will be in black.

                                Suggestions for Safety
1. Keep an alert lookout.
2. It is recommended that all occupants of any boat, or at least children and nonswimmers, wear an approved personal flotation device for their added safety.
3. Obey rules of the water.
4. If the boat tips but floats-stay with it.
5. Keep away from immediately above and below locks and dams, especially on the Mississippi River. Obey the U.S. Corps of Engineers signs.
6. Wisconsin weather has a habit of changing radically in a short period of time. These changes are almost always forecast well in advance by the weather bureau and warnings issued.

                          Make Wisconsin's Waters Safer
Report Boating Violations call your local law enforcement agent (warden, Sheriff, or police Department) or call 1-800-TIP-WDNR for Violations.

                    10 Most Common Boating Violations
1. Failure to provide proper number of personal flotation devices.
2. Operating boat without valid certificate of number,
3. Operating boat in prohibited area, in excess of speed limit on lakes 50 acres or less, or in excess of fixed limits.
4. Personal Watercraft violations.
5. Operating motorboat while under the influence of an intoxicant, or operating motorboat with BAC of 0.1% or greater.
6. Operating within 100 feet of dock, raft, pier, etc.
7. Operating boat at night without required lights.
8. Failure to display registration number or decal on boat.
9. Failure to secure or cover storage battery.
10. Failure to have certificate of number on board.

                        The Zebra Mussel- A Boaters Concern
The zebra mussel, a new invader to the Great Lakes, is about the size of a thumbnail. Zebra mussel can cause severe problems because they are very prolific and can attach in great numbers to any solid underwater surface. They are of special concern to boaters since they can encrust on boats hulls or cause damage to an engine.  Please take the following precautions when you transfer your boat from the zebra mussels infested waters of the Great Lakes or the Mississippi River to your favorite inland waters:

DRAIN all water from your boat, trailer, bilges, live wells, coolers, buckets, engine compartments or any other areas where water may be trapped. Even small amounts of water can hold zebra mussel larvae.
INSPECT your boat hull, prop, trailer or any other equipment and thoroughly scrape off any attached mussel. Young adults attached to boat hulls feel like grainy surface.
FLUSH your boat, trailer and any other equipment with hot tap water above 140 degrees F. Hotter temperatures in the range of 110 to 140 F are more effective for killing zebra mussels. An alternative to hot water treatment is to disinfect live wells or other areas where water is trapped using a household bleach solution (two tablespoons of bleach per gallon of hot water). Do not put this bleach water into the lake!
LEAVE your boat and/or equipment in a sunny location for at least 3 day before using it on inland waters. Adult zebra mussels, when deprived of a moist environment, should die. Outboard engines should be tipped up to allow cooling passages to thoroughly drain in order to prevent mussels from attaching. Another option is to flush the motor cooling system with hot water using special "Motor Muffs" available at your local marina.

For more information contact your nearest Wisconsin DNR field office.
