The
River Tay
The
River Tay is the longest river in Scotland. From its source in
Ben Lui (3708 ft.), a mountain on the borders of Perthshire and
Argyllshire, it pursues a mainly north-easterly direction to Logierait,
where it curves to the south by east as far as Dunkeld; there
its course turns to the south-east to the mouth of the Isla, where
it bends towards the south by west to the vicinity of Scone. From
this point it makes a sharp descent to the south by east beyond
the county town, when it sweeps southeast to near Newburgh in.
Fifeshire, where it again faces the north-east as far as Broughty
Ferry, whence it flows straight eastwards into the North Sea,
off Buddon Ness in Forfarshire, after a total run of 117 miles.
During
the first 11 miles it is known as the Fillan and discharges into
Loch Dochart. From the lake it emerges as the Dochart, which enters
Loch Tay at Killin. Flowing through the loch, it issues at Kenmore
under its proper name of Tay. From hence to the sea its course
measures 78 1/2 miles., from which we may deduct 25 miles as the
length of the Firth of Tay, leaving 53 1/2 m. as the length of
the stream between Kenmore and the mouth of the Earn. Its principal
affluents on the right are the Bran, Almond and Earn, and on the
left the Lyon, Tummel and Isla. Along with its tributaries, therefore,
it drains all Perthshire and portions of Forfarshire and Argyllshire,
having a catchment basin of 2400 sq. m. In many parts the current
is impetuous, and in flood has occasionally wrought much havoc,
certain of the inundations being historically important. Its mean
discharge of water every minute is estimated to amount to 273,000
cubic ft., a larger outpour than that of any other river in the
United Kingdom.
Vessels
make Dundee at all stages of the tide, and the estuary is navigable
to Newburgh by vessels of 500 tons, and as far as Perth by ships
of 200 tons. The navigation, however, is seriously obstructed
by shifting sandbanks. The estuary varies in width from 1/2 mile
to fully 3 miles. its mouth. The principal points on the river
are Crianlarich on the Fillan (with stations on the West Highland
and Callander to Oban railways), Luib and Killin on the Dochart,
Kenmore, Aberfeldy, Dunkeld, Birnam, Stanley, Scone, Perth and,
on the north shore of the firth, Errol, Dundee, Broughty Ferry
and Monifieth, and, on the south shore, Newburgh, Newport and
Tayport. It is bridged at Kenmore, Aberfeldy, Logierait, Dunkeld,
Caputh and Perth (3).
The
first railway viaduct across the firth at Dundee was nearly two
miles long and had been in use for some eighteen months from the
date of its opening in 1877. During the night of the 28th of December
1879, however, while a great gale was at the height of its fury,
the passing of a train over the central section gave purchase
to the tempest and that portion of the structure was blown down
along with the train and the unfortunate travellers. Some 75 to
90 persons are supposed to have perished. The second bridges of
somewhat lower height, 2 miles and 73 yds. in length, was erected
60 ft. higher up stream and opened in 1887. The Tay is famous
for salmon, the annual catch in the river and estuary being the
most valuable in Scotland. There are hatcheries
for the artificial breeding of salmon, the fish being liberated
from the ponds about the age of three years. In respect of riparian
scenery the Tay as a whole is the most beautiful river in Scotland,
the stretch between Logierait and Cargill, particularly the reaches
above and below Dunkeld, being universally admired.
