Supplementary notes In order to assess the potential input of toxic chemicals into Lake Kinneret, routine analyses of the Kinneret ecosystem have been carried out over the past 6 years.

Such compounds usually agricultural chemicals such as pesticides were extracted and analysed subsequently by gas chromatography. In general, lake water contained little if any pesticide residues, therefore further studies were carried out on samples from the Upper Galilee, close to the sites of application of these chemicals. These sources of pollution have now been largely reduced due, partially, to increased awareness of this problem through our monitoring programme.

Accidental and deliberate poisonings of fish continue to be one of the major problems in this field, although suspected cases have also dropped over in recent years.

In general, Kinneret St. Peter's fish Sarotherodon galileum has been largely effected by these chemicals usually the pesticides Endosulphan or Lindane. The combined use of more and more sophisticated agricultural chemicals and various combinations of them has caused increasing concern in our laboratory.

Our programme will therefore become of increasing importance in the near future. In Safed, for example, millimeters of rain were recorded, versus an average of mm. Rain that falls in Safed flows through the stream Nahal Amud into the Kinneret, which is just one source. In the last two winters, — and —, the water level rose by 6. It helps that in the summer of its level dropped at the most moderate rate ever measured since records began.

It is also crucial that water is barely being pumped from the lake any more for irrigation or drinking: Israelis are getting most of their potable water from desalination plants. At the southernmost end of the lake is Degania Dam, which feeds into the Jordan River. The dam was built in the s. In modern times, it is only opened when there is no choice because we lose water from the lake to the Jordan.

The last time it was opened was in which is a quarter-century ago. Then the Kinneret had reached 44 centimeters below the upper red line and the dam was opened for nine days. The big question is whether Degania Dam going to be opened again this year. Indeed the Jordan River has suffered. A century ago, the flow in the southern Jordan River was about 1. In , it was 97 percent lower, at just 40 million cubic meters. Almost all its water was diverted for drinking and irrigation.

In addition, towns along the river — Jordanian, Israeli and Palestinian — all dumped partially treated or raw waste into the water. In dry years, when the low level is reached, pumping is stopped.

In contrast, in rainy years, when the high level is reached the Deganyah dam is opened. Growing Syrian aggressiveness attempts at setting up military positions on Israel territory near Ein Gev and in the Chorazin area, harassing of Israel fishermen, etc.

The settlements around the Kinneret are mainly rural, while Tiberias serves as the urban center of the region. In the population of the Kinneret region was 96, Schmorak, Atlas Yisrael , V map 3; S. Yeivin and H. Hirschberg eds. Sources: Encyclopaedia Judaica. All Rights Reserved.
