What to expect

Completed in 1916, Derwent Dam was constructed alongside neighbouring Howden Dam to supply fresh water to the growing cities of Derby, Leicester, Nottingham, and Sheffield. Built from locally quarried gritstone, its distinctive Gothic-inspired towers and elegant design make it one of the most architecturally impressive dams in the country. 

The dam is perhaps best known for its connection to Operation Chastise. During the Second World War, pilots of the RAF’s 617 Squadron practised low-level flying over Derwent Reservoir before carrying out the famous Dambusters raid in 1943. Interpretation boards and memorials around the site tell the story of these historic training flights, making Derwent Dam an important destination for both history enthusiasts and aviation fans. 

We’ve found Derwent Dam to be much more than a historic landmark. It’s also the starting point for some of the Peak District’s finest walks, with routes leading around Derwent and Howden Reservoirs, through ancient woodland, and onto the surrounding moorland. When the reservoir is full and water cascades over the dam’s impressive spillway, it’s one of the most spectacular sights in the national park.
