Vänern in the context of "Mälaren"

Västergötland (Swedish: [ˈvɛ̂sːtɛrˌjøːtland] ), also known as West Gothland or the Latinized version Westrogothia in older literature, is one of the 25 traditional non-administrative provinces of Sweden (landskap in Swedish), situated in the southwest of Sweden.

Västergötland is home to Gothenburg, the second largest city in Sweden, which is situated along a short stretch of the Kattegat strait. The province is bordered by Bohuslän, Dalsland, Värmland, Närke, Östergötland, Småland and Halland, as well as the two largest Swedish lakes Vänern and Vättern. Victoria, Crown Princess of Sweden is Duchess of Västergötland.

Vättern (/ˈvɛtərn/ VET-ərn, Swedish: [ˈvɛ̌tːɛɳ]) is the second-largest lake in Sweden, after Vänern, and the sixth-largest lake in Europe. It is a long, finger-shaped body of fresh water in south central Sweden, to the southeast of Vänern, pointing at the tip of Scandinavia. Vättern is deep, containing roughly half as much water as Vänern even though it covers about a third as much area; its deepest point is 128 metres (420 ft) below sea level.

Vättern drains into Motala ström through Bråviken into the Baltic Sea, but since 1832 it has also had a downstream connection through the Göta Canal to Vänern and the Kattegat tributary of the Atlantic Ocean. The lake has plenty of sources from rivers and small lakes, with the highest located sources being near Nässjö on the South Swedish Highland near the southeastern shoreline.

Svealand (Swedish: [ˈsvêːaˌland] ), or Swealand, is the historical core region of Sweden. It is located in south-central Sweden and is one of the three historical lands of Sweden, bounded to the north by Norrland and to the south by Götaland. Deep forests, Tiveden, Tylöskog, and Kolmården, separated Svealand from Götaland. Historically, its inhabitants were called Svear, from which is derived the English 'Swedes'.

Svealand consists of the capital region Mälardalen in the east, Roslagen in the north-east, the former mining district Bergslagen in the center, and Dalarna and Värmland in the west. It includes an extensive archipelago of thousands of small islands in Södermanland and Uppland and has lakeshores on the four largest lakes in the country. In the interior, there are several ski resorts in the southern parts of the Scandinavian Mountains. Two large rivers run through Svealand. Klarälven originates in Norway and enters lake Vänern through Värmland, whereas Dalälven runs from Dalarna through the lake of Siljan. The other major river basins in Svealand are Norrström that runs up in Bergslagen through lakes Hjälmaren and Mälaren, along with Nyköpingsån that covers the post-glacial lake district of Södermanland. Svealand generally has a moderate continental climate with a gradual decline of precipitation and increase of temperatures moving eastwards as the elevation descends.

Lake Peipus (/ˈpeɪpʊs/; Estonian: Peipsi-Pihkva järv, IPA: [ˈpei̯psʲi ˈpʲihkʋɑ ˈjærʋ]; Russian: Чудско-Псковское озеро or Псковско-Чудское озеро) is the largest trans-boundary lake in Europe, lying on the international border between Estonia and Russia.

The lake is the fifth-largest in Europe after Lake Ladoga and Lake Onega (in Russia), Lake Vänern (in Sweden), and Lake Saimaa (in Finland).

The Göta älv (Swedish pronunciation: [ˈjø̌ːta ˈɛlv]; "River of (the) Geats") is a river that drains lake Vänern into the Kattegat, at the city of Gothenburg, on the western coast of Sweden. It was formed at the end of the last glaciation, as an outflow channel from the Baltic Ice Lake to the Atlantic Ocean and nowadays it has the largest drainage basin in Scandinavia.

The Göta älv is located in Götaland, with the river itself being a site of early Geatish settlement. Its length is 93 km (58 mi). The Bohus Fortress is located by the river at Kungälv. There the river splits into two, with the northern part being the Nordre älv and the southern part keeping the name Göta älv; the two arms of the river enclose the island of Hisingen.

Dalsland (Swedish pronunciation: [ˈdɑ̌ːlsland]) is a Swedish traditional province, or landskap, situated in Götaland in southern Sweden. Lying to the west of Lake Vänern, it is bordered by Värmland to the north, Västergötland to the southeast, Bohuslän to the west, and Norway to the northwest.

The province has a low population density of around 14 inhabitants/km and just one town of significant size: Åmål. The total population numbers 50,604. The uninhabited areas are characterized by dense forests in the northwestern uplands and lakes in the east, giving rise to the epithet, commonly used for Dalsland, of "Sweden's lake province".
