It is home to the longest river in the Czech Republic

One of the interesting facts about Prague is that it's home to the longest river in the Czech Republic. The Vltava River is not shared by any other country with the Czech Republic. The mainstream of the river originates on the Erná Mountain and empties into the Elbe River. The river was essential for trade, industry, irrigation, and water supply in the Middle Ages. Prague's development was greatly aided by the river. Nine dams have been built for water management and hydroelectric power generation since the river is prone to flooding. Prague tourism has also been made easier by the Vltava River.

The 28,090 square kilometers drainage basin of the Vltava river, which is 430.3 kilometers long, covers more than half of Bohemia and approximately a third of the overall land of the Czech Republic, making it the longest river in the Czech Republic. The river flows through Prague for 31 kilometers, passing through 18 bridges, notably the Charles Bridge. Up until 1912, when the Vinohrady Water Tower stopped pumping water, people drank from the river. It is, nevertheless, the source of drinking water if the elivka and Kárané sources' water supply fails or has to be repaired. The lengthy river segment upstream of the Podol facility is subject to tighter, second-degree pollution protection rules, and the Podol water processing plant is prepared for such situations.
