The Dead Sea’s northern basin is exceptionally deep, but its surface level and maximum water depth change over time. This page no longer combines measurements from different dates. Use a dated hydrological source when an exact surface elevation, depth, or historical comparison is required.
The lakebed position is geologically fixed, while the water surface and maximum water depth vary over time. Exact figures must be tied to the same dated hydrological measurement.
Two Distinct Basins
The Dead Sea consists of two geologically distinct basins separated by the Lisan Peninsula. The northern basin holds all the deep water, reaching the maximum recorded depth. This basin receives inflow from the Jordan River and most mineral springs, maintaining conditions for the hypersaline ecosystem. The southern basin was once shallow, never exceeding about 6 meters in depth. Since the 1980s, this southern section has been entirely converted to industrial evaporation ponds operated by Dead Sea Works (Israel) and Arab Potash Company (Jordan) for mineral extraction.
How the Dead Sea Formed
The Dead Sea occupies part of the Dead Sea Transform, a tectonic boundary between the African and Arabian plates that has been pulling apart for approximately 20 million years. This rifting created the Great Rift Valley, a series of depressions extending from Lebanon through East Africa. The current lake basin began forming about 3 million years ago.
The immediate predecessor of today’s Dead Sea was Lake Lisan, which existed from about 70,000 to 12,000 years ago and was much larger than the current lake. As climate shifted, Lake Lisan evaporated down to the smaller, more concentrated Dead Sea, leaving behind the mineral-rich sediments that characterize the region.
The Dead Sea's water level has declined substantially. This page no longer publishes an unsourced 1930 baseline or a single annual rate; use a dated hydrological measurement.
The Shrinking Dead Sea
The Dead Sea is shrinking because inflow has been reduced while evaporation and industrial water use continue. Exact water levels, annual change, and surface area must be reported with a dated hydrological source. This page no longer combines unsourced historical and current figures.
Why It Is Called Earth's Lowest Point
The Dead Sea shoreline is the lowest exposed land surface on Earth. Its exact elevation changes as the water level changes, so use a dated hydrological measurement rather than an undated fixed figure.
FAQs
How deep can you swim in the Dead Sea?
Visitors do not actually swim in the Dead Sea. The extreme buoyancy means you cannot sink or dive beneath the surface. All visitor activity occurs in the relatively shallow nearshore areas where beaches provide access, typically in water less than 2 meters deep.
Is the Dead Sea below sea level?
Yes. The Dead Sea shoreline is the lowest exposed land surface on Earth. Its exact elevation changes over time and should be stated with a dated hydrological source.
How much has the Dead Sea shrunk?
The shoreline and water level have receded substantially, but this page no longer gives an unsourced 1930 surface-area baseline, total drop, or single annual rate. Use a dated hydrological measurement.
Will the Dead Sea disappear completely?
Scientists project the Dead Sea will stabilize before disappearing entirely, though at a much smaller size than today. As the lake shrinks, surface area decreases proportionally, reducing total evaporation. Eventually a new equilibrium should form, though potentially with the northern basin significantly reduced.
