March 2020 update

February was an exceptionally wet month for the region, which saw 228% (151 mm) of the monthly average rainfall. This was the wettest month since February 2014, when 156 mm rainfall fell across the region. The rain received in the last six months (September to February) has been 137% of the long-term average, at 756 mm.

Surface reservoir storage remained at 100% of total capacity throughout February (please see the table below for our latest resource position).

River flows are monitored on a daily basis to ensure stream supports are switched on as the appropriate flow triggers are reached. The continued rainfall in February meant that all river flows remained well above average throughout the month.

Stream supports, which help improve river flows, are in operation in the following locations (as at 06/03/2020):

  • Watergates (6.5 Ml/d into Tadnoll Brook, Dorset)

Groundwater levels remained high throughout February, and at the end of the month all were well above average for the time of year.
