The lake is bounded by the Aarhus-Randers Rail Line to the west.

The catchment area is fairly small at just a few square kilometers so the inflow of phosphorus and nitrogen is relatively small compared to other lakes in Denmark but is still deemed too high and the surrounding agricultural areas would have to decrease runoff to the lake by some two kilograms annually to reach environmental targets.

Over time it may be necessary to undertake a restoration project to return the lake to its natural condition.

The factory caused major pollution with heavy metals in Geding Lake, Geding-Kasted Bog and the river Egå, in particularly with arsenic.

The factory has closed, the migration of heavy metals to waterbodies in the area has stopped and it is expected that the levels of arsenic will now decrease over time.
