and to the Mottram Tunnel. A statutory report, prepared under the Reservoir Safety Act 1975 and dated 12 June, stated that all five reservoirs could be overtopped during a Probable Maximum Flood. Woodhead as the fountainhead would have the most extensive improvements, and with these completed there was no danger at Rhodeswood of overtopping; however, there was weakness in the north spillway. To reduce the pressure, the roadway was consolidated to protect the north spillway from erosion, the embankment was raised by above the road, the wave wall was heightened by and the south spillway tunnel was remodelled. The work took place between 1994 and 1995.
