Before it was drained, the Hula served as the natural sedimentation basin of the Sea of Galilee against the sediment of the Jordan. Moreover, the peat land was discovered to be particularly problematic. There was no demand for the dried peat, and the organic material in it was inflammable and cause fires that lasted for months. If that was not sufficient, the dry peat tends to shrink and sink. From drainage until the beginning of the 1990s the peat land in the Hula subsided to a depth of more than three meters lower than its original height.
In 1994, KKL-JNF undertook to improve the situation. Its people deepened the original course of the Jordan in the Hula Valley and reflooded an area of 1,000 dunams. The water that reaches the lake stays in it for a time before it continues to the Sea of Galilee, and over time the organic materials that remain in it subside. Creating the lake is also good for nature conservation. Another significant body of water was added to the Hula, and is used by migratory birds. In the near future, KKL-JNF will flood another area in the Hula, which will serve as an additional barrier in order to maintain the quality of the water of the Sea of Galilee.
In the rehabilitation project, KKL-JNF has turned an area covering 75 square km. from an ecological hazard into an area in which a wide variety of plants and animals flourish and has turned the Hula Valley into a tourism center with birdwatching sites, canals filled with fish, recreation areas in nature, land animals and birds, which offers abundant opportunities for touring by car, by bike or on foot.
