The Christmas Flood of 1717 and the one on 15 February 1718 destroyed the dikes and flooded Neuenfelde, acreages in the Land of Wursten in which the convent had the major share. The dike reconstruction was a lengthy and costly effort for the convent and the other parties holding land in the area. In 1718 Sebastian von der Lieth donated Rtlr 600 for another place (thus 11), first given to his sister Lücke Judith von der Lieth.
