78 THE SALMON RIVERS OF SCOTLAND 



and indeed there is a considerable resemblance between the falls, 

 since there is here an S -shaped rapid of great force, followed by a 

 precipitous drop of the water. Dunalastair Fall is, in fact, a replica 

 of the negotiable part by the Falls of Tuminel, but without the 

 higher and more abrupt section of the fall on the right side. The 

 difference of level in the total obstruction is not less than 18 or 19 

 feet, but the abrupt part of the fall into the pool below is not so 

 high as in the case of the Tummel Fall. From the centre of the 

 rapid to the pool below is about 13 J feet. A great part of the rock 

 barrier could be removed by blasting, or alternatively a pool-pass 

 could be constructed round a great part of the fall on the left 

 bank. 



Even in its present state, however, fish manage to negotiate it. 

 They have been watched making the ascent, and they have been 

 caught in the pools above. Some extremely nice water exists in 

 those upper waters, and I have known of 4 fish being hooked 

 within an hour in the large pool below Dunalastair House. Some 

 excellent spawning ground also exists between Dunalastair and the 

 foot of Loch Rannoch. 



RIVER GARRY. 



This river flows out of the loch of the same name, situated within 

 a short distance of Dalnaspidal Railway Station, and flows through 

 Struan, Blair Atholl, and Killiecrankie, to join the Tummel at 

 Faskally, a distance of 22 miles. Loch Garry is fully 2 J miles long, 

 and has an average breadth of less than quarter of a mile. It is, 

 for its size, a rather deep loch basin with two depressions, one 113 

 feet, which is the maximum depth of the loch situated towards 

 the northern end, and the other and larger depression yielding a 

 sounding of 105 feet. The loch is about 1320 feet above sea- 

 level and drains an area of fully 22 square miles of steep hill 

 country. 



The river from the time it emerges through alluvial deposits close 

 to the outlet from the loch deposits which cause a shallow area for 

 about half a mile in the loch itself rattles along over a long suc- 

 cession of schist ledges which dip south-east in the direction of the 

 river. Before Struan is reached (12 miles) one or two abrupt little 

 cascades have been passed, and in all this rocky bed no great amount 

 of gravel is allowed to settle, hence a great part of the upper Garry 

 is of little use as spawning ground. At Struan a double fall occurs 

 in the gorge immediately below the railway station. This double
