May 2020 update

April was a relatively dry month for the Wessex region, with 73% (49 mm) of the monthly average rainfall. The majority of this rainfall occurred during the last half of the month.  The rain received in the last six months (November to April) has been 120% of the long-term average, at 602 mm.

Surface reservoir storage declined slightly in April, and at the end of the month storage was 93% of total capacity.

River flows are monitored on a daily basis to ensure stream supports are switched on as the appropriate flow triggers are reached. River flows across the region decreased throughout most of April. The majority of flows in the north of the region ended the month slightly below average, whilst most flows in the south were normal for the time of year.

Stream supports, which help improve river flows, are in operation in the following locations (as at 22/05/2020):

  • Hullavington (1.5 Ml/d into Gauze Brook, nr Malmesbury)
  • Lower Stanton St Quinton (1.5 Ml/d into Rodbourne Stream, nr Chippenham)
  • Luckington (2.5 Ml/d into Sherston Avon, nr Malmesbury)
  • Porton (1.5 Ml/d into Salisbury Bourne, nr Salisbury)
  • South Wraxall (2 Ml/d into Chalfield Brook, nr Bradford on Avon)
  • Tetbury (2.5 Ml/d into Tetbury Avon, nr Malmesbury)
  • Watergates (6.5 Ml/d into Tadnoll Brook, Dorset) 

Groundwater levels continued to recess throughout April, and at the end of the month most were generally average for the time of year.
