Water bodies

Water bodies for both surface water and groundwater. A surface water body is a delimited, significant volume of water (catchment area for rivers, surface area for lakes and coastal water), delimited by hydrography, water type, pressures, ecological status or potential and chemical status. A groundwater body is a delimited body that either produces at least 10 m³ per day or can supply at least 50 people.

The dataset is the basic geographic unit in the Norwegian water regulations, vannforskriften, and is central to integrated water management "from mountain to fjord". Each water body is classified with ecological and chemical status, environmental objectives and a risk assessment for meeting the requirements of the EU Water Framework Directive. For a developer, the dataset is relevant for building near watercourses, assessing environmental impacts and applications that require an assessment under vannforskriften. Distributed by Norges vassdrags- og energidirektorat (NVE). Part of Placepoint's map layer for water. Related: Watercourses and catchments, Protected watercourses.
