Surface water is all inland waters standing or flowing on the surface of the land and coastal waters, including the territorial sea. Surface water bodies are divided into flowing (rivers, streams, ditches, canals), stagnant (lakes, ponds) and coastal water bodies. To manage surface water bodies, they are divided into parts, i.e. clearly distinct water bodies, and their records are kept.
