Wales is on high alert as it faces its worst environmental drought crisis in years, with river levels plummeting to near record lows. A crucial announcement from Natural Resources Wales (NRW) is expected today, July 22nd, confirming the severity of the situation. The country has seen a meagre 5% of average July rainfall so far this month, exacerbated by a drought-stricken spring.
The dire situation is taking its toll on Wales' natural environment. Afonydd Cymru, representing the nation's river trusts, has highlighted 'significant problems' caused by low river flows, including fish and aquatic wildlife deaths. The scorching heat – with some rivers reaching a searing 28°C – is putting further strain on ecosystems. Farming unions are equally concerned, warning of failing crops and heat-stressed livestock.
Last week, NRW upgraded the drought status for north and south-east Wales to 'prolonged dry weather', prompting increased monitoring of waterways and crucial wildlife sites. Huwel Manley, NRW's Head of Operations in south-west Wales, pointed out that several watercourses have dried up completely, while larger rivers are experiencing unprecedentedly low flows. Rivers in north Wales include the Clwyd, Alwen, Alyn, Clywedog, Dyfi, and Conwy, as well as the Wye, which spans mid-Wales and the English border.
Efforts to alleviate the situation involve releasing additional water from reservoirs into rivers like the Clwyd, Wye, Severn in south-east Wales, and Dee in north-east Wales. Although some rain is forecast for the weekend ahead, experts caution that it will take considerable time for river systems to recover fully. The 'environmental drought' classification signifies immediate and detrimental effects on ecosystems due to water scarcity and dry soils – distinct from a direct threat to drinking water or household supplies.
Gail Davies-Walsh, Chief Executive of Afonydd Cymru, warned that Wales' waterways were already under strain from pollution, with the current drought exacerbating this issue. She urged the public to reduce their water usage, despite understandable frustrations with water companies over issues like sewage spills. Practical advice includes opting for showers over baths and providing water in gardens for local wildlife, helping protect vulnerable ecosystems.
