英格兰和威尔士地区正面临严重干旱,五座关键水库的水位处于"异常低"状态[1]。截至8月11日,Wimblewall水库蓄水量仅46%,Clatworthy为48%,Hanningfield和Clywedog均为56%,Dove集群则为69%[1]。环境署数据显示,英格兰水库总水位已下降至66%,环比下降3个百分点,且比历年同期低14个百分点[1]。在32座战略性重要水库中,仅有4座处于正常水位[1]。
极端高温和降雨稀少是此次干旱的主要原因[1]。国家水文监测项目称7月份的干旱情况"前所未有",并预计水流异常将持续到秋季[1]。专家警示,未来的降雨模式至关重要。Liz Bentley教授表示:"关键是干天气会持续多久,如果秋冬降雨量低,将陷入真正困境"[1]。Alastair Chisholm指出:"过去5年记录3次干旱,国家进入新领域"[1]。
供水压力日益加剧。环境署预估,在无紧急行动情况下,英格兰公共供水到2055年可能面临每天50亿升的短缺[1]。当前,英格兰和威尔士每天浪费28.7亿升饮用水[1]。为缓解长期供应问题,英国政府已下令修建两座大型水库,分别位于东英吉利和林肯郡,但这两个项目分别需要到2036年和2040年才能竣工[1]。自1992年以来,英国未建设过新的水库[1]。
Five critical reservoirs across England and Wales have fallen to "exceptionally low" water levels as the region continues to grapple with extreme heat and minimal rainfall [1]. As of August 11, Wimblewall reservoir stood at just 46 percent capacity, while Clatworthy registered 48 percent, Hanningfield 56 percent, Clywedog 56 percent, and the Dove cluster remained at 69 percent [1]. Across England overall, reservoir levels have declined to 66 percent of total capacity, down three percentage points from the previous week and 14 percentage points below the historical average for this time of year [1]. Of 32 strategically important reservoirs, only four currently maintain normal water levels [1].
The drought situation reflects an unprecedented dry spell in July, according to the National Hydrological Monitoring Programme, with abnormally low water flows expected to persist into autumn [1]. Water officials warn that if rainfall remains inadequate through the fall and winter months, the country faces a genuine supply crisis [1]. The Environment Agency has projected that without emergency intervention, England's public water supply could face a daily shortfall of 5 billion liters by 2055 [1]. Contributing to the pressure, England and Wales loses 2.87 billion liters of drinking water daily through leaks [1], while no new reservoirs have been constructed since 1992 [1]. The government has ordered construction of two large-scale reservoirs—one in East Anglia and another in Lincolnshire—though neither is expected to be operational until 2036 and 2040 respectively [1].
