The Lonau is a 3.5 km long tributary of the Sieber in Lower Saxony .

course

It is created in Lonau by the confluence of the Great Lonau and the Little Lonau . Then it flows in a southerly (meanwhile in a south-southwestern) direction through the Lonau valley to Herzberg am Harz , where it flows into the Sieber after the Lonau waterfall .

On some maps, the Lonau (between the town of Lonau and Herzberg) is referred to as the Great Lonau . However, this contradicts the general usage of the local population, according to which the Kleine Lonau and the Große Lonau are the two source rivers of the Lonau .
