Abstract

Hydrologic data for the Dead Sea area were reviewed to assess the probable magnitude and rate of change of the water level of the Sea. Historical average annual Dead Sea levels range from a minimum of 399.4 meters below sea level in about 1818 to a maximum of 388.6 meters below in 1896. Present levels are rapidly approaching the historical low. There is a close correlation between Dead Sea level and accumulated departure from the mean of long-term rainfall except for the most recent period since 1964. During that period rainfall has been near the long-term average but water levels have continued to decline, in part due to abstractions for irrigation in the Jordan River basin. The dissolved-solids concentration of Dead Sea water presently is approximately 322,000 milligrams per liter and is generally well mixed. The increase in dissolved solids to the present high concentration has resulted in an evaporation rate less than that estimated in previous reports. An average annual inflow to the Sea of 900 cubic hectometers from all sources is required to stabilize the Sea at the present level. (Woodard-USGS)
