Hjälmaren in the context of "Mälaren"

Örebro (/ˌɜːrəˈbruː/ UR-ə-BROO; Swedish: [œrɛˈbruː] ) is the seventh-largest city in Sweden, the seat of Örebro Municipality, and capital of Örebro County. It is situated by the Närke Plain, near the lake Hjälmaren, a few kilometers inland along the small river Svartån, and has a population of approximately 126,000 in the city proper. It is one of the largest inland hubs of the country, and a major logistic and commercial operating site.

Örebro is home to Örebro University, a major university hospital, a medieval castle, the water park Gustavsvik as well as several large shopping malls and the Oset and Rynningeviken Nature Reserve adjacent to lake Hjälmaren.

Svartån is a river in Örebro County, Sweden, approximately 100 kilometers long with a drainage basin area of 1410 km. The river has its source at lake Ölen in Degerfors Municipality and flows south through the lakes Storbjörken and Lillbjörken and the mill town of Svartå. At lake Toften it joins with several streams from the south, flowing through Hasselfors to lake Teen, joining with Stavån. From Teen the river flows northeast over the Närke plain to the city of Örebro, passing Örebro Canal on its way east. East of Örebro the river passes through Skebäck and Oset, joining with Lillån before ending in Lake Hjälmaren.

Svartån is the main tributary of Lake Hjälmaren and Eskilstunaån, which in turn is the largest tributary of Lake Mälaren and Norrström in Stockholm, the main outlet into the Baltic Sea.

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.

Södermanland County (Swedish: Södermanlands län, [ˈsøːdɛrmanland lɛːn]) is a county or län on the southeast coast of Sweden. In the local Sörmlandic dialects it is virtually universally shortened and pronounced as Sörmlands län, or simply Sörmland, which is the dominant pronunciation and spelling inside the county. For example, the name of the local regional council is Region Sörmland. Södermanland's capital is Nyköping and the largest settlement is Eskilstuna. In the sparsely populated interior, Katrineholm is the largest locality. In total, Södermanland has nine municipalities and about 300,000 inhabitants.

Södermanland borders the counties of Östergötland, Örebro, Västmanland, Uppsala, Stockholm and to the Baltic Sea. It holds the popular camping route called "Sörmlandsleden" which is a system of trails covering a total of approximately 100 mil (1000 km) of walking paths in Södermanland. The county has shorelines on Sweden's third and fourth largest lakes of Mälaren and Hjälmaren. There are also numerous large lakes in the Nyköpingsån river system through the west and centre of the county.
