Hydrology Summary Bulletin – May 2024
The EPA has published the Hydrology Summary Bulletin for May 2024 outlining the flows in rivers, rainfall, lake levels and turlough levels, groundwater levels and spring outflows of over 300 stations across Ireland.
In May 2024, Rainfall was below average in most places, wettest in the South and north Midlands. Rainfall patterns were variable; some areas received a lot of rain in short intense bursts, especially the South and parts of the Midlands, while other areas stayed mostly dry with sunny spells at times. The month finished showery as low pressure pulled away and high pressure built from the west.
The monthly average river flows for May decreased when compared to April. 57% of river flows were in the long-term normal range for this month, while 47% of the lake and turlough monitoring stations observed levels above the long-term normal range.
Average monthly groundwater levels decreased compared to the previous month; however, 69% of the wells recorded levels above the long-term average for May.
Out of the six spring flows monitored, two were in the ‘above normal’ range and one was classified as being ‘particularly high’.
