Looking at the dry spell from a hydrological point of view is more complicated because the conventional water year starting in October does not correspond very closely to the natural replenishment period for reservoirs and groundwater resources in the English lowlands. After consultation with the Centre for Ecology and Hydrology (Wallingford), it was decided that the period starting November would provide the best characterisation of the severity and extent of the dry spell.

For comparison purposes, rainfall information for the following additional periods starting October 2004 or October 2005 (October start of conventional water year) have been produced.
