The Kalter Gang feeds on many groundwater sources in the area of the Mitterndorfer Senke, which are located in the municipal area of Ebreichsdorf right next to the Piesting. For this reason, the middle and upper reaches of the Piesting have often been erroneously referred to as the Kalter Gang.Neilreich, August (1846). Flora von Wien. Vienna: Beck'sche Universitätsbuchhandlung. p. xvi. Measurement results show, however, that the Kalter Gang is an independent body of water that is characterised by more even water temperatures (hence the name; ) and a higher magnesium sulphate content than the Piesting.Küpper, Heinrich (1954). "Geologie und Grundwasservorkommen im südlichen Wiener Becken". Jahrbuch der Geologischen Bundesanstalt, no. 97. pp. 183, 189 (Piesting), p. 192 (Kalter Gang).
