“Water in this area was ubiquitous and posed a considerable threat of flooding, especially during the spring thaw when the Beskid Mountain gullies and streams started overflowing. Moreover, only the development of a system of drainage ditches could make possible the acquisition of new land suitable for farming or any other investment. For these reasons, a large part of the planning work regarding the Interessengebiet involved identifying the directions of water flow, demarcating the locations of new ditches and dykes and filling up (also with human ashes) the meandering oxbow lakes of the Vistula.”
