Hydrology Summary Bulletin for February 2023
The Hydrology Summary Bulletin for February 2023 has information on the flows in rivers, rainfall, lake levels, groundwater levels and spring outflows of over 300 stations across Ireland. Ireland is not experiencing the same inter annual drought seen across Europe since 2018, but this year we’re seeing unusually low rainfall, flows & water levels which may lead to more active water management decisions being made later this year.
Rainfall was below average everywhere, driest in the south and east of the country.
Average river flows were below the long-term average at almost all (96%) of river monitoring stations across most of the country in February 2023. Only the most northern and western parts of the country observed average river flows in the ‘normal’ range for this time of year.
Lake levels also fell during February with 58% of monitored lakes below the long-term average for this month. Average monthly groundwater levels also fell during February.
Almost three-quarters (71%) of monitoring wells were below the long-term monthly average. Similarly, almost all monitored spring outflows were below normal for this time of year.
