Northumberland, England, UK · 1975–1981 (Built); 1982 (First flooded)

The judgement call

Account-gated at launch

Designed to store water for the North East of England and manage water resources through the Tyne Tees Transfer scheme [Cool Geography, NWG PDF] - The scheme quadrupled the amount of stored water in the region, providing significant water supply security [ICE] - The dam\'s integrity and the safety of communities are continuously monitored [Insight Terra]

Key engineering challenges

Construction of the largest man-made reservoir in the UK, involving significant civil engineering works for the dam and associated infrastructure [ICE] - Managing the environmental impact of flooding the Kielder Valley and ensuring the safety of surrounding communities [Kielder Waterside, Insight Terra] - Implementing the Tyne Tees Transfer scheme to enable water movement around the region, providing water supply resilience [NWG PDF]
