Waterline axes

Not only watercourses but also other water lines are shown in this dataset. Watercourses are defined as surface waters flowing through their own channel permanently or for most of the year (§ 43 of the Water Act) and have a designated administrator. Other watercourses are other surface waters of a linear nature (which do not meet the definition of a watercourse) such as embankments, water transfers, bypasses, ditches, etc. Other watercourses are generally immediately adjacent to watercourses and form a continuously connected river network and do not have a designated administrator.

Data on watercourses and other water lines are maintained and updated by the state enterprises Elbe River Basin, Vltava River Basin, Ohře River Basin, Morava River Basin, Odra River Basin and the Forests of the Czech Republic within the framework of the so-called Central Water Line Register. It is a line representation based on the ZABAGED base and is gradually improved on both sides.

The waterline axis layer shows the official provisions of watercourses according to the law and is essential for administrative actions related to water management.
