An elderly cyclist drowned today when he fell into a stream in Co Galway.
Gardaí believe the man was on his bike at Screeb near Rosmuckl in Connemara when he slipped into the shallow water. His body was spotted at 12.15pm.
Gardaí at Salthill are investigating the incident but are not treating his death as suspicious.
A post mortem exam will be carried out to determine an exact cause of death.
Irish Water Safety issued a warning over rising water levels due to heavy rain.
"Even though a poor weather forecast is likely to raise water levels flowing in to our rivers, harbours and bays, thousands of people will still enjoy water-based activities over the August bank holiday weekend," the organisation said.
It made safety recommendations for all those involved in activities such as surfing, angling, sailing, swimming, canoeing and diving in conditions that may be preceded by inclement weather, including the use of appropriate personal flotation devices.
The organisation said holiday scenes at Irish and foreign destinations "can often mask hidden dangers".
"Beaches and swimming pools may not be guarded and warning signs may differ. Swimming in the early morning and late at night, without lifeguard supervision dramatically reduces your chances of being saved."
