Llyn Clywedog Reservoir Levels Plummet Amidst Historic Drought, Sparking Water Conservation Appeals
Llanidloes, Powys – Llyn Clywedog, a vital reservoir near Llanidloes that plays a crucial role in regulating the River Severn flows, has experienced a significant and concerning decline in water levels in recent weeks. The dramatic drop comes as hot, dry weather conditions persist across Wales, prompting urgent calls for water conservation from authorities and utility companies.
The Environment Agency and Natural Resources Wales are working in close collaboration to assess the escalating impact of the ongoing drought. A spokesperson for the Environment Agency confirmed, "We are working with Natural Resources Wales to closely monitor dry weather conditions across the whole of the River Severn, including at Llyn Clywedog which is used to help regulate flows along the river."
Images shared with the County Times vividly illustrate the severity of the situation, showing vast expanses of exposed shoreline and noticeably receding water levels at Llyn Clywedog. The sight serves as a stark reminder of the relentless dry spell gripping the region.
The current decline at Llyn Clywedog mirrors reductions seen in 2022, but this year presents an even more dire picture. "This year we have had the driest July in 190 years and continued dry weather conditions are putting greater pressure on the whole Severn catchment," the Environment Agency spokesperson added. "Teams across the two organisations are working together to respond to the exceptional conditions we’re experiencing. We will continue to keep the situation under review as conditions develop."
Rapid Decline Raises Alarm
Earlier this month, serious concerns were raised regarding the rapid rate at which the reservoir’s water levels were falling. The Environment Agency recently reported that Llyn Clywedog had experienced the most substantial monthly reduction of any reservoir group it monitors.
"At the end of July, reservoir storage had decreased at all of the reservoirs or reservoir groups that we report on," an Environment Agency statement revealed. "The largest decrease was recorded at Clywedog where storage fell by 29 per cent when compared to the previous month."
This significant drop underscores the unprecedented nature of the current drought conditions affecting Wales.
Water Company Urges Responsible Use
In response to the deteriorating situation, Hafren Dyfrdwy, the local water company, has issued an appeal to its customers to use water judiciously. An update released on August 12th stated: "August continues to bring hot, dry conditions to our region. Together, we can conserve our water. We’re closely monitoring the situation to help preserve water and maintain reliable supplies."
The company encouraged residents to adopt simple but effective water-saving habits, such as opting for watering cans instead of hosepipes and only watering plants when absolutely necessary. Despite the visible reduction in water, Hafren Dyfrdwy maintains that storage at Llyn Clywedog remains on target at 55 per cent.
Reservoir’s Role in River Management
Llyn Clywedog’s primary function extends beyond local water supply; it is instrumental in supporting the ecological health and industrial needs of the River Severn. Earlier this summer, the Environment Agency confirmed that controlled releases had been made from the reservoir to help maintain adequate flows along the River Severn during the prolonged dry weather.
A spokesperson confirmed in June: "We made controlled releases from Llyn Clywedog Reservoir on Saturday to support flows along the River Severn. We monitor and regulate the Severn to make sure demands for water are met without compromising the river’s ability to support the natural environment."
Widespread Drought Concerns Across Wales
The concerns over Llyn Clywedog’s diminishing levels are part of a broader picture of drought affecting much of Wales. Following a record dry July and an exceptionally warm summer, the Welsh Government, Natural Resources Wales, and the Environment Agency have all warned that persistent hot weather is placing increasing pressure on rivers, reservoirs, and overall water supplies across the country.
As communities across Mid Wales anxiously await a sustained period of rainfall, agencies continue to monitor the situation closely, highlighting the delicate balance between water demand and environmental preservation in the face of a changing climate.
