plaques set into the ground by the Friends of Bradford's Becks. The first three plaques were unveiled inside and just outside The Broadway shopping centre at the end of 2015, and the rest are to be installed during 2016. The beck runs eastwards from the Bradford moorland and in the vicinity of the cathedral, it meets Bowling Beck and Eastbrook before it turns 90° to the north. After the city centre, there are some open air sections, but the beck is mostly covered over until Queen's Road. Thereafter to Shipley, the beck is largely exposed and accompanied by signage warning of contaminated water. The Friends of Bradford's Becks have amended these signs to take away the negative effect of their warnings as the water is of a better quality now than when the signs were erected in the 1970s. The beck passes underneath the railway lines at the east end of Shipley railway station and the A657 road at the same point and enters the south side of the River Aire at Dockfield in Shipley. The average flow into the River Aire is with one extreme flood event in 1984 recording an outflow of . Ecology and environment In 2009, the Environment Agency classified the beck as being of good chemical, but poor ecological quality. A 2012 survey of the water and its tributaries, found high levels of Phosphates, Ammonia and metals present in the water. Combined Sewer Overflows (CSOs) along the beck and crucially further upstream, allow runoff and pollutants to enter the watercourse particularly in times of high rainfall and flood. A study by the Wild Trout Trust in 2012 noted that the beck was of poor ecological quality in terms of supporting marine life. There are too many weirs and obstacles to prevent trout and other fish to navigate upstream of the beck in its present condition. A trial was held on the beck in 2015 which utilised tampons as detection points for sewage entering the beck. As the tampons do not have optical brighteners, several were left along the beck and then checked under a UV light; those that had absorbed optical brighteners did so from household pollution, which narrowed down where water company officials needed to search for causes of pollution. In April 2019, the Environment Agency re-opened an investigation into a company that had allowed pollution into the beck in August 2018. Whilst the
