The Yorkshire Branch of the IFM is really pleased to be hosting this evening event with two very interesting talks. Speakers from the Don Catchment Rivers Trust and Mott MacDonald will discuss work being done on the Rivers Don and Aire to allow fish passage and to protect them during engineering works.
“Don Catchment Rivers Trust have been working on fish passage on the main river Don since they installed their fish pass at Meadowhall in Sheffield in 2012. Since then the Trust has continued to seek funds and work in partnership to complete another six fish pass solutions, culminating in the opening up of the last remining major barrier on the main Don in 2020 – Masbrough Weir in Rotherham.
Since the first rock ramp was installed in Doncaster by the Environment Agency in 2000, the ‘Salmon to Sheffield’ programme has been characterised by the willingness of several organisations to work together, with the collective aim of re-introducing migrating species back to the river for the first time in 200 years. There are now some encouraging signs that salmon are making it to their first available spawning grounds, although there is always more that is still to be done!”

Leeds City Council (LCC) have commissioned The Leeds Flood Alleviation Scheme (LFAS) to reduce flood risk to infrastructure, residential, commercial and industrial property in areas of Leeds and Bradford along the River Aire in Leeds, West Yorkshire. LCC is proposing to provide protection up to a 1-in-200-year standard of protection including climate change (2039). The Scheme comprises the second phase of LCC’s plans for managing current and future flood risk in the city, following implementation of the first phase (LFAS1) which focused primarily on areas along the River Aire downstream of the Leeds railway station.
Phase 1 of LFAS, extending between Leeds railway station and Thwaite Mills, was completed in 2017. Phase 2 of the Scheme began in 2017, with the aim of providing both the current Phase 1 area and additional areas upstream of Leeds train station with a greater SOP (1 in 200 year plus climate change), without the need for additional construction works inside the Phase 1 area itself.
Phase 2 is split into a two-step approach. Step 1 includes works from Leeds train station to Newlay and provided the area with a 1-in-100 year (1% AEP) SOP. Step 1 received full planning permission in June 2019 and is in the process of discharging planning conditions by zones. Construction works have commenced within several zones, with the first starting in December 2019. Full planning permission for Step 2, works proposed between Apperley Bridge and Calverley, is currently being sought.
Current and proposed works include the installation of linear defences, remediation works to existing walls, construction of a flood storage reservoir at Calverley, strategic placement of scour protection and the installation of flow control structures at three goits (mill races).
Without adequate mitigation, the construction and operation of LFAS2 is likely to have a detrimental impact on fish populations in the River Aire. In order to minimise this impact, mitigation includes embedded design features for fish passage at flow control structures, seasonal timings of in-channel works, development of fish-sensitive construction methods, softening of hard flood defences and installation of floating islands
