1911 Encyclopædia Britannica/Tay, Loch
TAY, LOCH, the largest lake in Perthshire, Scotland. It is situated about the middle of the county and has a flattened ogee form, with a general trend from N.E. to S.W. It is 14½ m. long from Killin at the head to Kenmore at the foot, from ½ m. to fully 1 m. wide. The maximum depth is 508 ft., the mean depth 200 ft. The lake lies 355 ft. above the sea, covers an area of 6550 acres, or over 10 sq. m., and has a drainage basin of 232 sq. m., including the overflow from Lochs Dochart and Tubhair. It receives at Killin the rivers Lochay and Dochart and discharges by the Tay at Kenmore. Ben Lawers (3984 ft.) rises near the left bank. There are piers at Killin, Ardeonaig, Lawers, Fernan and Kenmore, at which the steamers call during the tourist season; ferries at Ardeonaig and Lawers; and a coaching road on the left shore and a somewhat longer and more hilly road on the right. At the foot of the lake is an island containing the ruins of the priory which was founded in 1121 by Alexander I. in memory of his wife Sibylla, daughter of Henry I. She was buried here. Loch Tay enjoys great repute for its salmon-fishing.
