Works, to the cost of IR £750,000, were undertaken on the river in the late 1940s and early 1950s to improve drainage in the river’s catchment area. As part of the Arterial Drainage Scheme, designed to tackle poor drainage caused by Ireland’s relatively low-lying topography, the river was deepened and widened, leaving the river with the high banks distinctive of many of the rivers in the Irish midlands that received this treatment. More recently, in late 2008 the river was diverted from the N52 road beside Mullingar in order to accommodate a new roundabout and bridge.
