Could Preston’s hidden streams resurface?

In the 18th century several streams flowed above ground from east to west across the Preston landscape. They disappeared underground in the course of the 19th century as they were culverted to provide land for development and to serve as sewers for that development.

Yet they continue to flow below ground today and it is possible to imagine a landscape transformed by opening up some of those streams.

That need not be an idle dream for it is already happening elsewhere. A stretch of the River Sheaf in Sheffield was opened in the city centre earlier this year, an example of โ€˜daylightingโ€™ waterways that Robert Macfarlane mentions in his new book ‘Is a River Alive?’ published this month.

He wrote in an article in the Guardian last week:

In urban planning, โ€œdaylightingโ€ is the practice of bringing rivers back to the surface of towns and cities: unburying them from the dark tunnels in which they have been confined. These entombed watercourses are sometimes known as โ€œghost riversโ€; their voices heard at street level only as prisonersโ€™ whispers drifting from drain grilles.

โ€œDaylightingโ€ is a means of resurrecting river ghosts โ€“ of re-encountering rivers as fellow citizens. In cities where daylighting has occurred โ€“ Seattle, Yonkers, Singapore, San Antonio, many more โ€“ the results have often been transformative.

In Seoul, the Cheonggyecheon Stream was freed from the highway that encased it: the public park created along its banks now draws 90,000 pedestrians on an average day. Summer temperatures at the waterside can be five degrees cooler than surrounding areas, and air pollution levels have dropped by more than a third.

Earlier this year, a long-buried section of Sheffieldโ€™s River Sheaf was disinterred in the city centre to widespread celebration; the result of a long campaign to make the river visible, restored and accessible.

My reconstruction of George Lang’s 1774 plan of Preston showing some of the streams that then flowed above ground, including the Syke and Swill Brook. There were several more watercourses flowing above ground then that are not shown by Lang.

One possible candidate for โ€˜daylightingโ€™ is the Syke, which has its origin to the east of Manchester Road and follows the line of the present Syke Street to cross Winckley Square and reach the Ribble at the bottom of Fishergate Hill.

At the beginning of the 19th century it was still an open stream with water birds such as snipe flying where it flowed through what was to become Winckley Square. At that time, it was still crossed by a bridge near the junction of Fishergate Hill and Broadgate.

Imagine if the hidden Syke was revealed, to provide a babbling brook flowing on the surface once again through the middle of Winckley Square. Its voice can still be heard from underground in nearby Garden Street after heavy rainfall.

An example of what can be achieved is provided by a short stretch of the Swill Brook. This stream formed the boundary between the town of Preston and Fishwick and was almost completely culverted in the 19th century.

It was spared from culverting where it flowed through the grounds of Lark Hill, the present Newman College. When Samuel Horrocks built Lark Hill he utilised the Swill Brook to form the lake that survives in the college grounds.
