Lakemead Overlook in Las Vegas.

BOULDER CITY, NV (FOX5) -- The Lake Mead National Recreation Area is warning visitors to avoid swimming and contact with water at Princess Cove and North Arizona Telephone Cove on Lake Mohave, until further notice.

The waters exceeded local, state and National Park Service water quality standards for recreational activity, the National Park Service announced on Thursday afternoon. Biologists are re-sampling the water daily, and once levels return to acceptable levels, the advisory will be lifted.

Increases in bacterial levels like this are often caused when people dump RV or vessel sewage tanks in the water, the park service said.

Free dump stations are available at all park campgrounds. If a visitor sees or suspects illegal dumping, they are advised to call 9-1-1 immediately.
