June Hydrology Bulletin
The Hydrology Summary Bulletin for June 2023 outlines the flows in rivers, lake levels, groundwater levels, and spring outflows of over 300 stations across Ireland, along with rainfall.
Rainfall for June was generally below the long-term average in most places across the country. The
monthly average river flows for June fell at almost all river monitoring since May and were below
the long-term average for this month. Almost two-thirds (65%) of river stations were below the
normal range for June. Similarly, 58% of lake and turlough stations observed flows below the normal
range for this month.
Average monthly groundwater levels for May also fell at 97% of monitoring wells with more than
half (57%) of monitoring wells observing levels below the long-term average for June. Similarly,
most monitored spring outflows were in the normal range or below average for this time of year.
