The data used to determine status for lakes is based on the latest data collected up to the end of the previous calendar year, in this case 2019.
Statistics on the state of the water environment are published annually in the Northern Ireland Environmental Statistics Report. WFD data is not updated each year due to the timescales of the monitoring. An interim WFD status was provided for all surface water bodies in 2018. This report can be found here.
