Råcksta Träsk
lake in Stockholm Municipality, Sweden

Råcksta Träsk (Swedish: "Råcksta Swamp") is a small lake in the western suburbs of Stockholm, Sweden. Notwithstanding its location in the vicinity of the Swedish capital and high levels of lead and copper, the lake is considered as an important breeding ground for frogs, of moderate interest to pleasure fishing, and of minor interest for birds. There are three other small lakes located nearby: Judarn, Kyrksjön, and Lillsjön.
Catchment area
The catchment area is mostly composed of forest and open terrain part of the Grimsta nature reserve, with several minor wetlands. 20 percent of the catchment area is composed of residential buildings and 10 per cent of roads. 300 metres downstream is a historical mill administrated by a society devoted to local culture and history (Vällingby hembygdsförening) with limited means to regulate the water level. West of the lake is a grass-grown peak composed of excavated material from the construction of the suburbs Vällingby and Hässelby. Several heavily trafficked roads and a metro track passes above ground through the catchment area. 7 hectares of the area is occupied by the Råcksta Crematorium and its cemetery.
The lake and the surrounding area is regarded as of great recreational value.

Why this record matters
The phrase “lake in Stockholm Municipality, Sweden” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q7348446. Authority coordinates are 59.352, 17.875. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
