오스나브뤼크‬에서 가장 멋진 ‪20‬개의 천연기념물

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.

When you come out of the town: At the entrance to the Meyerhof in Oestringen, to the left are the meadows up to the Nette. On the right side it climbs quite steeply, somewhere along the way you will see the ruins of the Wittekindsburg.

The Hase flows through small gates into the Alfsee.

It's best to drive on top of the dike instead of on the small pavement below.

A quiet quiet spot on the Hase

Just above Gesmold, the Hase forms a bifurcation. Here, the Else branches off from the Hase, causing around 2/3 of its water to flow into the Weser river system. It is still not clear whether this branch was artificially created to supply more water to the watermills of Gesmold Castle. A great environmental education site has been developed at the bifurcation since 2000. And there is also more information at the Terra Tip Bifurcation. Bifurcation Day takes place here every year on the first Sunday in May. Cyclists, families and nature lovers meet for an exciting festival with environmental education activities, concerts and delicacies. The extensive pastures around this striking place are grazed extensively and serve as a refuge for meadow birds such as lapwings, skylarks and also grass frogs.
