Malta’s Chadwick Lakes (Wied il-Qlejgħa) has introduced a newly rehabilitated 2km walking trail, blending nature, history, and modern conservation.
Minister for the Environment, Miriam Dalli, inaugurated the project, which features reinforced dams, restored retaining walls, and educational panels highlighting the valley’s historical and ecological significance.
Minister Dalli emphasised the project’s importance in preserving natural spaces while supporting climate resilience and agriculture. The site now stores approximately 70 million litres of water, extending retention in dams and benefiting local farmers.
Stretching from Mtarfa to Fiddien, the trail offers visitors a glimpse into a landscape where ancient water management meets modern restoration. A dedicated play area has also been added, ensuring the site is accessible to all ages.
Historically, Chadwick Lakes played a crucial role in Valletta’s Wignacourt aqueduct and Sir Osbert Chadwick’s water supply projects. Now, following extensive restoration by the Energy & Water Agency, ERA, Nature Trust Malta, and the Rabat Local Council, the valley has been transformed into an ecological hub.
Energy & Water Agency CEO Manuel Sapiano highlighted efforts to remove invasive species, including crayfish and balloon vine, to protect local biodiversity.
Native species like the White Poplar are being reintroduced, while clearing silt from the dams has improved rainwater harvesting.
Today, Chadwick Lakes is home to Malta’s only native amphibian, the painted frog, as well as indigenous trees and bird species like the European Robin and Cetti’s Warbler.
The project, completed in collaboration with Infrastructure Malta and the Environment and Resources Authority, ensures long-term accessibility, inviting locals and tourists to experience the valley’s rich natural and historical heritage.
