2025 Annual Riverfly Summary
Our annual Riverfly Summary is now available on the Riverfly Reports page of our website.
2025 was the first year that we had over 10,000 surveys submitted to our database, which is a fantastic achievement. Have a read of this report for an overview of the brilliant work our Riverfly monitors and co-ordinators put in across the UK last year.
A few examples of what you’ll learn from this summary:
which hubs submitted the most data, and which parts of the country are the most thoroughly monitored.
how much the Riverfly Partnership has grown over the last two decades.
what the ‘average’ Riverfly sample looked like in 2025, and which RMI scores were most frequently found.
where trigger level breaches occurred last year, and what some of the outcomes were when these were reported to the relevant statutory body.
A huge thank you to everyone who helped contribute to this impressive dataset last year.
