One of Britain\u2019s oldest fly\u2011fishing clubs has sent a pre\u2011action letter accusing the Environment Agency of unlawfully abstracting water and devastating the only known brown trout breeding stretch between Ware and Stanstead Abbotts, warning it will seek a judicial review if flows are not restored.<\/p>\n<\/div>\n
\u201cAt a time when the regulation of our waterways is under such intense scrutiny you would assume that the Environment Agency would be desperate to do the right thing. Well, that time has come,\u201d Feargal Sharkey, chair of Amwell Magna Fishery, said in a statement to the Standard as he accused the Environment Agency of draining a two\u2011mile stretch of the River Lea between Ware and Stanstead Abbotts by unlawfully abstracting water. The charge, brought by one of Britain\u2019s oldest fly\u2011fishing societies, has rapidly escalated from local dispute to potential legal challenge. (The club\u2019s history underlines its long\u2011standing stewardship of the reach.) <\/p>\n
Lawyers acting for the fishery say flows on the affected section fell sharply after 3 June 2025\u2014from roughly 156 million litres a day to about 66 million\u2014and briefly plunged to some 30 million litres on 19 June, a reduction they say has devastated the only known breeding population of brown trout on that stretch. According to the fishery\u2019s legal team, represented by Leigh Day, the club has sent a pre\u2011action protocol letter demanding immediate restoration of flows and has warned it will seek a judicial review if abstraction does not cease. The Environment Agency has declined to comment publicly while legal proceedings are pending. <\/p>\n
The implication of such flow reductions reaches beyond angling loss. The fishery and its advisers say the drop has damaged protected habitats and fish spawning grounds. Local conservation organisations point out that the River Lea corridor around Amwell lies within a network of internationally and nationally designated sites, including areas recognised under Ramsar and Site of Special Scientific Interest protections, which carry statutory duties to maintain water quality and ecological flows. <\/p>\n
The Amwell Magna Fishery is not a new claimant. Its own records show a continuous interest in the reach dating back to the nineteenth century, with restoration work completed around 2018 aimed at improving brown trout habitat and ongoing monitoring of wild trout stocks. That history underpins the club\u2019s insistence that recent changes are both measurable and harmful to the delicate ecology the volunteers and anglers have worked to protect. <\/p>\n
Leigh Day, the firm acting for the fishery, is experienced in public law challenges to regulators and has a record of bringing habitat\u2011protection and abstraction cases. The firm\u2019s public profile confirms its capacity to issue pre\u2011action letters and, if necessary, pursue judicial review against bodies such as the Environment Agency\u2014steps the fishery has now signalled it is prepared to take. <\/p>\n
The Environment Agency, for its part, has been operating in what it describes as an exceptionally dry spring. In a June blog the agency outlined measures taken to support farming and manage scarce resources, describing the legal framework for abstraction, the role of the National Drought Group and the practical challenge of balancing ecological needs with public water supply and agricultural demand. That account provides context to the agency\u2019s decisions over licensed abstractions but does not directly address the club\u2019s allegation; the regulator has not answered detailed questions while the matter is in the hands of lawyers. <\/p>\n
If the dispute proceeds to judicial review, it will test how the regulator interprets and applies its obligations where designated habitats and ecologically sensitive species are concerned. Conservation bodies and site designations impose legal duties to safeguard ecological flows and habitats, while the agency must also weigh wider public interests during drought\u2014including support for farming and water supply\u2014making any court examination likely to focus on how those competing duties were balanced in practice. <\/p>\n
For now, the immediate course is procedural: the pre\u2011action letter sets a short deadline for remedial steps or meaningful engagement before formal proceedings begin. Should talks fail, the club says it will move to court to force restoration of flows and seek judicial scrutiny of the regulator\u2019s conduct. Both sides have signalled what is at stake\u2014the future of a rare breeding trout population, the integrity of protected waters, and the standards by which a regulator manages scarce river resources in extreme weather. <\/p>\n
