The Alfsee was artificially created to regulate the water level of the Hase River and to facilitate agriculture in the Hase floodplains. This recreational lake is dammed by this dam. From here, you have a fantastic view of the large reservoir. Walking across the dam is definitely worth it.

Alfsee, located southeast of Alfhausen, a few hundred meters east of the B 68, can be reached from this federal highway and from the Neuenkirchen-Vörden junction of the A 1, which runs just to the east. Rieste train station, served hourly from Bremen (via Delmenhorst) and Osnabrück, is only about 1,800 meters from Alfsee.

The 330 m long overflow sill, the inlet of the Alfsee, was built in 1974 with a 10 hectare settling basin. This is where sand and alluvial particles that would worsen the water quality of the lake are supposed to settle. The outlet structure was also built in 1974.
