Rosh HaAyin springs, also called the Yarkon springs are springs located at the foot of Tel Afek, in the Yarkon National Park which was established in the region that surrounds the springs. These springs are one of the water resources of the Yarkon River. Until the 20th century, the water of the Rosh HaAyin springs flew into the Yarkon River, but nowadays most of the water of the Rosh HaAyin springs is used in various irrigation projects and do not reach the Yarkon River.
