Radunia

The Radunia ( _de. Radaune) is a small river in Pomerelia which issues from a lake and falls into the Motława (Mottlau) near Gdansk (Danzig).

A part of its water is conveyed into the city via the 13.5 km long "Radaunekanal" or "New Radaune" ["A Gazetteer of the World: Or, Dictionary of Geographical Knowledge, edited by Royal Geographical Society Great Britain, 1856", and "The Edinburgh Gazetteer, Or Geographical Dictionary, 1822" [http://books.google.com/books?lr=&q=Radaune+%22New+Radaune%22&btnG=Search+Books] ] or Radunia Channel ["The Radunia Channel is a historical canal constructed in the Middle Ages, in the XIV century, by the Teutonic Knights" - in Roumen Arsov, Jiri Marsalek, Evzen Zeman: Urban Water Management: Science, Technology, and Service Delivery, p. 117 (Scheme of hydrographical network in Gdansk) [8] [http://books.google.com/books?id=lF-SeWzru-AC&pg=PA117&dq=Radunia+canal+Teutonic&lr=&sig=SrMpENT-13nCDiAGzCnUbir2iK4] ] , a canal build in 14th century by Teutonic Knights, to provide water and power to operate the Great Mill (Große Mühle).

Its source is Jezioro Stężyckie (Radaune-See, Stendsitzer See) near Stężyca (Stendsitz). Near Krampitz, Radunia joins the Motława (Mottlau), a tribuatry to the Vistula in Danzig. Length is 103,2 km, area 837 km², with a height difference of 162 m. Places along the river are Żukowo (Zuckau) and Pruszcz Gdański (Praust), with 22,000 inhabitants.

From 1910 to 1937, eight water power stations were build, delivering 14 MW in total.
