Eleven adults and four children have been rescued from crafts on the River Shannon in separate incidents over 48 hours.
No-one was injured in any of the incidents but the RNLI Lough Ree crew has warned boat users about water levels that are continuing to fall in the area.
On Monday, the lifeboat crew came to the assistance of eight people in two separate incidents when they got into difficulty near the Hexagon Shoal on the eastern shore of Lough Ree near Killinure Point.
Yesterday, Lough Ree RNLI was alerted by a member of the public to a boat in difficulty near Hodson Bay on the western shore of Lough Ree.
Sarah Bradbury of Lough Ree RNLI Lifeboat said: 'It's great to see so many people, both locals and visitors, enjoying Lough Ree and all that it has to offer.
"As we continue to enjoy the dry weather, we'd like to remind people to respect the water and to let people know that water levels may be lower than usual and to keep to the main navigation channels where the water will be deeper."
