The size of the catchment
Mariager Fjord 572 km² (red line).

Mariager Fjord is a highly eutrofic fiord with very high production of algaes, low secchi depth and extensive oxygen deficiency. The main problem of the fiord is eutrification due to the high loading of nitrogen and phosphorus from the catchment area. The agricultural losses of nutrients are very highly dependant on climate, and therefore climate changes will have a strong influence on losses. In general, we expect higher losses of nutrients if there are no changes in current agricultural practices. Farmers as water managers are essential for reaching good ecological status.
