On May 1, 2004, at 11 a.m., the flood column was presented on the banks of the Main, below the former “Schwanen” inn. On the initiative and preparatory work of Edgar Büttner, members of the historical association tried for more than ten years to determine historical flood levels, which are only very sparsely documented in Mainaschaff. The fact that the post at the entrance to the courtyard of the former "Happel", which had some high water marks, was removed at short notice during the last renovation work before it could be documented, of course made our work more difficult. Nevertheless, it was possible to establish fourteen old and new high water marks with sufficient accuracy, so that an informative selection of flood events from the past 200 years on our banks of the Main is available for a high water mark. In addition to the well-known high water mark of February 1909 in Mainaschaff and the From the information provided to the water management office from the old Stockstadt lock (1920, 1970 and 1982), we still have the mark from January 1995 recorded by Büttner and the description of the local chaplain Joseph Schmitt about the great flood of March 1845 ("...about 3 shoes on the ground floor .... and 8 shoes in the garden"), who lived at Schwanengasse 3 at the time. All of these floods are also recorded at Theoderichstor in Aschaffenburg, so that the average flood gradient between Mainaschaff and Aschaffenburg could be determined with this data and other flood marks could be transferred from there to here with some accuracy. The flood column, which was commissioned by the municipality of Mainaschaff from Made by Uhl & Jacobi, it is made of red sandstone, has a diameter of 60 cm and is about 3 m high. It stands on an approximately 25 cm high foundation base, the upper edge of which was concreted by the municipal building yard at exactly the height of 110.00 m above sea level. The engraved marks can be easily measured with a ruler, as can future flood levels. In the space between the stamps from 1882 and 1845 there is lettering and the municipal coat of arms. The engravings are alternately rotated by 30° from the front view to avoid overlaps and the lettering can be recognized from both sides as you approach.
