Location of the lower reaches of the Attawapiskat River

The Attawapiskat River is a river in the Kenora District in northern Ontario in Canada . It flows east from Attawapiskat Lake to James Bay .

course

The Attawapiskat River covers 748 km (from the top of Bow Lake) and has a drainage area of 50,500 km 2 .

The origin of the river is in Attawapiskat Lake at an altitude of 241  m . The lake's main tributaries are the Marten Drinking River , Otoskwin River, and Pineimuta River .

There are two drains from Attawapiskat Lake to the Attawapiskat River: a southern and a northern channel. The southern channel is referred to as the Attawapiskat River in the Atlas of Canada . The Northern Channel is referred to as the North Channel by the Atlas of Canada . This is easier to navigate for canoeists. The North Channel outflow from Attawapiskat Lake is at ⊙ and consists of two short streams that flow to Windsor Lake. The height of the river drops enormously along these two outflow channels. You leave the higher Canadian Shield to the flatter and marshy Hudson Bay lowland . After a series of rapids, the North Channel joins the Attawapiskat River (the southern channel) at ⊙ at an altitude of 210  m .

The river continues its course in an easterly direction. He makes an arc to the north near Pym Island at ⊙ at an altitude of 174  m . The Streatfeild River flows from the right at an altitude of 148  m . The outflow of McFaulds Lake flows from the left about 17 km further downstream at ⊙ at an altitude of 139  m . Further downstream, the river changes direction to the east. The Muketei River flows to the Attawapiskat River from the left at ⊙ at an altitude of 105  m , the Missisa River flows from the right 28 km further downstream at ⊙ at an altitude of 98  m .

The Lawashi Channel starts at ⊙ at a height of 30  m and merges with the Lawashi River at a point 8.5 km above the confluence with James Bay. The mouth of the Lawashi River is about 11 km southeast of the mouth of the Attawapiskat. After the Lawashi Channel junction, the main river flows in an easterly direction past the settlement of Attawapiskat 10 km above the estuary, and flows into James Bay at the level of Akimiski Strait opposite Akimiski Island .

geology

Less than 100 km from its mouth, the Attawapiskat has cut several spectacularly high limestone islands out of the surrounding rock, which canoeists call "birthday cakes". chat-a-wa-pis-shkag was what the local Indians called these formations, which were unique in the region. From this the current name of the river was derived. The Attawapiskat kimberlite field lies on the river.

economy

The Otoskwin / Attawapiskat River Provincial Park comprises parts of the river course between Attawapiskat Lake and a point above the confluence with the Muketei River.

The De Beers Victor Diamond Mine in the Attawapiskat kimberlite field about 90 km west of the Attawapiskat settlement has been in operation since June 26, 2008 . The mine is expected to produce 600,000 carats (120 kg) of diamonds annually .
