Question: What areas were colonized in the continent that houses the body of water that the Tekeze River turns into?

<P0-S0> It flows about 805 km (500 mi) to the Nile in north-central Sudan, joining it at the city of Atbarah (). <P0-S1> The river's tributary, the Tekezé (Setit) River, is perhaps the true upper course of the Atbarah, as the Tekezé follows the longer course prior to the confluence of the two rivers (at 14° 10' N, 36° E) in northeastern Sudan. <P0-S2> The Atbarah River (; transliterated: Nahr 'Atbarah) in northeast Africa rises in northwest Ethiopia, approximately 50 km north of Lake Tana and 30 km west of Gondar. <P0-S3> The Atbarah is the last tributary of the Nile before it reaches the Mediterranean. <SEP> <P1-S0> The Tekezé River rises in the central Ethiopian Highlands near Mount Qachen within Lasta, from where it flows west, north, then west again, forming the westernmost border of Ethiopia and Eritrea from the confluence of the Tomsa with the Tekezé at to the tripoint between the two countries and Sudan at . <P1-S1> After entering northeastern Sudan at the tripoint it joins the Atbarah River, which is a tributary of the Nile. <P1-S2> The Tekezé is perhaps the true upper course of the Atbarah, as the former follows the longer course prior to the confluence of the two rivers. <SEP> <P2-S0> originating as the chilliwack river in washington's north cascades national park, the river begins at hannegan pass and flows north across the canada–united states border and into chilliwack lake. <P2-S1> the river flows through hells gorge, a deep, dangerous-to-access gorge just below the river's headwaters that is home of a waterfall that the river drops over. <P2-S2> the river picks up the little chilliwack river before crossing the border. <P2-S3> there is a large sandy beach located where the river enters the lake, a popular recreational area among locals. <P2-S4> the river exits the north end of the lake and flows generally west via the chilliwack river valley to emerge on the fraser lowland on the south side of the city of chilliwack. <P2-S5> at vedder crossing, the river is joined by the sweltzer river before flowing under a bridge at which its name changes to the vedder river, after which is flows west and north to join the sumas river just before that river's confluence with the fraser river at the northeast end of sumas mountain. <P2-S6> the river crosses the fraser floodplain from vedder crossing to its confluence with the sumas via the vedder canal, which prevents the river's considerable spring freshet from flooding the surrounding farmlands and towns, and which is part of the drainage system that turned sumas lake into sumas prairie. <SEP> <P3-S0> the north american river otter (lontra canadensis), also known as the northern river otter or the common otter, is a semiaquatic mammal endemic to the north american continent found in and along its waterways and coasts. <P3-S1> an adult river otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). <P3-S2> the river otter is protected and insulated by a thick, water - repellent coat of fur. <SEP> <P4-S0> In 1870, only 10 percent of Africa was under European control; by 1914 it had increased to almost 90 percent of the continent, with only Ethiopia (Abyssinia), the Dervish state (a portion of present - day Somalia) and Liberia still being independent. <P4-S1> The ``Scramble for Africa ''was the occupation, division, and colonisation of African territory by European powers during the period of New Imperialism, between 1881 and 1914. <P4-S2> It is also called the Partition of Africa and by some the Conquest of Africa.
