Lake Hefer is an artificial reservoir created based on the fish breeding ponds of Kibbutz Ein a Horesh. The Alexander creek supplied water to the ponds. In the second half of the nineteenth century, the Alexander creek was the only transport artery for Hefer Valley. Rafts with watermelons were floated along the river. Watermelons were supplied to Egypt from a small bay near the village of Jisr El Zarqa.
Agmon Hefer is a small closed lake ecosystem in the centre of the country. Migratory birds stop here. At the specially arranged points along the park paths, you can watch and hear the noise of pelicans, the chirping of cranes, and even the high flights of storks. The best time to see the wonders of nature is dawn.
