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.
