Ronceva

The source of the Ronceva lies at 230 m above NN in the Wiehen between the hills of Heidbrink and Horsts Höhe at the lower end of the Mensinger Ravine. It flows initially to the east of the B 239 federal road on its way to the town of Lübbecke. The stream flows underground in the area of the town itself.
North of the town the Ronceva resurfaces before emptying into the Flöthe flows within Lübbecke's industrial estate, immediately next to the factory buildings of Gauselmann . The Ronceva has a length of around 5 km, of which about 1.5 km is piped underground.
The catchment area of the Ronceva covers around 4 km2, i.e. just 7% of the total area of the borough of Lübbecke.
In spite of its relatively short length the Ronceva flows through three markedly different landscapes: the Wiehen Hills, the Lübbecke Loessland and finally the Rahden-Diepenau Geest.
