Over the years, a gravel bank between the Loisach and the Kochelsee was piled up due to wave action. To reconect the Altwasser to the Kochelsee the gravel was removed and the old river bed of the Loisach was restored. This allows fish to spawn and live in the old water again. 

After the river bank of the Lobach has been flattened in the llast years, there is hardly any vegetation left.

The Blausee is one of the few bog ponds in the Allgäu and is home to many rare species. Peat digging and ditches have changed the hydrology in the edge area of the pond so that it became threatened to dry out. In order to maintain the water level of the Blausee, to stop peat decomposition and to restore the habitat of many species, the landscape conservation association carried out extensive and technically complex construction measures between autumn 2017 and spring 2018 to hydrologically restore the bog.

In 1978 the BUND Naturschutz and in 2006 the bavarian state forests have blocked drainage ditches in order to rewet the Beitenmoos.

The Breitenmoos is a bog in the FFH area "Moore im Wirlinger Wald" which is still intact in large parts and is home to numerous highly endangered, highly specialized species. The footpath and cycle path on the former railroad line Kempten-Isny touches the Breitenmoos, among others. A deep ditch was once dug along the railroad embankment to drain the edge of the mire. In some places, deep erosion gullies have formed over decades, and it was only a matter of time before they also drained the intact Schlenken complex of the bog.

Between 1950 and 1970 the torrent Wengener Argen was regulated and two drop structures were implemented. 2005 the two drop structures were replaced with river bed ramps and the river bed was widened. 

The ecological situation of the Heubach is due to its canalization was quite bad. The water authority of Kempten restored the Heubauch as ecological compensation for the flood protection constructions on the Durach river. After the restoration the brook flows in a natural river bed with different widths and a curved course. Structural elements (e.g. root stocks) were implemented and woods were planted.  

In the 1920s and 1930s the originally strongly branched course of the Isar river between Bad Tölz and Lenggries was forced into a single, slightly curved riverbed. Cylindrical gabions and large hydraulich construction stones have been securing the banks. Due to these actions impiortant habitats for flora and fauna were lost. To restore these habitats the river bank protection and the cylindrical gabions were removed. This allows the Isar to widen naturally and new habitats can develop. Additonal depth erosion can be prevented by the new load budget. 

The Tiroler Achen is except from the area at Schleching highly regulated. The water authority Traunstein could acquire a riparian strip next to this area and remove the bank protection to allow a self-dynamic development of the river. 

In 2006 the BUND Naturschutz created 13 ponds on a former small clay pit between Fechsen and Balteratsried. This is a good example of how new habitats can be created on a drainage ditch with relatively little effort and without negatively affecting the drainage. Part of the water is directed over the newly created ponds and flows back into the ditch at the end.
