It is quite a bit more salty than the ocean. It is VERY easy to float in due to displacement. This is from wikipedia: The Jordan, Weber, and Bear rivers (the three major tributaries) deposit around 1.1 million tons of minerals in the lake each year, and since water (but not the minerals) is constantly being evaporated, the concentration of minerals increases further.
That's a lot of salt and it is ever increasing. It is like North America's own dead sea.
It is used for boating (usually sailboats), though is very under used in my opinion. It is very shallow so that could be the reason behind it.
It?s pretty salty . It?s the closest thing we have to the Ocean though and you can get some good sailing in. Just stay away from the shore in the summer all the brine shrimp dry up on shore and it stinks!
