December 2019 update

November was another fairly wet month for the region, with 111 mm of rainfall. This is 104% of the monthly average and now means that overall, the rain received in the last six months (June to November) has been 123% of the long-term average, at 574 mm. This is a stark contrast to the same period last year when the region received just 70% of average rainfall.  

Surface reservoir storage continued to increase throughout November in response to the rainfall, and by the end of the month storage was 99% of total capacity (please see the table below for our latest resource position). This compares to 55% at the same time last year.

River flows are monitored on a daily basis to ensure stream supports are switched on as the appropriate flow triggers are reached. River flows remained high throughout November, and at the end of the month most were above average for the time of year.

Stream supports, which help improve river flows, remain in operation in the following locations (as at 12/12/19):

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

Groundwater levels increased rapidly throughout October and continued to increase in November. By the end of the month most groundwater levels were well above average for the time of year.
