KATHERINE LANDING, AZ – Water quality levels at Arizona’s Princess Cove on Lake Mohave have returned to normal after a closure imposed last week. The swim advisory at this location has been lifted.  

However, the North Arizona Telephone Cove swim advisory remains in place on Lake Mohave in Arizona. Bacterial levels are declining, but additional monitoring is required for public health and safety. 

Currently, there are no other swim advisories on Lake Mead or Lake Mohave.  

Last week, bacterial levels in water samples taken at Princess Cove and North Arizona Telephone Cove on Lake Mohave exceeded local, state and National Park Service standards for recreational activity.

Park biologists routinely sample water quality at the park’s swim beaches to help reduce the risk of waterborne diseases. 

Increases in bacterial levels like this are often caused when people dump RV or vessel sewage tanks in the water. If a visitor sees or suspects illegal dumping, they should call 911 immediately.

Free dump stations are available at all park campgrounds.
