Dead Sea water levels have been dropping since 1960. Currently, the waters recede about a meter per year, with about a third of its surface area evaporating into the air. The recession is evident in aerial photos of the lake, which demonstrate how significant the water loss is and will continue to be.

Because of the abundant algae and halophiles, as well as the high salinity, the lake does not support fish — but it teems with brine shrimp and brine flies, which provide essential nutrition for migrating birds.

The Great Salt Lake is home to many important biological and wildlife species, from archaea, to bacteria, to phytoplankton (400+ species). Perhaps the three most apparent species that can be seen with the naked eye are brine shrimp (tons), brine flies (billions) and birds (millions).

Fact: You can – and you should. Pads might not be the best option, since they'll absorb water till they're soaked, and could get weighed down or fall out. Plus, they might be visible through your bathing suit. On the other hand, tampons are convenient and safe to use in water.

You can't walk on the water of the Dead Sea. The water is rich in salt and minerals, so it has a silky, thick consistency that will keep you afloat if you're swimming. But the buoyancy is not enough to walk on. You can, however, walk on large slabs of solid salt that form in the water, and along the shore.
