The Loch of Harray is the largest loch of Mainland Orkney〔 and is named for the nearby parish of Harray. It lies immediately to the north of the Loch of Stenness and is close to the World Heritage neolithic sites of the Stones of Stenness and Ring of Brodgar. In Old Norse its name was ''Heraðvatn''.〔Pedersen, Roy (January 1992) ''Orkneyjar ok Katanes'' (map, Inverness, Nevis Print)〕 ==Hydrology== The loch was surveyed〔 on 21 August 1903 by Sir John Murray and later charted as part of the ''Bathymetrical Survey of Fresh-Water Lochs of Scotland 1897-1909''. Murray observed that Loch of Harray is a freshwater loch, the largest in all Orkney with an area of approximately and volume of and that it is somewhat influenced by the tides in the Hoy Sound although there is little variation in its level. The loch is connected to the Loch of Stenness at the Bridge of Brodgar.〔"Lochs of Harray and Stenness Site of Special Scientific Interest" Midas 1083. SNH〕 The two lochs together cover an area of making the two combined the ninth largest loch in Scotland by area (as listed by Murray and Pullar (1910)). Murray recorded that despite there being an inlet allowing the free flow of water from the Loch of Stenness it has little impact on the marine biology of Harray and no seaweed was present, the water tasted fresh and normal freshwater plankton were seen. 〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Loch of Harray」の詳細全文を読む スポンサード リンク
