Expansion of the Sea of Galilee due to water level increase (2018-2020) detected by the VENµS satellite. Read more...
Images obtained by VENµS, looks to the shorelines of the Sea
of Galilee in September 2018 and April 2020.
At the beginning of winter 2018-19, the water level of the Sea
of Galilee was the 214.55 meters below sea level, 21 cm
above what is defined as a ‘Black Line’. This height was the lowest
ever measured. Below this level, operational problems, related to pumping water
from the lake to the National Water Carrier, are expected to occur. Low water
level accelerates the development of toxin cyanobacteria.
On the 20 April 2020, the level of the Sea of Galilee was the
-208.94 m. 14 cm below the ‘Upper Red Line’. This height is
the maximum level to avoid floods along the shores and damage to
engineering plants. Therefore, when water reaches this level, there
is a recommendation to open the Degania Dam for releasing water to the southern
The added water areas mainly observed in the Ginosar Valley on
the north-west side and in the Majrase – Betiha (Bethsaida) Valley on the north-north-east
of the lake. Also, the small island, east of the lake’s outlet, was flooded and
The rise of the water level during the last two winters has helped the ecological
stability and improved the quality of the water. Water salinity
dropped. The natural algae (Peridinium) bloomed, while the toxin
were processed in the VENµS Scientific Center, the Remote Sensing Laboratory,
Desert Research Institutes, Ben Gurion University.
