Water from the Warta and its tributaries was both one of the basic raw materials and an energy producer, via water mills, in the manufacturing processes of workshops or groups of craftsmen (tanners, shoe makers, wood workers, beer brewers) along its banks. While in the Middle Ages the river pattern of Poznań played an important role in the development of the city area, in the middle of the 17th century its significance began to gradually decline, ultimately disappearing. The Warta lost its significance as a water route. Its waters are polluted and it seems that the city has turned away from it.polinfo:eu-repo/semantics/openAccessWarta riverwater management in the cityArtykułhttps://doi.org/10.14746/bfg.2015.6.4
