Night Boating: Not Recommended

For many years Glen Canyon National Recreation Area has maintained an Aids to Navigation (ATON) Program on Lake Powell. The ATON infrastructure includes red and green buoys, which mark the main river channel and indicate the safest routes for boat operators to navigate within. Given that lake levels fluctuate on a daily basis and during some years vary almost 100 vertical feet from winter to summer, the ATON program is not designed to mark hazards outside of these delineated areas, as they are ever changing. Therefore, the National Park Service does not recommend that boat operators attempt to navigate vessels before official sunrise or after sunset. Operators who choose to operate during these times are at an increased level of risk and subject themselves, fellow passengers and other boaters to accidents which can result in property damage, serious injury or death.

Boaters who find themselves in emergency situations, which may necessitate navigating at night, are reminded there are inherent risks associated and are encouraged to seriously weigh the benefit versus the risks involved. When operating they are strongly encouraged to utilize as many of the following tools as possible to help mitigate the risk involved: training and understanding of ATON, formal boating safety classes, topographic maps and technological devices. In addition to these tools, there is no substitute for area knowledge and experience obtained during day-light hours.

Boaters should keep in mind the National Park Service only initiates responses on Lake Powell between sunset and sunrise during emergency situations, which involve life safety.

New Firearms Regulations

DESTRUCTION OF ARCHEOLOGICAL SITES IS ILLEGAL.
To report disturbances, notify the National Park Service at visitor centers, ranger stations or marinas, or by dialing 1-800-227-7286.

Off Road Vehicle Use
Vehicles and bicycles are not permitted off -road at any location in the park, except for the designated ORV area at Lone Rock Beach. All vehicles must be licensed and street legal.

Lake Powell Pure - Now and Forever

It's the Law.
If you are camping within one quarter-mile of Lake Powell's shoreline, or more than 200 yards from a designated restroom facility, you are required to possess and utilize a human sanitation device (portable toilet) that does not use plastic bags to contain the waste. This waste may not be disposed of in the trash, but only at pumpout/dump stations located on the lake and at the marinas. As an alternative, you may use a commercial Waste Bag Containment System, that can be disposed of in the trash. Portable toilets and Waste Bag Systems are available at camping and fishing supply stores.

It doesn't work if you don't use it.
Some people may think that digging a hole in the sand behind a bush is good enough. However, the lake level fluctuates a great deal throughout the year, and the cat hole you dug months ago could be covered with water today, resulting in your human waste floating in the lake. So in order to keep Lake Powell Pure, having a portable toilet with you is not enough. It must be used. Before your trip to Lake Powell, learn the mechanics of your portable toilet and make sure everyone in your group uses it.

Don't dump your tank in the lake.
It is illegal to use a boat on Lake Powell that can discharge sewage overboard. If your boat has a Marine Sanitation Device capable of overboard sewage discharge, it must be completely disconnected from the discharge port, the holding tank must only be connected to a deck mounted pumpout fitting, and sewage holding tanks have all discharge outlets capped or plugged.

Compliance is easy.
With eight floating restrooms/dump stations, and six areas within Lake Powell's marinas, you are never too far from a place to empty your portable toilet. If you and everyone else uses their portable toilet properly, you will never have to worry about a smelly camp, tripping over something nasty in the middle of the night, or swimming in contaminated waters.

Let us help.
Each week during the summer, National Park Service scientists use a state-of-the-art water laboratory to test for Esherichia coli (E. coli) bacteria from water collected at many beaches on Lake Powell. E. coli has been shown in numerous studies to be the best indicator of fecal pollution in water and can directly relate to the risk of human illness from recreation contact. In 2004, there were no E. coli counts high enough to close any of Lake Powell's beaches. It is through this cooperation of everyone who visits the lake that we can all celebrate this success, and continue to keep Lake Powell Pure.

If high counts of E. coli bacteria are found, beaches will be marked by bright yellow buoys and signs as closed until the levels return to normal.
