正文(英文) | Boost for fish migration in Norfolk chalk streamA specially designed fish pass is being installed in a Norfolk chalk stream, to enable fish to swim freely through the upper River Tiffey. The Environment Agency and the Norfolk Rivers Trust’s joint project started in 2019 when a redundant weir near Wymondham Abbey was removed. The weir was causing an obstruction to fish migration. During that phase of work it was discovered that the foundations of nearby Becketswell Bridge were an obstacle for all fish species. So they devised plans to create a fish and eel pass. Once funding was secured for this new phase of the project, work began to install it earlier this year. It is set to be completed in the next couple of weeks. The new pass costing £55,000, is made up of a series of wooden sleepers with notches. They will gently raise the water levels so that fish can swim over the bridge foundations in all conditions. On completion, fish species such as minnow, perch, gudgeon and eel will be able to easily navigate through the upper section of the river. This is a tributary of the River Yare. Amy Prendergast, catchment co-ordinator at the Environment Agency in East Anglia, said:
Ursula Juta from Norfolk Rivers Trust said:
The Environment Agency will continue to monitor and survey the river to measure the effect of the project. Other project partners are the Broadland Catchment Partnership, who contributed some of the funding, and Wymondham Town Council, who will be maintaining the structure. The project is part of the North Norfolk Chalk Stream improvement programme. This builds on the work of the Norfolk Rivers Trust to develop and implement plans for chalk streams across the area. There are only about 200 chalk streams in the world, and 58 of them are in East Anglia. Chalk streams get their pure, clear water from underground chalk aquifers and springs, which then flows across flinty gravel beds. This makes them perfect sources for clean water and ideal for lots of wild creatures to breed and thrive.
