Vah

Vah, written as Váh in Slovak and Vág in Hungarian, is a river in Slovakia. It is the longest river that flows entirely within the country and is one of the major watercourses in western and northern Slovakia.

Course and geography: The Váh has its sources in the northern part of Slovakia and runs generally southwest across the country. It passes through or near towns such as Žilina and collects numerous tributaries along its course, forming several reservoirs. The river ultimately drains into the Danube, making it part of the larger Danube river system. Its drainage basin covers a substantial area of western and northern Slovakia.

Hydrology and uses: The Váh hosts several hydroelectric facilities and reservoirs that regulate flow and generate electricity. The river and its surroundings support water supply, recreation, fishing, and tourism, and its valley serves as an important regional corridor for transport and development.

Etymology and names: The river is called Váh in Slovak, Vág in Hungarian, and has historical names in other languages such as Waag in German. The name is of Slavic origin and is linked to the notion of flowing water.

Overview: As a central river in Slovakia, the Váh plays a key role in the country’s hydrology, economy, and regional identity. It connects mountainous headwaters to the Danube basin and supports both infrastructure and ecological functions along its course.
