Old Photograph The Queen Of Earn St Fillans Scotland

Old photograph of tourists on The Queen Of Earn cruise ship on Loch Earn on by St Fillans in Highland Perthshire, Scotland. Loch Earn is a freshwater loch in the central highlands of Scotland. The name is thought to mean " Loch of Ireland ", and it has been suggested that this might derive from the time when the Gaels were expanding their kingdom of Dál Riata eastwards into Pictland. Lochearnhead is the centre for the water sports activities on the loch; water skiing, canoeing and sailing. The loch is also stocked regularly with brown and rainbow trout and fishing, by permit, is possible from the shore and by boat. Loch Earn is unusual in that it has its own apparent tidal system, or seiche, caused by the action of the prevailing wind blowing along the loch. This wind pressure on the surface causes the water level to build up at one end of the loch. As with all damped mechanical systems, applied pressure can result in an oscillation, and the water will return to the opposite end of the loch over time. In the case of Loch Earn, this has a period of 16 hours and the effect can be measured, but is difficult to observe. The resulting currents can create complex turbulence patterns, as higher layers of warmer waters mix with the lower lying colder waters of the loch. Other bodies of fresh water which experience this seiche effect include Lake Geneva, Lake Garda, the Great Lakes and Lake Baikal.
