Gladhouse Reservoir - Penicuik

Gladhouse Reservoir, formerly Moorfoot Loch, is a reservoir in Midlothian, Scotland, five miles (8 km) south of Penicuik. It is the largest area of freshwater in the Lothians. It was created in 1879 by the engineer James Leslie. The 460-acre (1.9 km²) reservoir in the Moorfoot Hills is one of a group of reservoirs which supply Edinburgh with water. It is fed by the River South Esk.

Gladhouse Reservoir is also a Site of Special Scientific Interest or SSSI, and a Special Protection Area. It is an important roosting site for Anser brachyrhynchus, the Pink-footed Goose. There are three islands in the reservoir.
