The catchment of the Kall River is typical for the low mountain ranges of the Eifel and covers an area of 19 km². The dominate landuse is grassland vegetation (45 %), which is dominated by ryegrass, particularly perennial ryegrass (Lolium perenne) and smooth meadow grass (Poa pratensis). The dominant soils are Cambisol, Stagnosol, as well as raised bogs. The mean altitude is 532 m with an average slope of 17.3°. The annual air temperature and precipitation is about 7°C and 1200 mm, respectively. The Kall River drains into the Kall water reservoir, which is used for drinking water purposes. During the last decade the concentration of dissolved organic matter in the Kall River has increased, possibly caused by climate change due the increase of soil temperatures.
