Release of Water from Usk Reservoir for 10 days from 31 May 2018

For information and dissemination

Richard Allen (Dwr Cymru/Welsh Water) tells me that they are planning to release a large volume of water from Usk reservoir from Thursday onwards: ‘We need to drop the reservoir level to allow essential work to be carried out so we will be releasing around 180 Ml/d for around 10 days.‘ I understand that this will be abstracted at Prioress Mill, Usk town but it will boost flows through most of the river, substantially so in the upper and middle reaches.
He also said that due to the ongoing works for the new pumping station at Prioress Mill, Welsh Water will not be abstracting its full licensed capacity at Usk.
