THE FRESH- WATER LOCHS OF SCOTLAND. 261 



LOCHS OF THE CONON BASIN. 



FOURTEEN lochs draining into the Cromarty firth were surveyed by the 

 staff of the Lake Survey, viz., Lochs Crann, a'Chroisg, Gown, Achanalt, 

 a* Chuilinn, Fannich, Luichart, Beannachan, Achilty, Garve, Kinellan, 

 Ussie, Glass, and Morie. The majority of these lochs drain by the river 

 Conon into the head of the Cromarty firth, while Lochs Glass and Morie 

 drain by independent streams, which fall into the Cromarty firth on 

 its north-western shore. It has been found convenient, also, to include 

 in this place a description of Loch Eye, situated between Cromarty 

 firth and Dornoch firth. The drainage area under consideration is 

 indicated in the index map of the district (Fig. 44), by reference to 

 which the relations between the various lochs will be readily understood, 

 and extends from the mouth of the Cromarty firth on the east to the 

 heights of Carn Breac and An Groban on the west, Carn Chuinneag 

 on the north, and Sgorr a' Choir-Ghlais on the south. The total area, 

 as measured by the planimeter on the 1-inch Ordnance Survey maps, is 

 over 770 square miles, and of this total 336 square miles (or one-half) 

 drain into the lochs now to be dealt with, as will be seen from the 

 summary table. 



The headwaters of the basin take their rise on the flanks of Carn 

 Breac, flowing by various streams into Loch na Moine Moire and Loch 

 an t-Sior (which were not sounded), thence into Loch Crann and Loch 

 a' Chroisg, the outflow from which is carried by the river Bran into 

 Loch Achaualt and Loch a' Chuilinn, and thence into Loch Luichart. 

 Shortly after leaving Loch a' Chroisg the river Bran receives the outflow 

 from Loch Gown, which is fed by the Allt Gharagain, taking its rise 

 on the flanks of Moruisg (3026 feet), and shortly before entering Loch 

 Luichart the river Bran is joined by the river Fannich bearing the 

 outflow from Loch Fannich, which is fed by various streams draining 

 the flanks of a grand series of mountains exceeding 3000 feet in height. 

 After the junction of the Bran and the Fannich the river receives the 

 name of Conon, and shortly after leaving Loch Luichart it is joined by 

 the river Meig, bearing the outflow from Loch Beannachan, taking its 

 rise among lofty mountains culminating in Sgurr a' Chaoruinn (3452 

 feet). Still further on the river Conon is joined by the Black Water, 

 bearing the outflow from Lochs Garve and Achilty, and taking its rise
