Main catchment areas — main waters

Catchment areas are aboveground areas delimited by water sheaths, from which water flows above ground or underground to a specific place and can be detected there as a flow. For the main catchment areas only the catchment areas of the main waters are presented. Catchment areas of the entire water network are located in the layer of catchment areas. This database is improved annually, with a focus on improving the designation. Column description in your own spreadsheet!
