Hydrographic network

The Swiss hydrographic network comprises all surface and subsurface rivers, streams and canals. Lakes are also included. Both natural and artificial water bodies are considered. The water bodies and their hydrological catchments serve as spatial references for literally any question, problem and project related to hydrology and water resources management.
