38 BATH Y METRICAL SURVEY OF 



draining by the Ullapool river into Loch Broom at Ullapool. The Broom 

 basin is bordered on the south and east by the Conon and Shin basins 

 belonging to the eastern drainage system, Loch Achall lying about 5 miles 

 west of Loch an Daimh in the Shin basin, and Lochs Droma and a' Bhraoin 

 about the same distance north of Loch Fannich in the Conon basin. 



Besides the Broom and Ullapool rivers, the basin includes the river 

 Kanaird, flowing into the wide part of Loch Broom, north of Ullapool, and 

 the Strathbeg river, flowing into the head of Little Loch Broom, lying to 

 the south-west of Loch Broom. The scenery of the district is very fine, 

 and the lochs afford good fishing, though preserved. They all contain 

 trout, and salmon also are got in Loch Achall. Some years ago Loch 

 Droma was greatly enlarged, and the fishing vastly improved. 



Loch a' Bhraoin (see Plate XIV.). Loch a' Bhraoin lies about 7 miles 

 to the south of the head of Loch Broom, surrounded by high hills ; on 

 the south a' Chailleach rises to 3276 feet above the sea, though the slope 

 is gentle. The loch trends in a north-east and south-west direction, and 

 is over 2J miles in length. The maximum breadth is nearly half a mile, 

 and the mean breadth a quarter of a mile. Its waters cover an area of 

 about 419 acres, or two-thirds of a square mile, and the area draining 

 into it is about 13 square miles. The maximum depth of 73 feet was 

 recorded about half a mile from the north-east end, and nearer the 

 southern than the northern shore. The volume of water is estimated at 

 669 million cubic feet, and the mean depth at nearly 37 feet, or half the 

 maximum depth. The loch was surveyed on August 19, 1902, when the 

 elevation was found to be 812-5 feet above the sea about a foot lower 

 than that determined by the Ordnance Survey officers on August 29, 1868, 

 viz. 813*4 feet. The keeper stated that the water might fall a few inches 

 lower, and rise about 5 feet higher, than the level on the date of the 

 survey. The conformation of the basin is simple, the contours following 

 approximately the outline of the loch, though the soundings indicate a 

 few minor undulations. 



Temperature Observations. The temperature of the surface water was 

 58-0 Fahr. at 11 a.m. on the date of the survey, and 55-7 in the after- 

 noon; while the following serial, taken in the deepest part of the loch 

 at 4 p.m., showed a range of only 2'5, or a total range throughout the 

 waters of the loch of 4-3.

Loch Droma (see Plate XV.). Loch Droma (or Druim) lies in the 

 forest of Braemore, about 8 miles from the head of Loch Broom, and 

 nearly 6 miles east of Loch a' Bhraoin ; to the north lies Meall Leacachain 

 (2028 feet), and to the south Beinn Liath Bheag (2173 feet). The loch
