Loch Katrine

Loch Katrine (; Scottish Gaelic: Loch Ceiteirein [l̪ˠɔx ˈkʲʰeʰtʲɪɾʲɛɲ] or Loch Ceathairne) is a freshwater loch in the Trossachs area of the Scottish Highlands, east of Loch Lomond within the Stirling council area. It mostly lies within the historic and registration county of Perthshire, with Glengyle Water and the northern part of the loch's mid-line forming part of the boundary with historic Stirlingshire. The loch is about 8 miles (13 km) long and 1 mile (1.6 km) wide at its widest point, and runs the length of Strath Gartney (Gaelic: Srath Ghartain). It is within the drainage basins of the River Teith and River Forth. It is a popular scenic attraction for tourists and day-visitors from Glasgow and nearby towns; fly and boat fishing for trout are permitted on the loch from spring to autumn. It also serves as a reservoir for the water supply of the Glasgow conurbation, some 30 miles (48 km) south, being connected by two aqueducts constructed in 1859. It is the fictional setting of Sir Walter Scott's poem The Lady of the Lake and of the subsequent opera by Gioachino Rossini, La donna del lago.
