footnotes =The Alster is a 53 km long right tributary of the riverElbe in NorthernGermany . It has its source nearHenstedt-Ulzburg in the village of Kisdorferwohld inSchleswig-Holstein , approximately 25km north ofHamburg . The Alster flows roughly southwards and reaches the Elbe in Hamburg, which was founded on its shore. In the centre of Hamburg the Alster has been dammed since 1190, originally to power a watermill. In 1235 a further dam was built for a second mill, which changed the form of the river to be like a lake. The Alster forms two artificial lakes within the city limits of Hamburg, the larger calledAußenalster (outer Alster) and the smallerBinnenalster (inner Alster). Today these lakes and the surrounding parks serve as an important recreational area in the heart of the city.External links
