After about 3 kilometres it discharges into the Osterbek river. The stream is also known locally as the ''Grenzbach'' ('border stream', as it forms the boundary between the Bramfeld and Barmbek-Nord quarters in Hamburg). It has a good water quality. In the 1980s the streambed was largely returned to a near-natural condition after it had previously largely degenerated into a concrete drainage ditch. Today the stream provides an outstanding habitat for many small animals. The process of renaturisation had not finished; since March 2005 NABU has run ''Project Eisvogel'' (''Eisvogel'' = 'kingfisher') especially to improve the water flow through the Seebek.<ref>{{cite web |title=Unser 'Projekt Eisvogel' an der Seebek: Ein Überblick |website=hamburg.nabu.de |language=de |url= https://hamburg.nabu.de/wir-ueber-uns/stadtteilgruppen/bramfeld-ohlsdorf-barmbek/appelhoff.html}}</ref>
Since 1959 ''Seebek'' has also been the name of a steamer on the Alster river.
