The name River of Crocodiles dates as far back as the Third Crusade, during which the crocodiles devoured two knights who were bathing in the river.

Hydrology

The area of the basin and its tributaries is about 200 square kilometers, including the Taninim, Ada, Barkan, Alona and Mishmarot streams. Nahal Taninim is the cleanest of Israel's coastal rivers. Three waterways meet in Nahal Taninim: the natural stream, a Roman aqueduct extending from the Zabrin springs to Caesarea, and Mifale Menashe, the waterworks that collect surface runoff water and springwater, routing it into the subterranean water table.

Flora and fauna

The dense undergrowth and reeds along Nahal Taninim are home to many different birds, among them waterside warblers and other songbirds.
