Dead Sea was once the saltiest body of water in the world. This however is not the case anymore. Global warming, and Middle Eastern climate changes have caused much of the salt that was in the water to evaporate or sediment out into the surrounding soil, leaving the water at about 82 percent of its former salinity.
This, coupled with the increased salt content of the Great Salt Lake over the course of the last ten years due to an increased flow of runoff water flowing into the Great Salt Lake and watershed-style irrigation stemming the various flows of tributaries, has led to a new leader in the "Great Salt Race" as we in the field like to call it. I hope this answers your question.
According to The Guinness Book of World Records, the lake that has the award for Saltiest lake is "Don Juan Pond in Wright Valley, Antarctica. Don Juan Pond in Wright Valley, Antarctica, is so salty that it remains liquid even at temperatures as low as -53C. The two common ways of expressing the saltiness of Don Juan Pond are in "parts per thousand" (g salt/1000g water) and "percentage weight of salt per water". At its saltiest, Don Juan Pond contains 671 parts per thousand salt, compared to 35 and 300 for the ocean and the Dead Sea respectively. The percentage of salt by weight is 40.2%, compared to 23.1% and 3.38% compared to the Dead Sea and the world's oceans respectively"

The Dead Sea is the saltiest. Average specific gravity is about 1.666 but normal sea water is between 1.18 and 1.24, but in the Red Sea it can be as high as 1.3. No fish live in the Dead Sea, but it has many species of bacteria. The reason for the sea being so salty is the evoporation rate, and the incursion of additional salts during the sporadic rains in the mountains. There are numerous salt lakes in Africa, China, and in the US but none are quite so salty because of heavier rain fall and a lower evaporation rate. In some areas, salt lakes drained into the ground and eventually the water dried up, leaving layers of salt...so salt mining is common in many areas. Because the water is so dense, it is virtually impossible to sink and during attempts to explore the bottom of the Dead Sea, the divers were encumbered with many heavy weights to overcome their buoyancy. Remember that salt does not evaporate, only the water and it is likely that if global warming continues, the density of the Dead Sea will increase. Try this....boil some water and add as much salt as will dissolve, after it cools, allow it to stand in a glass container and watch the salt leave the solution and coat the inside of the container and form clumps on the bottom...this is what takes place in the Dead Sea daily.

Dead Sea is one of the saltiest bodies of water on Earth with a salinity of about 30%. This is about 8.6 times greater than the average ocean salinity.

Dead Sea is also the lowest point in World at 418 metres (1,371 ft) below sea level. It is located on the border between the West Bank, Israel, and Jordan, and lies in the Jordan Rift Valley.

The mineral content of the Dead Sea is significantly different from that of ocean water, consisting of approximately 53% magnesium chloride, 37% potassium chloride and 8% sodium chloride (common salt) with the remainder comprised of various trace elements.

The concentration of sulfate, SO42-, ions is very low, and the bromide ion concentration is the highest of all waters on Earth. Chlorides neutralize most of the calcium ions in the Dead Sea and its surroundings. While in other seas sodium chloride is 97% of the salts, in the Dead Sea the quantity of NaCl is only 12-18%.

Comparison between the chemical composition of the Dead Sea to other lakes and oceans show that the salt concentration in the Dead Sea is 31.5% (the salinity fluctuates somewhat). Because of its unusually high concentration of salt, anyone can easily float in the Dead Sea because of natural buoyancy as a result of the higher density of the water. In this aspect, the Dead Sea is similar to the Great Salt Lake in Utah, in the United States.

I believe the body of water with the highest degree of salt saturation is The Great Salt Lake of Utah, USA.

The Dead Sea
There is actually so much salt that it is almost impossible to sink.

The dead sea is the saltiest

The Dead Sea, I think.

just a guess -- Great Salt Lake. It makes sense because the salt there is so concentrated.
