Dont contribute to the problem. During the summer camping in the inner river canyons is restricted. All of the Cub Creek area, and all of Jones Hole Creek except the established site at Ely Creek, are closed to camping. With the exception of the Green and Yampa rivers, never bathe or wash clothes or dishes in a water source. Carry at least 1 gallion of water per person per day in the summer.
Water is scarce in some areas of the park.
All untreated water should be considered polluted by the microscopic organism Giardia, which causes diarrhea, cramps, and other unpleasent symptons. The most certain method to treat water is to boil it for 3 to 5 minutes. Chemical disinfectants are not considered effective. Filtering systems must remove particles as small as one micron in diameter to be effective. Apple cores and orange peels do not add anything to the desert enviroment-they attract skunks and insects, and make wildlife into pests.
