The weir (1) is of reinforced concrete construction. The weir (1) has a base platform (2) for mounting on a river bed or the like. Centrally located on the base platform (2) is an upstanding weir wall (3) having a substantially vertical downstream wall face (4) and an inclined upstream wall face (5). A pair of upright end walls (6, 7) sit on the base platform (2). Each end wall (6, 7) has a central slot (8, 9) in its lower face for reception of and engagement with outer side portions (17, 18) of the base platform (2) which extend outwardly of each end of the weir wall (3).
