Yorkshire’s reservoirs have seen their largest weekly increase in more than 30 years following heavy rainfall across the region.
Stocks rose by 14.8% in the last seven days to reach 45.6%. Despite the welcome rise, levels remain well below the long-term average of 69.6% for this time of year.
The biggest inflows were recorded at:
-
Scar House Reservoir, Nidderdale – over 3 billion litres
-
Grimwith Reservoir, Yorkshire Dales – over 2.7 billion litres
-
Langsett Reservoir, South Yorkshire – over 900 million litres
-
Digley Reservoir, West Yorkshire – over 750 million litres
Groundwater and river levels have also seen a significant boost.
Dave Kaye, director of water services at Yorkshire Water, said: “The rainfall we’ve seen over the last seven days has had a significant impact – the largest weekly increase in stocks we’ve seen in 30 years.
“The rain has also recharged groundwater and the region’s rivers. The recharge of the rivers means we can enact our drought orders and permits to allow the reservoirs maximum recovery.
“While the increase is positive and very welcome after the driest summer on record, our stocks are still well below where they should be at this time of year. We hope the reservoirs and groundwater will continue to recover through the autumn and winter months so we’re in a good position entering 2026.”
He added that hosepipe restrictions will remain in place until sufficient recovery is achieved, though the situation will continue to be reviewed.
“Despite the relief of the rainfall, we are continuing our efforts to tackle more than 800 leaks per week and lay over 1,000km of new water pipes over the next five years. Once again we’d like to thank customers’ efforts to adhere to the restrictions and for those taking further steps to conserve water resources.”
