ecology

Since 2010 Argenbuehl is the Valle Reyer pond on action program for the rehabilitation of Upper Swabian lakes involved. An important goal of this program is to reduce nutrient inputs in streams, lakes and ponds and thereby improve and maintain the condition of the water bodies.

The catchment area of ​​the lake is used to 50 percent each for forest and agriculture (grassland).
