By Lindsey McEwen ‘In some cities, more than 70 percent of streams have been paved over. In many cases, city residents don’t even know that there are buried waterways under their feet’ (National Geographic, 2013) The Water City Bristol (WCB) project is working with local people in South Bristol to explore creative engagements with culverted and ‘hidden or forgotten rivers’ in Bristol. ‘Daylighting’ forms one of WCB’s four interweaving strands (along with hidden ecologies, tidal reaches, and care for infrastructure). We have been exploring the background to daylighting debates and talking with local people in Bristol about their relationships with rivers. Here I share a few thoughts and reflections (as a geographer within interests in rivers, water and local ‘communities’). A search of the web indicates that the impetus for daylighting of such lost or hidden culverted rivers has increasing international resonance in sustainable urban design and planning - in settings from Seattle to Seoul. Also of interest to WCB are creative explorations of the relationships (historic, new, evolving) between local people and ‘communities’ with these hidden water courses. For example, their activism has potential to link local people to global movements. The same National Geographic (2013) proclaims ‘Daylighting takes off as cities expose long-buried rivers’ with Saw Mill River, Yonkers, New York ‘being exposed to fresh air after decades of burial’. The language of case studies on the web can be emotive - ‘buried rivers’, ‘hidden gems’, ‘unloved city rivers’... See From Parking lot to Paradise - a 3 minute time accelerated time lapse film of the daylighting processes on the Saw Mill River. Such high profile oft-cited case studies have local people active in campaigning for the release of their local river, with daylighting perceived as ‘breathing life not just into urban streams but also their communities’. See Americanrivers.org ‘Rivers Connect Us’. The WCB team are tracking down a copy of the film ‘Lost Rivers’ (72 mins; Director Caroline Debacle; Icarus films, 2013), which ‘examines hidden waterways in cities around the world and introduces us to people dedicated exploring and exposing them’. This sounds an important film to watch. There is also growing international research interest in daylighting (see daylighting.org.uk), and in creative practices around ‘hidden rivers’ co-generated with local people (e.g. walks tracing above ground the river’s underground route, and storytelling as in Toronto’s Rivers Rising project). The UK Guardian Witness is currently requesting stories and photographs for ‘unloved rivers’ – with the Bristol Frome and Exeter Exe on its pages. In South Bristol, culverted rivers also exist on a smaller scale including the Malago and Colliter’s Brook – both generating renewed interest and community mobilisation to petition for daylighting. While the focus can be on physical deculverting, sometimes ‘lost rivers’ are not actually culverted. They can be above ground but constrained, hidden or neglected (a dumping ground for rubbish). What risks in the mix? What is clear is that among local people, there are a number of different perceived risks within the debate – to daylight or not to daylight. While the positives for daylighting may seem obvious, risks presented against daylighting include health and safety of water courses and fear of local flooding. For example, the flood histories of the south Bristol rivers are distant in the memory of many local people. New residents may have no knowledge or experience of such excesses. The floods of July 1968 inundated Bedminster streets near the Malago and Colliter’s Brook (see Brizzle Born and Bred’s photograph albums Weather Archives and The Great Flood of 1968 on Flikr). The intensifying steep slopes of Bristol make it high risk from surface water flooding, and engineering effort has been placed historically to contain and constrain these rivers. One project that provides alternative approaches to this is the Engineering and Physical Sciences (EPSRC) Blue-Green cities project. This is researching the idea that water planning can involve parts of cities might be ‘green’ and ‘blue’ (or inundated) at different times. That particular project has Newcastle in north-east UK as its case-study. Visiting South Bristol's hidden water courses What is unclear is how the processes and impacts of such daylighting in the UK and further afield is being co-researched and evaluated, and what the role of the arts and humanities might have working alongside geomorphologists, engineers, water managers etc. in these processes. So how do we make space for water in settings with smaller water courses, and how might local people connect to themselves, other people (local, globally) and their place through their connection with their hidden local water course? As well as reading about daylighting, we want to get a sense of the rivers from visiting rivers with local experts. Last Monday afternoon, some of the Water City Bristol team met at Windmill Farm in Bedminster to walk some of the Malago and Colliter’s Brook. Both are tributaries to the Avon and were included in the South Bristol Riverscapes project run by Helen Adshead who has now joined our team. We found the Malago behind Windmill Farm neglected and hidden - entrenched in walls with a load of bricks, bikes and tyres. The water looked clear below but low and managed. What would it look and sound like with more water, more noise, and cleared of its waste? The Malago has a long history of entombment along its lower stretches, with a series of flood relief channels growing ever bigger in response to successive floods in the 18th to 20th centuries. We walked down Clark Street where an old flood interceptor was visible with its weights and chains. The straight section below was cossetted with metal struts. Above the engineering, the river although above ground, was hidden, choked along its line with homogenous Buddleia that had been cut level with the walls. We heard about a community-led Green Capital initiative to enhance this area for walking, and to make it the new front entrance to Windmill Farm. We heard also about the river walks that had connected different river care groups along the Malago during the Bristol Living Rivers project but which no longer take place. We then went to visit the Colliter's Brook - again constrained and hidden by walls - beside Bristol City Football club. We followed its line underground down through Greville Smythe Park down to the River Avon – putting ears to the small water management structures that punctuate the old river course but no sound of the water underneath on that day. Down at the River Avon, the tide was out and the pools and riffles were evident within the deep silt banks. We looked at the outlet from the concrete frame of the efflux of the Colliter's Brook and imagined what it would have like on the 1885-90 Ordnance Survey map when the Colliter’s Brook was depicted as a sinuous wide channel running through a rural estate. Thinking then about further afield in Central Bristol, we reflected on the current state of the River Frome - Bristol’s largest ‘underground river’. In contrast to the smaller rivers of Bedminster, the Frome is a culverted river on a very different scale, hidden from eye in Central Bristol but with its own flood history. The urban part of this ‘lost’ river continues to capture the imagination of both agencies and the public alike. The Multi-story Water project creatively explored local relationships with the Frome with residents in Eastville, while the film The Lost Rivers of Bristol (produced by Weston College students and including Melvin Wood, engineer with the Environment Agency) exchanges its valuable river heritage. More recently, the Environment Agency has been exploring the possibility of working with artists to mark the Frome’s course.

I'm fascinated by the exploration and uncovering of lost watercourses. Seeing this from the perspective of the Cymerau case study area around Borth and Tal-y-bont in West Wales, there is s strong contrast with the fact that here we can see almost every watercourse, trickle or flow. However, due to the recent constant rain, water that should be running through field drainage systems bursts to the surface and flows across roads.

Thanks Shelagh. Good to see you on the Bristol website. Lost, hidden, neglected watercourses - Bristol is really good at that. Andrew Watkinson said he felt the Bristol Avon was one of the most abused urban rivers he had seen! There was a really lovely book or article about this kind of thing - the lost wells type thing. I put it on the community. I will try to find it
