Testing conducted by anglers across rivers in Britain and Wales reveals that over a third of freshwater sites are exceeding phosphate levels, undermining good ecological conditions.
Volunteers from fishing groups are taking this information and pushing for changes in river management. However, the challenges ahead are significant, as noted by fishing trust representatives and fish law advocates.
“Our freshwater ecosystems are in jeopardy, and this is something the public, politicians, and regulators are starting to recognize,” remarked the chief executive of Jamie Cook. “Many anglers have already seen the decline in water quality at their favorite spots.”
“This report highlights the ongoing distress in our rivers and demonstrates that anglers are utilizing data to enhance their knowledge of water pollution issues.”
The study assessed roughly 4,000 samples collected by volunteers between July 2023 and July 2024. Observations and photographs were taken to monitor nitrates, phosphates, ammonia, electrical conductivity, temperature, and turbidity across 76 catchments.
Only about 16% of the rivers in the UK are believed to be in excellent ecological health, with phosphate levels capped at 0.306ppm.
The findings indicate that nearly 34% of the samples gathered by fishing volunteers exceeded this phosphate threshold.
While there’s no set limit for nitrate levels, guidance suggests that concentrations above 5 ppm are excessive in freshwater settings. Alarmingly, 45% of the samples analyzed surpassed this level.
The report shows that pollution isn’t uniformly distributed. In the Medway catchment area, which includes parts of Kent, Surrey, and East Sussex, 100% of sites averaged from eight or more samples annually failed to meet the favorable ecological conditions required by the Water Framework Directive, as established by British law.
Similarly, in the Avon catchment of Warwickshire, 86% of phosphate measurement sites did not satisfy the criteria for good ecological conditions.
Anglers are urging both the government and water companies to take action to enhance water quality.
“It’s encouraging to see the community unite for our advocacy efforts,” said Alex Farker, the Angling Trust’s Head of Campaign and Advocacy. “The report lays bare the persistent health issues of the river and the systemic failures that have hindered necessary governance changes to rejuvenate them.”
The extent of pollution affecting British rivers has become increasingly clear, especially as Labour lawmakers have resisted adding further protections to critical streams. Amendments to the bill were declined by all Labour members involved.
In Hampshire, anglers from the Rivers Test and Itchen have utilized data collected over a year to show how local waters impact waterway contamination.
They have raised concerns over sewage dumping from Fullerton wastewater treatment works. Following protests, Southern Water announced that it would enhance treatment capacity to cut down on sewage runoff.
Anglers from the Royal Tun Bridge Wells Angle Society in Medway conducted analyses of 15 sites, collecting 279 samples which all exceeded phosphate levels associated with good ecological status.
These anglers are pressing environmental agencies to form a joint monitoring group that would bring to light that over 90% of the pollution issues stem from direct discharges and overflow from treatment facilities managed by Southern Water.
More than 50 anglers were involved in monitoring efforts in Warwickshire. Their sampling indicated that 86.4% of regularly tested sites in 2023-24 reported average phosphate levels that fell short of good ecological conditions, a figure notably higher than the national average.
“It may be seen by some that the push for improvements from water companies and environmental agencies is arriving too late. Still, I hope my grandchildren will enjoy rivers that are clean and safe, allowing wildlife and fish populations to thrive once more,” expressed one concerned angler.
