The Megget Valley was once described as one of the most “inhospitable and bleak” spots in the Borders.
And yet, for four decades, people in Edinburgh – nearly 30 miles (50km) away – have been raising a glass in its honour.
On 30 September 1983, the Megget Reservoir was officially opened, supplying millions of gallons of water to Scotland’s thirsty capital.
It was, at the time, the biggest dam in the country.
It was not the first time that Edinburgh had turned to the Borders in its search for water supplies.
