Moesa (river)

The Moesa is a river in the Swiss canton of Graubünden and the Italian region of Lombardy. It flows through the Moesa Valley (Misox) and is a right tributary of the Ticino River.

Geography:

The Moesa originates in the mountains near the San Bernardino Pass. It flows generally southward through a narrow, steep valley, passing through towns and villages such as San Bernardino, Mesocco, Lostallo, and Roveredo. Eventually, it crosses the border into Italy and joins the Ticino River near Bellinzona.

Hydrology:

The Moesa is a typical alpine river, characterized by a highly variable flow regime that is influenced by snowmelt and rainfall. Its water is generally cold and clear, though it can become turbid during periods of heavy precipitation.

Economic Significance:

Historically, the Moesa has been used for irrigation and powering mills. Today, its primary economic significance lies in hydroelectric power generation and tourism. The valley is a popular destination for hiking, cycling, and other outdoor activities.

Environmental Concerns:

The Moesa is subject to some environmental pressures, including water pollution from agriculture and settlements, as well as habitat fragmentation due to infrastructure development. Efforts are underway to protect and restore the river's ecological integrity.
