16. To ask the Minister for Communications, Climate Action and Environment further to Parliamentary Question No. 237 of 10 November 2020, if, in view of the fact that the turlough is now 1.75 m higher than on 6 January 2020, he will request Geological Survey Ireland using the data collected to date to produce an updated flood risk map for Funshinagh, County Roscommon; and if he will make a statement on the matter.

Geological Survey Ireland’s flood mapping at Lough Funshinagh is based on a mathematical model which relates rainfall to water level. The model is calibrated using water level data from 2016 to 2019. Then, using this model, the flood map is created with rainfall data from the last 70 years which determines the probability of various flood levels occurring in the future. Current data indicates that the relationship between rainfall and water level at Lough Funshinagh has not altered. While the rainfall in 2020 was above average, remodelling with the inclusion of data from 2020 is only one additional year to the 70 already incorporated. Any alteration to the flood map would be negligible and the current flood map is therefore considered appropriate.
