Rječina

The Rječina (Italian: Eneo) is a river in Croatia that flows into the Adriatic Sea at the city of Rijeka (Fiume).

It is about 19 km long, with an average width of 9–16 m. It springs from the cave at a height of 325 m above sea level, below the high cliff of Kičej hill (606 m above sea level). Until 1870 the river's spring was below the next hill, Podjavorje, but it collapsed in an earthquake near the village of Klana. The most noticeable confluents are Sušica, Lužac, Zala, Zahumčica, Golubinka, Ričinica and Borovšćica, but they are dry for most of the year. In 1968 a dam was built to facilitate a hydroelectric power plant, creating lake Valići but destroying the village of the same name. Rječina flows through the canyon for almost half of her length. In Rijeka, the river branches into two parts: Mrtvi canal (the old basin), and the new canal, which was built in the 19th century when Mrtvi canal was used as a harbour. The most well-known sight is Gaspar's watermill (Gašparov mlin) in Martinovo Selo which was renewed in the 90s. Notable fauna are trout and river crabs.
