The river marks the divide between forest and farmland. The apparatus in the metal cage in the water on the left comprises an acidity sensor and a pipe connected to a nearby lime doser. If the water becomes too acidic (due to acid rain), limestone powder is automatically released into the river to help restore the natural balance and protect plants and wildlife.
