Historically, Eskilstunaån was of great importance for the economic development of the Rekarne region . The medieval town of Torshälla and the industrial town of Eskilstuna were both founded on Eskilstunaån. The river was canalized as early as the 17th century, but the canal became unusable a few decades later. Today's Eskilstuna och Torshälla canal dates from the 19th century. Nowadays the river and canal is only partially navigable with small tourist boats because of the many immovable bridges that have been built since the 1950s.
