Kosasthalaiyar River, also known as "'Kortalaiyar" in Manali a distributary, is one of the three rivers that flow in the Chennai metropolitan area.
 The 136 km river originates near pallipet in thiruvallur District and drains into the Bay of Bengal.
 Its northern tributary Nagari river originates in Chitoor district of Andhra Pradesh and joins the main river in the back waters of Poondy dam.
 Its catchment area spreads in Vellore, Chitoor, North Arcot, Thiruvallur and Chennai districts.
 It has catchment area in North Arcot District with a branch near Kesavaram Anicut and flows to the city as Cooum River and the main Kosasthalaiyar River flows to Poondi reservoir.
 From Poondi reservoir, the river flows through Thiruvallur District, enters the Chennai metropolitan area, and joins the sea at Ennore creek.
 There are two check dams across the river at Tamaraipakkam and Vallur.
 The excess discharge in the river is controlled by the Tamarapakkam Anicut located across the river in the downstream of Poondi reservoir.
 Vallur Anicut is a small check dam constructed near Minjur across the river to control water levels and feed irrigation channels in the area.
 It flows to a distance of 16 km in the Chennai metropolitan area.
 The total catchment area of the river is 3757 km , and the bed width ranges from 150 to .
 The discharge capacity of the river is 110000 m3/s , and the anticipated flood discharge capacity is about 125000 m3/s .
The Terekty River (, Russian: река Теректы ), also known under the Sinified spelling Tielieketi (), is a small river that flows from China to Kazakhstan.
 In its lower course the river is also known as the Kusak (, Russian: Кусак , ).
 Along most of its course, the river flows through the very sparsely populated mountainous terrain of the southern part of Xinjiang's Yumin County; by the time it crosses the China–Kazakhstan border and enters a flat desert east of Lake Zhalanashkol, its bed is usually dry, with little water ever reaching Lake Zhalanashkol.
Taiga ( ; Russian: тайга́ ; ] ; from Turkic) also known as boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces and larches.
The Kazan River (Inuktitut "Harvaqtuuq", Inuktitut syllabics ᓴᕐᕙᖅᑑᖅ; meaning "strong rapids", "the big drift" or "place of much fast flowing water"), is a Canadian Heritage River located in Nunavut, Canada.
 The Dene name for the river was Kasba-tue meaning “white partridge river.”
 The name was apparently changed to Kazan in the late 19th century due to the influence of Order of Mary Immaculate missionaries.
 The river headwaters are in northern Saskatchewan at Kasba Lake, and it flows north for about 1000 km (621 mi) before emptying into Baker Lake ( ), on the opposite side of the mouth of the Thelon River.
 Along its course the river flows through several lakes, including Ennadai Lake and Yathkyed Lake, over the Kazan Falls (25 m ), down a red sandstone gorge and through both boreal forest and tundra.
 It is the last section of the river, below Ennadai Lake, that is above the timber line and is designated a Canadian Heritage River.
The Aropaoanui (Awapawanui) river flows from the Lake Tūtira to the Pacific Ocean in the Northern Hawkes Bay.
 It has been described as one of the cleanest rivers in New Zealand by the Department of Conservation, and is fished for many species including trout and whitebait.
 The valley and bay into which the river flows are also known as Aropaoanui, as is the metal road which meets the Napier–Wairoa highway.
The Khandeyar are one of the two groups of the Nenets.
 They are also known as Forest Nenets or Forest Yurak because they live in the forest region or Taiga instead of the Tundra like the other Nenets.
Todzha Lake, also known as Azas Lake (Russian: Тоджа, Азас ), is a lake in Tuva in Russia.
 The lake has a surface area of 51.6 km2 .
 The Azas River flows into and the Toora-Khem River flows out of Todzha Lake.
 The lake freezes in early November and remains icebound until the second half of May.
Lake Clementine (also known as North Fork Lake) is a reservoir on the North Fork American River Canyon above the picturesque gold rush era town of Auburn (elev.
 1200') in northern California.
 It was created in 1939 when the North Fork Dam, a 155 ft tall variable radius arch dam, was completed by the Army Corps of Engineers for the purpose of containing gold mining debris washing downriver.
 It is open to boat traffic, a waterskiing and wakeboarding spot during the summer.
 However, many days the lake is closed to wakeboarding so that the lake may be quietly enjoyed for kayaks, rowing, and fishing.
 It features steep forested canyon walls and contains several large high quality limestone deposits, one large vertical outcropping of which is known as Robbers Roost, and offers climbing and caving opportunities for the adventurous.
 A popular hiking, running, and mountain biking trail courses from the dam area, continues downstream below the 780' high Foresthill Bridge, linking Lake Clementine to the North and Middle Forks American River Confluence area below the dam.
 The trail also connects to a large-network of hiking, running, and mountain biking trail systems stretching eastward into the Sierra Nevada mountain range near Lake Tahoe.
 Because the dam is designed so that the river flows over its top, a waterfall is created that grows impressively large in winter and spring when rain and snowmelt cause high river flows.
The Routeburn River, also known as the Route Burn, is a river in New Zealand.
 It is a short stony river that flows for some 15 kilometres into the Dart River in the South Island.
 The Routeburn River flows alongside a section of the Routeburn Track.
 The upper reaches of the river are found in the Routeburn North Branch and leave the Routeburn Track around the Routeburn Flat Hut area.
The Marecchia (pronounced ] ) is a river in eastern Italy.
 In ancient times it was known as the "Ariminus" which was from the Greek "Ariminos", "Αρίμινος" (which is also the ancient name of Rimini).
 The source of the river is near Monte dei Frati which is east of Pieve Santo Stefano and southwest of Badia Tedalda in the province of Arezzo in Tuscany.
 It flows northeast into the province of Pesaro and Urbino in the Marche and is the only river that runs through Montefeltro.
 While flowing through Montefeltro, the river flows through the exclave Santa Sofia Marecchia, which belongs to Badia Tedalda.
 The river then flows past Sant'Agata Feltria and Novafeltria before crossing into the province of Rimini in Emilia–Romagna.
 At Torello, part of the commune of San Leo, it flows 1 km west of the Sammarinese territory Acquaviva and the San Marino River flows into it, but the Marecchia does not touch the San Marino border.
 Finally, the river flows past Verucchio and Santarcangelo di Romagna before flowing into the Adriatic Sea near Rimini.
