Catchments of German Surface Water Bodies

Abstract
A network of 26,570 water-body catchments in Germany was derived from the hydrologically-defined drainage basins of the German federal states. To these drainage basins, we assigned the longest intersecting or the next downstream water-body code. Spurious intersections were removed. As the official water bodies may be ecologically but not hydrologically well defined, we split them at confluences and intersections (extended water bodies). The dataset contains the local catchments of the extended water bodies which comprise at least one drainage basin. Drainage basins without assigned water-body codes were excluded. The total water-body catchments include the upstream local catchments and have to be derived from the network. The network file and the missing water-body codes are available as separate files.

Data Quality
The layer was derived from official datasets and inherits their geometric limitations like gaps and overlaps. 1. WasserBLIcK/BfG, Zuständige Behörden der Länder (2017). DRAINBASIN_DE, 31.03.2017.
