WATER stocks in Yorkshire Water's reservoirs rose for the first time in 19 weeks after heavy downpours across the region.
But Yorkshire Water chiefs say reservoir levels remain low for the time of year - at 46% full.
They are continuing to advise customers to use water wisely to allow stocks to replenish for the new year.
An average of 25mm of rain fell across the region last week causing the levels at some of reservoirs to rise dramatically.
The rainfall also enabled the water company to increase water abstraction from other sources.
River flows on the Derwent, Ouse, Ure and Wharfe are now at such a level that a third of the 1.24bn litres of water the company supplies each day is taken from them.
Richard Flint, Yorkshire Water's director of water business, said: "Although it rained last week and reservoirs rose we are still working hard to ensure that we do not have any problems next year regarding river flows.
"We take our responsibilities to the environment very seriously and we are monitoring the situation on a weekly basis."
More river water could be taken now, for example, to allow reservoirs to recover fully from the long, dry summer and ensure river flows were protected next year.
