 The village was largely dedicated to farming, although a stretch of the imperial post road connected it and Pfullendorf.A wide, flat plain, marshy in places, stretched between the base of the Pfullendorf heights and the village; low lying hills ringed the valley, which was creased by a small stream from which the village takes its name.Ostrach itself lies almost at the northern end of this plain, but slightly south of the Danube itself.
