50% of our supply is from surface water (reservoirs and rivers) and 50% of our supply is from groundwater stored in underground aquifers.
After a very wet June with over 200% of our average rainfall, July was slightly above average at 117% of the long term average (1961-1990).
The rain fell mainly during heavy thunderstorms at the end of the month following the hot dry weather, this rainfall was widely dispersed across the region with some areas receiving only 50% and others over 130% of their long term average.
Soil moisture deficit is average for the time of year, however we are seeing unusual summer recharge in out North Lincolnshire Limestone aquifers following the very wet June.
River flows range from above normal in the North of our region to exceptionally low levels in the East of our region, base flows continue to remain low following the lack of winter recharge at the start of year.
Groundwater levels are below normal in the East of our region and above normal in the north of the region.
We consider the current water resources situation to be secure and don’t anticipate to enforce any supply restrictions this summer, however we continue to monitor the situation very closely undertaking additional water quality and water level monitoring as well as continuing to model the impact of a dry autumn and 2nd dry winter on our resources.
We ask our customers to remain “Waterwise” whatever the weather. Get some top tips on how to save drops.
The graphs below show monthly rainfall for the region compared to average and the volumes held in our main storage reservoirs up until the end of July 2019.
The Environment Agency also monitors the water resource situation and complies a monthly report, available from their website.
