In England and Wales, overall reservoir storage is now normal or above normal for the time of year in the majority of the Environment Agency’s regions. In the south west and Midlands regions, levels are slightly below normal. Many reservoirs are now full.
The overall percentage full figures as of 10 January 2007 are given in the following table:
Region Reservoir levels Percentage full figures North East All key reservoirs or reservoir groups are at a normal level for the time of year 95 North West Two key reservoirs or reservoir groups are now full. One reservoir is slightly below normal for the time of year 98 Midlands One key reservoir is slightly below normal for the time of year 92 Anglian All key reservoirs are normal or above for the time of year 92 Thames All key reservoirs or reservoir groups are normal or above for the time of year 94 Southern All key reservoirs are at a normal level for the time of year 92 South West Two key reservoirs are below normal, one notably low 77 EA Wales All key reservoirs or reservoir groups are normal or above for the time of year 99
Overall storage for England and Wales is 94 per cent.
Reservoirs, however, provide only around 30 per cent. of water supply in the south east: around 70 per cent. is from groundwater. Groundwater levels are showing a more variable response to recent rainfall and are generally below those expected for the time of year; continued rain will be needed to restore groundwater to normal levels across the south east.
