The Kinneret is now 32 cm below the upper red line threshold whichmarks 208.8 meters below sea level. The sea is currently at the highest level it's been since 2004.
If the lake exceeds the upper red line threshold, the Degania Dam will be opened and the water will be diverted to the Jordan River.
The last time the dam was opened was in 2013.
Earlier this month, the Water Authority announced that the dam was not expected to open this year, even though the last two years have had high amounts of rainfall. In February, the Water Authority announced that it would open the dam in late March if the Kinneret reached 20 centimeters below the upper red line.
