Main catchment areas

Sweden's watercourses are divided into a large number of main catchment areas defined by SMHI (Swedish Meteorological and Hydrological Institute).

The map image of a part of Sweden shows examples of some of the main catchment areas' geographical distribution and their HARO codes.

Main catchment areas are catchment areas that affect Sweden, which open into the sea and which, when defined, had an area that was greater than 200 square kilometers.

SMHI gives them a HARO code and usually also its name. The name is based on the main watercourse that empties into the sea.
