Chadwick are a number of dams, pouring into each other, on the island of Malta. The area is locally known as Wied il-Qlejgħa (Qliegħa Valley). Their location extends from Qliegħa Valley in the limits of Mtarfa and Rabat, to Għasel Valley (Wied il-Għasel) in the peripheries of Mosta.[1] It consists of a complex system of well-planned small dams, draining into Speranza Valley, and then into the sea at Salina Bay.[2]
