BOULDER CITY, Nev. — Two popular swimming areas on Lake Mohave have been placed under an advisory by the National Parks Service.

The parks service issued the advisory Friday for Princess Cove and North Arizona Telephone Cove after bacterial levels in water samples at both locations exceeded local, state and NPS standards for recreational activities.

Park biologists routinely sample water quality at the park’s swimming beaches to help reduce the risk of waterborne diseases. Visitors should avoid contact with these waters until further notice. Biologists are resampling the water daily, and once levels return to acceptable limits, the advisory will be lifted.

According to a news release from the Lake Mead National Recreation Area, which includes Lake Mohave and Lake Mead, increases in bacterial levels often are caused when people dump RV or vessel sewage tanks into the water. If a park visitor sees or suspects illegal dumping, they should call 911 immediately. Free dumping stations are available at all park campgrounds.
