Laxá í Kjós
river in Höfuðborgarsvæðið and Vesturland, Iceland

Laxá í Kjós (Icelandic pronunciation: [ˈlaksˌauː iː ˈcʰouːs]; Laxá in Kjós) is a river in the Kjósarhreppur municipality of southwestern Iceland. It flows about 20 kilometres (12 mi) from the Stíflisdalsvatn [ˈstiplɪsˌtalsˌvahtn̥], a small lake northwest of the Þingvallavatn, into the Laxárvogur [ˈlaksˌaurˌvɔːɣʏr̥], a cove on the Hvalfjörður fjord.
It is known for its salmon fishing, particularly where the salmon must traverse up several waterfalls. Brown trout and sea trout are also caught in the river.
The first salmon hatchery in Iceland, established in 1884 by Danish scientist Arthur Feddersen in the village of Reynivellir, was stocked with 31 spawning salmon captured in the Laxá í Kjós and its main tributary, the Bugða [ˈpʏɣða]. Other tributaries include the smaller Svínadalsá [ˈsviːnaˌtalsˌauː], Hálsá [ˈhaulsˌauː], and Þverá [ˈθvɛːrˌauː], all of which flow into the upper section of the river below the Þórufoss.
Waterfalls
The Þórufoss [ˈθouːrʏˌfɔsː] is an 18 metres (59 ft) high waterfall, located about 1.5 kilometres (0.93 mi) downstream from where Laxá í Kjós flows out of the Stíflisdalsvatn. A further 6.5 kilometres (4.0 mi) downstream from the Þórufoss is the Pokafoss [ˈpʰɔːkaˌfɔsː] a rapids-like small waterfall with a 2 metres (6 ft 7 in) cascade. Both falls are accessible from the Kjósarskarðsvegur (Highway 48). Near where the river enters the Laxárvogur is another small waterfall, the Kvíslafoss [ˈkʰvistlaˌfɔsː].

Why this record matters
“Laxá í Kjós” is worth following because a concise public description often conceals a longer documentary argument. Here, Laxá, Kjós and river provides the most credible route into that argument.
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 Aug 4, 2026. The linked authority identifier is Q2772464. VIAF identifies the subject as 1517152140021811100008. Authority coordinates are 64.251, -21.345. 3 of 4 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1884.
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.
