Mysterious rising salinity of Lake Kineret

There is increasing alarm among Israel's water officials that the salinity of the Lake - Israel's main reservoir - is rising, even to the point that it will become too saline for drinking purposes. Historically, the lake's salinity varied and it is assumed that in the times of Petrus the fisherman, the lake was undrinkable and the fishing villages bordering the lake derived their water from springs.

The graph shows how salinity and water level are inversely related, that is, when the water is low, salinity increases. That is logical. Today the lake is very low, and therefore saline. It appears that the cause is NOT climate change, and the rainfall - within historical oscillations - has not decreased. So, it must be that the contributing rivers flowing in from hostile countries, as damming and overpumping, maybe to harm us or just because they are using the water for irrigation. That was the accepted view.

But no, inflow measurements at the border show no change. The Syrian Golan is depopulated because of their civil war. and Lebanon's agriculture is agonizing under the Hizballah. The conclusion must be that WE are extracting (stealing?) more water from the upper Jordan stream. But how could that be if our use of water is strictly regulated by the Water Authority (my former employer) and every drop is accounted for?  Everyone here knows the answer but the journalists.

I prefer to quote Sherlock Holmes. “When you have excluded the impossible, whatever remains, however improbable, must be the truth.”
