Loch More, Caithness

Loch More is a freshwater loch in Caithness, Scotland, about south of Thurso. It is a shallow flat-bottomed basin, in common with most of the nearby lochs.
The overflow from the loch is taken by the River Thurso, which, after a windy course of, flows into the Pentland Firth at the town of Thurso. The main inflow comes from the Sleach Water and the upper part of the River Thurso. The latter is formed by a union of Rumsdale Water and Glut Water, whose source to the south-west is at a height of around, about upstream from Loch More.
The loch was originally an irregular round shape, less than a mile across, with a surface area of about. The average depth was only reaching a maximum of about. However, in 1907-1908 a dam was built at the outflow into the River Thurso, which raised the level of the loch by. Its purpose was to control the amount of water in the downstream River Thurso, thus improving the quality of salmon fishing. As a result, the area of the loch increased to, with a depth up to a maximum of, depending on the amount of water discharged. The length of the loch is now.
The area draining into Loch More is about, an area 240 times greater than the original size of the loch, an unusually large catchment area for such a small body of water.
The loch is about above sea level.
