A huge Welsh reservoir is looking partially empty, leaving some passersby concerned about early signs of drought. But the water levels at Llyn Peris in Snowdonia have been lowered to enable refurbishment work to take place.
The sides of the reservoir, which is near Llanberis in Gwynedd, will remain exposed for part of the summer so its dam, pipes and tunnels can be checked. Drilling rigs and plant machinery will be on-site, reports North Wales Live.
The water levels have dropped by 14 metres and are expected to stay low for around 80 days while the checks are carried out. The water has been pumped 1,757ft up Elidir Fawr and is being stored in an upper reservoir, Marchlyn Mawr.
