The catchment of the Erkensruhr River is situated in the Eifel and is mainly covered by spruce (Picea abies) and covers an area of 41.7 km². In total forest is covering 74 % of the catchment area. Settlements only represent less than 1 % of the area. The main soil types are Cambisol, Stagnosol, and Gleysols in the riparian zones. Soil texture is dominantly silty clay loam. The mean altitude is 526 m with an average slope of 32.1°. The annual air temperature and precipitation are about 7°C and 1080 mm, respectively. The Erkensruhr River is one tributary of the Rur water reservoir, which is used for drinking water purposes. More than 90 % of the Erkensruhr catchment is part of the National Park Eifel, who has started to change the spruce forest into a near-natural mixed forest. This measure has an influence on the hydrology of the catchment and the transport of matter (e.g. sediments, dissolved organic matter, nitrate etc.) .
