Largest Lakes in Norway

Stora Le or Lesjön in Swedish and Store Le in Norwegian is a lake in Dalsland, Sweden, the northern end of which proceeds into Norway and into Värmland, where it continues as Lake Foxen.

The lake stretches approximately 70 km (43.5 Mi) from Ed in the south past Nössemark to Töcksfors in the north, on Lake Foxen. It is a narrow lake, rarely measuring more than 2 to 3 km (1.2 to 1.9 mi) across, apart from a stretch forming part of Lake Foxen, where it reaches a full 5 km (3.1 mi). Stora Le and Lake Foxen combined cover 131 km2 (51 sq mi). This makes Stora Le the 19th largest lake in Sweden. Its greatest depth is 99 metres (325 ft) to the south of Västra Fågelvik in the Lake Foxen part.

The lake system's level has been controlled since 1945 when the level was raised by 6 dm (2 ft) to 102.1 m (335 ft) above sea level. Lake levels are allowed to vary within a 1 metre (3 ft 3 in) bandwidth. The maximum allowed outtake of water is 80 cubic metres (2,800 cu ft) per second. The lake is reachable by boat through the Dalsland Canal. The lake's shores are mountainous and the forest nearly grows down to the water line. Dalsland's provincial fish the fourhorn sculpin is also found in Stora Le.

Røsvatnet (Norwegian) or Reevhtse (Southern Sami) is a lake and reservoir in Hattfjelldal Municipality and Hemnes Municipality in Nordland county, Norway. It has been the site of human occupation since the Stone Age. Its area of 219 square kilometres (85 sq mi) makes it the second largest lake in Norway by surface area. Without the dam which has regulated the lake since 1957, it would be 190 square kilometres (73 sq mi) and the third largest lake in Norway. Its depth is 240 metres (790 ft), its volume is estimated at 15 cubic kilometres (3.6 cu mi), and its surface elevation is 374 metres (1,227 ft) above sea level.

Tyrifjorden (Lake Tyri) is a lake in Norway. It lies 40 kilometres (25 mi) northwest of Oslo and is the nation's fifth largest lake with an area of 138.56 km2. It has a volume of 13 km3, is 295 meters deep at its deepest, and lies 63 meters above sea level. The lake's primary source is the Begna river, which discharges into Tyrifjorden at Hønefoss where the river forms the waterfall of Hønefossen. Its primary outlet is at Vikersund near the lake's southwest corner, where Tyrifjorden discharges into the Drammenselva river.

Snåsavatnet (Urban East Norwegian: [ˈsnòːsɑˌvɑtnə]; English: Lake Snåsa) is Norway's sixth-largest lake. The 126-square-kilometre (49 sq mi) lake is located in Steinkjer Municipality and Snåsa Municipality in Trøndelag county, Norway. The villages of Følling and Sunnan lie at the southwestern end of the lake and the village of Snåsa lies at the northeastern end of the lake. European route E6 runs along the northern shore of the lake and the Nordland Line railway runs along the southern shore.

The lake is approximately 40 km (25 mi) long and on average about 3 km (1.9 mi) wide. The surface of the lake is only 22 m (72 ft) above sea level, and it reaches depths of up to 186 m (610 ft). Its deepest area reaches; 164 m (538 ft) below sea level. The lake was created by glacial erosion. As it is seen on a map, the lake looks like an extension of the Trondheim Fjord. The outlet is the river Byaelva, which empties into the Beitstadfjorden (an arm of the Trondheim Fjord) in the city of Steinkjer.

Aursunden is a lake in Røros Municipality in Trøndelag county, Norway. The village of Brekken lies along the eastern shore and the village of Glåmos lies along the western shore.

There are several inflows to the 46-square-kilometre (18 sq mi) lake including the lakes Rien, Riasten, and Bolagen. The outflow is regulated by a hydropower dam through which water passes into the river Glomma. The lake is about 22 kilometres (14 mi) long and about 5 kilometres (3.1 mi) wide. The deepest part of the lake reaches a depth of 52 metres (171 ft).

Aursunden is often cited as the source of the river Glomma, the longest and largest river in Norway. The actual headwaters are near Aursunden near the start of the Glommadal valley. The locals claim that the headwater of the Glomma river is Mustjønna, a tiny lake about 30 kilometres (19 mi) north of Aursunden.
