Current status of water resources, monitoring ground water, streams, rainfall and river flows

December 2021 update

November was a dry month with just 18 mm of rainfall across the Wessex region. This is just 17% of the monthly average. The rain received in the last six months (June to November) has been 90% of the long-term average.

Despite the dry weather our surface reservoirs remain healthy, and storage was 88% of total capacity at the end of November. This is slightly lower than storage this time last year but similar to the long-term average.

Groundwater levels at most monitoring sites declined throughout November, however at the end of the month they were average for the time of year

River flows are monitored on a daily basis to ensure stream supports are switched on as the appropriate flow triggers are reached. Stream supports are helping to improve river flows in the following locations (as at 10/12/21):

  • Chitterne (5.0 Ml/d into Chitterne Brook, nr Warminster)
  • Porton (1.5 Ml/d into Salisbury Bourne, nr Salisbury)
  • Watergates (6.5 Ml/d into Tadnoll Brook, Dorset)
