リーステの天然記念物・トップ20

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.

As early as 1999, the western Hase dam in the Gehrde-Rüsfort area was moved back over a length of 1.4 km. Around ten years later, the Hase dam was moved over a length of 0.8 km on the east bank. The additional lowering of the ground level has led to the development of fresh grassland and reed zones that correspond with the groundwater. This also enables periodic flooding typical of floodplains. The revitalized Hase floodplains also offer additional retention space for future flood events. Various wet biotopes and pools were also created. By establishing flora that is suitable for the site, a natural floodplain landscape is created in which various birds, reptiles, amphibians, grasshoppers and dragonflies find suitable habitats.

The Hase is a 169.6 km long, eastern and orographically right tributary of the middle Ems in the Osnabrück district, the independent city of Osnabrück, the Cloppenburg district and the Emsland district (all in Lower Saxony) as well as the Steinfurt district (in North Rhine-Westphalia). Its catchment area is 3086 km²[2]. Near Gesmold, the Else branches off from the Hase in the artificially created Hase-Else bifurcation, whereby part of its water also flows into the Weser river system. Much further north, the Hase branches off into the Große Hase and Kleine Hase near Quakenbrück in an inland delta that begins there, the Hasedelta.

The Hase flows through small gates into the Alfsee.

The water of the Hase flows through the Alfsee.

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

The overflow threshold is passable and I recommend this kl. Detour because of the great view over the lake and the sound of the water.

Surprise at the summit cross, I would probably call it a hill cross. In the little box on the cross is the "Gipfelbuch", in which everyone can write their names. A great idea! The place on the Schmittenhöhe offers a few places to rest, especially benches. The way there is surrounded by wonderful nature. The forest is impressive and very mythical in some places.
