Odeleite River

Odeleite is a river located in the municipality of Castro Marim, Algarve, in Portugal. It originates in the mountains of the Serra do Caldeirao and flows through the municipalities Sao Bras de Alportel, Tavira, Alcoutim, Castro Marim in the district of Faro. Also, there is a water reservoir of the same name because of the dam created on the path of the river. Odeleite is a right tributary of the River Guadiana.

The Odeleite Dam was built on the River Odeleite. An aerial photograph showed that the reservoir is shaped like a blue dragon, a symbol of power, strength and good luck in Chinese culture, as well as being an emblem that was traditionally used by the emperors throughout history. This fact has attracted the attention of many visitors, who started to refer to it as the "River of the Blue Dragon".
