Magelungsdiket
watercourse in Rågsved, southern Stockholm, Sweden
Magelungsdiket (Swedish: Magelungen Ditch) is one of three inflows of Lake Magelungen in southern Stockholm, Sweden. It empties into the lake from north together with Kräppladiket while Djupån reaches the southern end of the lake.
Magelungsdiket had a drainage area of 17 km2 stretching north to Mälarhöjden until the south-western suburbs of Stockholm were built in the early 1950s and water was guided to Lake Mälaren through stormwater pipes. Today only 1,5 km2 remains of the drainage area and most of the contributions comes from one-family houses in eastern Rågsved and green areas around Magelungen. Water flow is slow, often stagnant, and the ditch is surrounded by dense vegetation. It opened out in a wetland drained in 1994 in order to create canals and minor islands attracting birds. Very high levels of metals have been reported from a street inlet near the outlet. Together with Kräpplingadiket, it is estimated to contribute some 100 kg/year of phosphorus. The ditch is one of a few locales for Grass Snake in Stockholm.

This brief starts where responsible research should: with the source description of “Magelungsdiket” as watercourse in Rågsved, southern Stockholm, Sweden. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as watercourse in Rågsved, southern Stockholm, Sweden. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 20, 2025. The linked authority identifier is Q6730096. Authority coordinates are 59.251, 18.046. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1994 and 2000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
