Having passed through the middle of the village of Buntenbock, the Innerste passes "Prinzenteich" and turns to the west to Wildemann (390 m), one of the smallest towns in Germany. Grumbach, one of the first tributaries, flows into the Innerste in the middle of Wildemann. The Innerste turns to the North to Lautenthal (300 m), another town on its course and flows parallel to the abandoned track of the Innerste Valley Railway. Here the Laute flows into the Innerste in the middle of Lautenthal. The name of the town means "Laute Valley". Near Lautenthal the Innerste is dammed (the "Innerstetalsperre"). When the dam was built 1963–1966, a nice lake for holidays and watersports was created. A few kilometers further on, the Innerste leaves the Harz Mountains near the town of Langelsheim (204 m) and turns to the Northwest. The first tributary is river Grane ( in length).
