For decades, the River Clyde carried a heavy reputation.
Once the industrial heartbeat of Glasgow, it was also one of the most heavily impacted rivers in Scotland. By the late 20th century parts of it were described as “biologically dead”, a river where pollution, habitat loss and industrial pressure had pushed wildlife to the margins. At its lowest point it was even labelled a “zombie river.”
Today, however, that story is no longer fixed in the past. The Clyde is steadily coming back to life.
More than 30 species of fish have now been recorded in its waters. Along its banks, birdlife, insects and plants are re-establishing themselves in spaces once considered beyond recovery, including otters and seals, powerful indicators that the ecosystem is functioning well.
This transformation is not accidental. In part, it stems from the decline of heavily polluting industries in the 1960s and 70s – what some describe as a form of “benign neglect.” Alongside this, decades of environmental improvement, tighter regulation and sustained restoration work have helped support the river’s recovery. Today, that change is also being carefully observed, recorded and shared through projects that are reshaping how people see the river.
A living stretch of river in the heart of Glasgow
Along a 6km stretch from Glasgow Green to Cuningar Loop, the Living River Project is documenting the Clyde’s recovery in real time.
The project tracks wildlife returning and residing in the river and identifies key pressures affecting its recovery. It also highlights a less visible but critical factor: invasive species management, habitat restoration, and long-term ecological monitoring. The result is a growing picture of a river in transition, fragile in places, resilient in others and constantly changing.
“Mon the Fish!”: bringing the river into the classroom
One of the most powerful examples of that connection is the Mon the Fish! initiative, developed as part of the Clyde River Foundation’s wider Clyde in the Classroom programme. The Clyde River Foundation, based at the University of Glasgow, has been working for over 20 years to improve understanding of the river’s ecology while engaging communities in its future. Over 50,000 children have taken part in Clyde in the Classroom over the past two decades.
In 2022, the Living River Project partnered with the Foundation to bring river science directly into primary schools. More than 120 pupils from four local schools took part, caring for brown trout from egg to early life stage. Over six weeks, classrooms were transformed into working hatcheries. The pupils weren’t just observing nature but were now responsible for it. They monitored water temperature, maintained oxygen levels, removed dead eggs, and learned what a healthy river actually requires to sustain life. With support from scientists, they followed the full life cycle of a native species and built a direct connection to the ecosystem outside their classroom walls. At the end of the programme, the young trout were released into the River Clyde.
A river can recover under the right conditions
Improved water quality, stronger environmental protections, and decades of targeted restoration work have all contributed to bringing life back to the river. But recovery is not the same as stability.
A healthy river depends on balance between flow, temperature, oxygen levels, and habitat structure. When that balance shifts, everything connected to it feels the impact. Fish need cool, oxygen-rich water. Invertebrates form the base of the food chain. Birds rely on those populations. Plants stabilise riverbanks and shape the physical environment itself. And all of this depends on one fundamental condition: enough water flowing through the system.
When river levels drop, temperatures rise, oxygen decreases, habitats shrink, and wildlife becomes stressed. For a recovering system like the Clyde, these pressures can quickly reverse progress.
One of the least visible pressures on rivers is abstraction, the removal of water from natural systems to supply homes, businesses, and agriculture. In the UK, significant volumes of water are taken from rivers, particularly during dry periods, often when ecosystems are most vulnerable. It creates a direct but rarely considered link: the water used every day is the same water that sustains rivers like the Clyde. This Water Saving Week, we explored this hidden connection further in collaboration with The Rivers Trust, highlighting how everyday water use directly impacts river health and wildlife

The West Boathouse: restoring a gateway to the Clyde
The Clyde’s story is not only unfolding in the water. On its banks, the newly rejuvenated West Boathouse is part of a wider effort to reconnect people with the river.
Led by Glasgow Build Preservation Trust and completed in 2023, the project repaired and adapted the historic Category B-listed building, improving accessibility and opening it up for wider public use. The restoration is part of a broader ambition to re-engage communities with the Clyde corridor and encourage greater access to the river itself.
In this sense, the boathouse is more than a building. It is a bridge between heritage and future use, between the city and the river, and between people and nature. It sits alongside the Living River Project as part of a shared narrative: a river that is not only recovering ecologically, but being reintroduced into daily life.
A river being watched back to life
A key part of that reintroduction is visibility. Through the Living River Project, anyone can take part in recording wildlife along the Clyde using iNaturalist a free app that uses image recognition and a global community of experts to help identify species.
Each observation contributes to a growing dataset used by researchers, environmental organisations and conservation groups to track biodiversity and monitor change.
This Water Saving Week, the story of the Clyde reminds us that our everyday actions matter. By using water wisely and reducing unnecessary waste, we can help leave more water in our rivers, supporting healthier ecosystems, richer biodiversity, and giving more rivers the chance to come back to life
