A hosepipe ban, which has been in place in Mullingar in Co Westmeath, for over five months will be lifted on Monday.
In a statement Uisce Éireann urged vigilance and said that while Lough Owel has seen some "mild recharge" with the heavy rainfall since autumn arrived, it will take time for the lake to fully recover.
"The recharge of this spring-fed lake will be dependent on consistent rainfall over autumn and winter," said Uisce Éireann Regional Technical Operations Manager Fionnuala Callery.
She is urging people to remain vigilant and continue using water wisely all year round.
"We're extremely grateful to the people of Westmeath for their efforts to conserve water since the order was introduced in early May," she said,.
"We’re doing everything we can via network initiatives to protect and maintain the water supply, but we also need the public’s continued support to protect the supply and the lake.
"Even small changes in how we use water can make a big difference," she said.
