The three sources of the Jordan, the Hasbani, the Dan and the Banias, unite here. South of the Huleh Lake the Jordan flows through a narrow channel between outcrops of volcanic lava. This barrier causes the water to spread north of the lake, producing the largest area of swamps in the country. The soil of the swamps is composed of acid humus and thick layers of peat, which can serve for the improvement of soil and various industrial purposes after drainage of the area. The swamps are rich in fishes and serve as an asylum for wild boars, water fowl, etc. The drainage works now being carried out have the purpose of transforming it into an area for intensive agriculture. There is also a plan for the establishment of a small Reserve for preservation of the local flora and fauna.
