The Lonau is a roughly 3.5 km long (from Lonau) tributary of the Sieber. It starts in Lonau, formed by the confluence of the Große and Kleine Lonau. It then flows in a southerly (intermittently in a south-southwesterly) direction to Herzberg am Harz, where it discharges into the Sieber after the Lonau Waterfall.
