The level of the lake, Israel's largest water reservoir, now stands at 211.56 meters below sea level, two and 3/4 meters below its optimal level. Each ten centimeters (4 inches) of Kinneret height mean another 17 million cubic meters of water, or roughly 2.5% of the country’s annual consumer demand.
Ronen Wolfmann, Director-General of Israel's public water company Mekorot (lit., sources), reported this week that the company had carried out approximately 200 hours of cloud-seeding flight-hours this winter - some 60% more than average. Cloud-seeding is done during the rainy season, from November to April, when the meteorological conditions - clouds, wind direction, and cloud temperatures - are favorable. Cloud-seeding is done preferably over the Kineret, and also over the Mountain Aquifer.
Mekorot reports that cloud-seeding increases rainfall in the north by an annual average of 13%, or 60 million cubic meters. This works out to a cost of only 10 agorot (just over 2 cents) per cubic meter, a fraction of the cost of desalinated water.
