This provides important areas of shade because much of the river is directly illuminated by the sun, something which leads to rapid weed growth and choking of the river bed. The river channel was formed, like the surrounding landscape, in the penultimate ice age , the Saale glaciation . The ice sheets shaped
24-434: A valley during the course of its existence which, in its middle reaches, is about 10 m deep and about 1,000 m wide in which a eutrophic peat fen has become established. In earlier times the valley was only used as grassland due to frequent flooding; today the river meadows are mainly used for arable farming.

The 2004 Lower Saxon water quality report assesses the chemical water pollution of the Kleine Aller as variable. The values for organic pollution, nitrate, ammonium and phosphate contamination vary from lightly polluted to very heavily polluted. Ammonium levels in particular suffer from wide variations and sometimes high values. This
