ドナウ=リース周辺のおすすめ犬連れハイキング＆ウォーキング

•Construction began in October 2015 •Continuous trial operation from February 2017 •Inauguration in May 2017 •Length: 1,150 m •Located on the left bank of the river around the Bertoldsheim traction power plant on the Danube, overcoming a total elevation difference of up to 7.2 m •Construction costs: €2.85 million •Most complex technical-natural fishway to date in the German section of the Danube •33 kilometers of the river in the section between the Bittenbrunn Danube power plant and the Donauwörth power plant are fish-friendly Explanation of the information panel regarding the Bertoldsheim fishway diagram: The entry structure of the fishway (FAA) is located approximately 500 m below, and the exit structure approximately 150 m above, the power plant. The elevation difference between them is up to 7.20 m, depending on the water level. The Fish's Path Upstream An artificial island in the Danube creates an attracting current and shows the fish the way directly to the entrance (point 1). A 120-meter-long (2) rough channel with 20 naturally designed pools creates a 1.8-meter elevation difference that is passable. The rough channel is connected to the existing bypass (3), which already has the character of a floodplain stream with spawning grounds. As a natural fishway, it is used for fish migration over a distance of 700 meters and overcomes an elevation difference of 60 cm. With its rootstocks, loose gravel, and varied course, it is not only an optimal migration corridor but also an attractive habitat for fauna and flora. Fish find ideal spawning and refuge sites here. The adjoining rough channel basin pass (4), with a length of 210 meters and 39 naturally designed pools, creates a further 3.2-meter elevation difference that is passable for fish. The exit structure is a vertical slot pass (5) constructed using technical construction methods. In 21 staggered concrete basins, the fish can overcome the remaining height difference of up to 1.80 m to the Danube reservoir. The slot pass has six automatically controlled gates (6) to regulate the water flow into the FAA according to the reservoir height. The flow averages 500 liters per second (3.3 bathtubs filled with 150 liters each). A trough structure penetrates the dam and connects the fish ladder to the Danube. Here, the fish return to the Danube above the power plant (7). Fish ladders like this contribute significantly to river continuity, promote river ecology, and the genetic diversity of aquatic life.

One of many on this section of the trail...

It's one of the two huts located in the cross-country ski section. It offers a direct view of the pond (with a tree island), which you can walk around.

It's one of two huts located in the cross-country ski section. The pond is somewhat hidden during the lush vegetation season. Signs with the relevant information can be found near the trees.
