September 2020 update
Whilst the beginning of August was largely dry, the latter part of the month saw widespread heavy rainfall. This means that overall, the region received 177% (108 mm) of the monthly average rainfall. The rain received in the last six months (March to August) has been 98% of the long-term average.
Surface reservoir storage declined as expected at the start of August, however reservoirs did respond to the rainfall at the end of the month. Reservoir storage for the week commencing 31st August was 63% of total capacity. Pumped storage (where we pump water from rivers to top up storage in the surface reservoirs) was used to support Luxhay reservoir at the beginning of the month.
