The Renau is a 5.4 km long right tributary of the Negroes .

course

The Renau rises between the Kahler Asten and the northern Bremberg and then flows in a general north-westerly direction. At the Schafsbrücke, a little above the Jagdschloss Siedlinghausen , the Renau crosses the state road 742 from Rehsiepen to Siedlinghausen and shortly afterwards flows into the Neger. The Renautal has typical over-shaping by small ice age glaciers and is almost completely forested.

The source is only a few meters away from the Rhine-Weser watershed . At its mouth, the Renau is longer and richer in water than the Negroes, and this in turn is richer and longer than the Ruhr at its mouth south of Olsberg .

Economy and culture

A drinking water dam with a capacity of 18 million m³ was planned in the lower Renautal .

Almost the entire valley floor along the Renau and its tributaries includes the 98.37 hectare Gutmecke and Renau nature reserve , which is home to many plants and animal species that are on the Red List.
