The Antrim gauge recorded a peak flow of 208.7m3/s. WDR & RT Taggart and JBA Consulting were commissioned by the Rivers Agency to complete a modeling study of the Sixmilewater between Ballynure and Lough Neagh in County Antrim. The aim of which was to construct, calibrate and sensitivity test a 1-dimensional hydrodynamic InfoWorks-RS model of the Sixmilewater to enable accurate estimates of the 10 year, 100 year, 1000 year and 100 year plus Climate Change (2030) flood levels. In additional to a historic review of flood events the following reports were also undertaken:
