The loch where the Dorback Burn river originates is home to the ruins of what castle?
Lochindorb Castle
Lochindorb
Lochindorb (from the Scottish Gaelic: "Loch nan Doirb" meaning "loch of the minnows") is a freshwater loch north of Grantown on Spey in the Highland council area of Scotland.
 This loch is home to the ruins of Lochindorb Castle, a former stronghold of the Clan Comyn and is built on what now is said to be an artificially created island.
 It is also a popular spot with fishers and birdwatchers, the latter of whom come to see the local black-throated divers and greylag geese.
 At the southeast edge of the loch there is a small patch of coniferous forest.
Dorback Burn, Findhorn
The Dorback Burn (Scottish Gaelic: "Dorbag / Uisge Dhorbaig" ) is a right-bank tributary of the River Findhorn in northeast Scotland.
 It emerges from the northeast end of Lochindorb ( ) and flows northeast to a point where the A939 road and A940 road meet, where it is joined on its right by the Anaboard Burn.
 The Dorback then flows north, accompanied by the A940 for several miles until it is joined by the River Divie, which also enters from the right (east).
 Their combined waters flow on for a couple more miles to pass under the B9007 road and immediately enter the Findhorn ( ).
Pantabangan–Carranglan Watershed Forest Reserve
The Pantabangan–Carranglan Watershed Forest Reserve is a conservation area located in the upper reaches of the Pampanga River in Nueva Ecija, Philippines, and borders the Sierra Madre and Caraballo Mountains in Aurora and Nueva Vizcaya.
 It encompasses 84500 ha of the drainage basin surrounding the Pantabangan Lake, an impoundment of the Pampanga River by the Pantabangan Dam.
 The multi-purpose dam is situated at the confluence of Pampanga River's two headwaters, namely the Pantabangan and Carranglan Rivers in the municipality of Pantabangan.
 It stretches above the dam site for 21 km to where Carranglan River originates in the Caraballo on the north, and for 18 km to where Pantabangan River originates in the Sierra Madre on the east.
 It is considered a critical watershed for the agricultural economy and hydroelectric power generation in the region of Central Luzon. Loch Avich
Loch of Avich is a large freshwater loch that lies approximately 1 mi west of Loch Awe in Argyll and Bute in Scotland.
 It is the second biggest loch in the Etive basin after Loch Awe.
 It trends east-northeast, west-southwest and is narrowly triangular in shape.
 At the southwest end of the loch is the islet "Innis Luana" on which stands the ruins of an ancient castle named "Caisteal na Nighinn Ruaidhe" (Castle of the Red Haired Maiden).
 The castle may have been the original seat of Clan Campbell.
 Near the north shore on the islet of "Eilean Fraoch" is the remains of a crannog. River Nethy
The River Nethy (Scottish Gaelic: "Neithich / Abhainn Neithich" ) is a right bank tributary of the River Spey in northeast Scotland.
 It rises as the Garbh Allt between Cairn Gorm and A' Chòinneach on the northern slopes of the Cairngorms and flows northwards through Strath Nethy and into Abernethy Forest.
 Passing through Nethy Bridge where the B970 road crosses the river and gives its name to the village, the Nethy turns northwestward before entering the Spey at Broomhill.
 Numerous burns feed the Nethy, the most significant of which is the Dorback Burn which enters from its right bank a mile above Nethy Bridge. Satpura Range
The Satpura Range is a range of hills in central India.
 The range rises in eastern Gujarat state running east through the border of Maharashtra and Madhya Pradesh to the east till Chhattisgarh.
 The range parallels the Vindhya Range to the north, and these two east-west ranges divide Indian Subcontinent into the Indo-Gangetic plain of northern India and the Deccan Plateau of the south.
 The Narmada River originates from north-eastern end of Satpura and runs in the depression between the Satpura and Vindhya ranges, draining the northern slope of the Satpura range, running west towards the Arabian Sea.
 The Tapti River originates in the eastern-central part of Satpura, crossing the range in the center and running west at the range's southern slopes before meeting the Arabian Sea at Surat, draining the central and southern slopes of the range.
 The Godavari River and its tributaries drain the Deccan plateau, which lies south of the range, and the Mahanadi River drains the easternmost portion of the range.
 The Godavari and Mahanadi rivers flow into the Bay of Bengal.
 At its eastern end, the Satpura range meets the hills of the Chota Nagpur Plateau. Loch Brand
Loch Brand or Loch of Boghall was a loch situated in a depression between the Grange Estate, Crummock, Hill of Beith Castle site and Boghall in the Parish of Beith, North Ayrshire, Scotland.
 The loch was fed by the Grange Burn and surface runoff, such as from the old rig and furrows indicated by Roy's Maps of the mid 17th century.
 The loch was drained by the Boghall Burn that runs passed the 'Court Hill' and into Powgree Burn at Gateside. Krishnavati river
The Krishnavati river (Hindi: कृष्णावती नदी ), also called Kasaunti (Hindi: कसौंती नदी ), is a rain-fed river originates from Aravalli Range near Dariba copper mines in Rajsamand district of Rajasthan, and flows through Patan in Dausa district and Mothooka in Alwar district and then disappears in Mahendragarh district in Haryana where it use to be a tributary of Sahibi River, which in turn still is a tributary of Yamuna.
 Several Ochre Coloured Pottery culture sites (also identified as late Harappan phase of Indus Valley Civilisation culture) have been found along the banks of Krishnavati, Sahibi river, Dohan river (another tributary of Sahibi river originates near Neem Ka Thana in Alwar district) and Sota River (another tributaries of Sahibi river that merges with Sahibi at Behror in Alwar district).
 The drainage pattern for all these rivers is dendritic. Kosasthalaiyar River
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 . River Helmsdale
The River Helmsdale (sometimes known as the River Ullie) (Scottish Gaelic: "Ilidh / Abhainn Ilidh" ) is one of the major east-flowing rivers of Sutherland in the Highlands of Scotland.
 It flows broadly southeastwards from Loch Badanloch down the Strath of Kildonan (otherwise known as Strath Ullie), gathering the waters of the Bannock Burn on its left and the Abhainn na Frithe on its right before discharging into the Moray Firth on the North Sea at the town of Helmsdale.
 Other significant tributaries of the Helmsdale include the left-bank Suisgill Burn and the right-bank Craggie Water.
 Loch Achnamoine which is just over 1 km in length, lies on the line of the river 1 mi / 1.5 km downstream of Loch Badanloch.
 Loch Badanloch is one of a complex of three interconnecting lochs - the other two being Loch nan Clàr and Loch Rimsdale which gather waters from the moors on the southern edge of the Flow Country via the Allt an Lòin Tharsuinn, Allt Lòn a' Chùil and Rimsdale Burn.
