Clywedog Reservoir Levels Spark Drought Fears as Environment Agency Monitors "Exceptional Conditions"
Llanidloes, Mid Wales – Concerns are mounting over the rapidly diminishing water levels at Clywedog Reservoir, a vital regulator for the River Severn, as the Environment Agency confirms it is "closely monitoring" the situation amidst what it describes as the driest conditions in nearly 200 years. The reservoir, currently at approximately 50 per cent of its normal capacity, has seen a dramatic reduction in water volume, raising fears of widespread drought impacts.
Aerial images of Clywedog Reservoir near Llanidloes, captured last week by local resident Russell Owen, have intensified public anxiety. Owen, who has observed the reservoir for years, expressed his deep concern, stating, “It has been this low before but never this quickly.” His sentiment resonates with the stark reality depicted in the photographs, which reveal vast expanses of exposed reservoir bed previously submerged.
The Environment Agency acknowledges the severity of the situation, attributing the rapid decline to unprecedented dry weather conditions. A spokesperson highlighted the historical significance of the current drought, noting, "We’re seeing Llyn Clywedog follow similar reductions as in 2022, but 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."
Clywedog Reservoir plays a crucial role in maintaining the flow of the River Severn, one of the UK’s longest rivers, supporting ecosystems, agriculture, and water supplies downstream. The significant drop in its capacity therefore has far-reaching implications.
Both the Environment Agency and Natural Resources Wales are collaborating intensely to manage the escalating crisis. "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," the Environment Agency spokesperson added.
Earlier this month, the Environment Agency’s national report singled out Clywedog Reservoir, noting it had experienced “the greatest change in storage, with a decrease of more than six per cent, as it continues to support river flows in the River Severn.” The report further categorized the reservoir, along with almost all others across the country, as being “exceptionally low for the time of year.”
Official data from Monday, August 10, reveals the stark contrast in water levels. The reservoir stood at 55.6 per cent of its capacity, holding 27,764 megalitres. This figure pales in comparison to the 76.4 per cent capacity recorded on August 11 last year, when it held 38,151 megalitres. This substantial decrease underscores the rapid rate at which water reserves are being depleted.
The prolonged period of minimal rainfall and soaring temperatures have created a challenging environment for water management authorities. With no significant rainfall predicted in the immediate future, the continued monitoring of Clywedog Reservoir and other key water sources will be paramount to mitigating the potential impacts of a widespread drought across the River Severn catchment and beyond. The public is urged to conserve water where possible as the nation grapples with these unprecedented dry weather conditions.
