Lake and lough swimming spots in Ireland

Inland freshwater swimming in Ireland — lakes and loughs with published bathing-water monitoring.

Freshwater bathing waters monitored under the same EU Bathing Water Directive as coastal beaches, though the reference values differ: inland waters are assessed against a higher E. coli threshold than coastal ones, because freshwater bacteria behave differently.

Water body type is identified from the spot's name, because neither agency publishes it. A lake whose name does not say so will be missing from this list.

17 spots, grouped by county. Each shows its current swim status — an award or a classification is not the same as today’s water.

Common questions

How many lake and lough swimming spots are there in Ireland?
17 — this page lists all of them, grouped by area, with each one's current swim status.
What does this mean?
Freshwater bathing waters monitored under the same EU Bathing Water Directive as coastal beaches, though the reference values differ: inland waters are assessed against a higher E. coli threshold than coastal ones, because freshwater bacteria behave differently.
Can I swim at all of these right now?
No. 1 of these 17 spots is currently flagged, including 1 under an active do-not-swim notice. A rating or an award describes a past assessment; the status on each spot page is today's. Neither is a safety clearance — bathing-water monitoring covers bacterial quality only, and says nothing about tides, currents, swell or cold-water shock.
Which areas of Ireland have the most?
Monaghan (10), Westmeath (3), Clare (2). They are spread across 5 areas in total.
