After the years 1681, the spring disappeared at some point and was rediscovered in 1761. The Majesty of Denmark, Norway and Schleswig-Holstein was informed that a guard should be set up to maintain order here, as the number of people seeking help at the Gesundbrunnen was too great.

Important migration routes and waterways for the otter are the Elbe-Lübeck Canal, the Trave, the Schwartau and the Schwentine.

After a period in which the otter was almost extinct in Schleswig-Holstein, the species has re-established itself, particularly through immigration from Mecklenburg-Western Pomerania and Denmark.

Otters are once again increasingly found in Schleswig-Holstein and have experienced positive developments since the 1990s. Positive evidence has been found particularly in the western regions, such as the Stör River and its tributaries, as well as in the Westensee and Treene areas. The otter has also settled in the eastern regions, such as the island of Fehmarn.

The otter remains extremely rare in Schleswig-Holstein. Since 1988, no sightings have been made in the Eider-Treene-Sorge lowlands, one of the species' original main distribution areas in Schleswig-Holstein. This is hardly surprising: The legendary response of a "St. Peter's disciple" to a biologist's question in 1974 as to whether otters had been spotted on the upper Treene River: "Yes, there is one here, but we haven't caught it yet" (Anonymous 1974). Today, sightings are mainly from the southeast of the state, particularly the Schaalsee region, which connect to the much larger population in Mecklenburg-Western Pomerania. From here, individual otters have already reached the East Holstein Lake District. At the end of 2005, a specimen was even found dead on the edge of the Nordstrand peninsula, indicating the strong propensity of individual animals to migrate.

The otter remains extremely rare in Schleswig-Holstein. Since 1988, no sightings have been made in the Eider-Treene-Sorge lowlands, one of the species' original main distribution areas in Schleswig-Holstein.

Despite the positive development, otters continue to face considerable threats.

The Schaalsee region and the Schwentine with the adjacent lakes are important refuges for the otter.
