June 2019 update
Following lower than average levels of rainfall in April (79%), May was another dry month with just 56% of the monthly average rainfall falling. Whilst this was preceded by close to average levels of rainfall in February (95%) and March (118%), the rain received in the last six months (December to May) has been just 83% of the long-term average, at 378 mm.
Surface reservoir storage decreased slightly throughout the month, and by the end of May storage was 92% of total capacity (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. In general, river flows decreased throughout May in response to the dry weather. Flows in the north of the region are now below average for the time of year, whilst they remain similar to what would be expected for this time of year in the south. Stream supports, which help improve river flows, are in operation in the following locations (as at 14/06/19):
- Briantspuddle (6 Ml/d into River Piddle, Dorset)
- Chitterne (2.7 Ml/d into Chitterne Brook, nr Warminster)
- Porton (1.5 Ml/d into River Bourne, nr Salisbury)
- South Wraxall (2.0 Ml/d into Chalfield Brook, nr Bradford on Avon)
- Watergates (6.5 Ml/d into Tadnoll Brook, Dorset)
- Yarde Lane (1.5 Ml/d into Pimperne Stream, Dorset)
Groundwater levels across the region are lower than they were this time last year. In Dorset, levels are broadly average for the time of year, whilst levels in Wiltshire are now below average.
