translate English to German: Limfjorden was first connected with the North sea on February 3 , 1825 when a flood pierced an opening, the so-called Agger Canal , in the north of a 13 km long and less than 1 km wide isthmus , the Agger Tange . This isthmus had until then linked Vendsyssel-Thy with the rest of Jutland .
Größte Stadt und wichtigster Hafen am Limfjord ist Aalborg .
