The name Orchy may be ancient, and derived from Brittonicare-cētia meaning "on-wood".
Geography
The Orchy rises in the Black Mount Forest where its waters within the Deer Forest include the Island Pool and the Elbow Pool. After a run of, in which it receives the waters of several large burns, it expands into Loch Tulla. Between Loch Tulla and Loch Awe, the river runs for. It passes through Glen Orchy in a narrow channel. At Dalmally Vale, the river spreads into wide shallows, accumulating on banks. At the point of a shingle island, the Orchy flows through a cultivated strath, about wide. The river merges with the waters of Loch Awe at Kilchurn Castle. with the River Orchy in foreground Above the Bridge of Orchy, the river water is shallow and stony. In the of the river before its falls, there are many angling streams and pools. At Bridge of Orchy, the river is accessible via the A82. The river's course changed in the mid 19th century. Prior to that, the river banks were protected, and the Orchy ran through Dalmally Vale through a narrow channel. As of 1884, the fields on the northern river bank extended farther south; and shingle island was a narrow strip of gravel with a small stream. When the banks were no longer protected, a large curve was cut away into an island, causing the river to extend farther and farther into the banks. Around 1900, a rough breakwater was built, diverting the current, and slowing the wear on the banks. The diverted current swept the gravel to either side of the island and into the bay to the south, causing it to fill with gravel. waterfall on the River Orchy ;Falls and rapids The falls of the Orchy are about from Dalmally, and are about in height, forming almost a sheer drop. On the right bank, a salmon stair or ladder has formed in the rock, going round the falls, enabling salmon to ascend. There are three significant falls: Eas Urchaidh, Easan Dubha, and Eas a' Chathaidh, as well as rapids such as "Chicken Chute", "Sheep Trolley Gorge", "Sore Tooth", "Roller Coaster", "Witches Step", and "The End of Civilisation". ;Islands There are islands within the river including a large wooded one about above Inverlochy Castle; another one, Eilean a Phortaire, just below Dalmally Bridge, which is also wooded; and immediately below the latter lies a shingle island. The shingle island was separated from the fields by the drop of the bank. Glenorchy Parish Church and the burial place of the Macgregors are located on an islet formed by the river; the well of Saint Conan is nearby.
Fauna
Wildlife includes salmon and trout, as well as otter, golden eagle, short-eared owl.
Tourism
The river's falls and rapids, Grades 3–5, are enjoyed by kayakers and rafting enthusiasts. Whitewater rafting season is October to March. Fishermen can fish for trout, while salmon fishing season runs from February to October. The Dalmally Beats 1, 2 and 3 offer of double-bank fishing from the Bridge Pool in Dalmally to Sam's Box Pool in Glen Orchy. There is vehicle access to most of the pools on both banks. The Upper Craig Beat, an area of approximately between Little Colonels pool and the Boat pool allows fishing from both banks. Hill walkers climb up to Beinn Dorain, an ascent of, away.
Gold prospect
Gold mining used to take place at the Cononish mine, near Tyndrum, Scotgold obtained planning permission for development of the mine for gold and silver extraction in early 2012. In 2010, gold mining exploration began in a River Orchy glen, approximately outside the Lomond National Park. The river is reported to cross several quartz sulphide veins with significant gold mineralisation. Environmental concerns about possible gold mining were raised due to the area's proximity to both the national park and Beinn Udlaidh, a popular climbing marilyn.
