The Adlatok River is a river in the Canadian province of Newfoundland and Labrador . An alternative non-official name of the river is Ugjoktok River , whereby the name mostly only refers to the southern branch of the estuary.

River course

The Adlatok River rises in the center of the Labrador Peninsula on the provincial border with Québec not far from the source of the south-flowing Kanairiktok River . The Adlatok River initially flows north-northeast. It flows through the Ashuapun , a larger lake. Then the river makes a wide arc to the east. The drain of the dead straight 45 km long Harp Lake flows into the Adlatok River on the right. Just before reaching the east coast of Labrador, the river splits into two estuary arms. The southern branch of the river flows into the Udjuktok Bay after 12 km , the northern branch flows into the Adlatok Bay after 25 km , 42 km southwest of Hopedale . At river kilometer 209.2 there is a 3.7 m high waterfall that prevents fish from migrating into the upstream river system. Mistinippi Lake and Shapeiau , two larger lakes, are located south of the lower reaches within the catchment area of ​​the Adlatok River.
