2017 – An important year for River Aire fish passage

Work has been going on for a number of years to improve fish passage for migratory fish in the Aire below Leeds. This work has provided fish passes at Castleford, Lemonroyd, Fleet, Rothwell Country Park and Thwaite Mills.

Fish passes are required on a further four weirs downstream of Leeds. All the four weirs are owned by the Canal and River Trust and are used for navigational purposes. Three of the four weirs are major ones and are situated at Chapel Haddlesey, Knottingley and Knostrop. The other weir, which is not quite as big a barrier to fish as the others, is at Crown Point in the centre of Leeds.

Major developments are currently taking place which will provide fish passes on all four of the weirs mentioned above. Two of the weirs will be furnished with fish passes as a result of hydro electricity schemes whereas the other two are included as part of the Leeds Flood Alleviation Scheme (Leeds FAS) and will receive fish passes as the weirs are rebuilt. The time scale for completion and brief background notes are shown below. The result of these developments will be that migratory fish such as salmon, sea trout and eels should be able to reach the centre of Leeds with relative ease by September 2017.

Chapel Haddlesey

This weir is at the tidal limit and was first constructed in 1702. UK Hydro Ltd started work in August 2016 on two Archimedes Screws, a fish pass and a by-wash channel. The screws are already installed and work has begun on the fish pass. The fish pass is expected to be in use by fish at some point in March 2017.

Knottingley

This is the biggest weir on the River Aire being some ten feet high. The weir was reconstructed in the 1970s.

In the summer of 2016, Barn Energy commenced construction of a Kaplan Turbo and fish pass on the weir. Power generation is expected to start in the late summer of 2017 and the fish pass should be in use by the end of September 2017.

Knostrop (Leeds)

Knostrop Weir, substantially rebuilt in 1905, has already been removed and replaced by a temporary weir. The weir is being rebuilt as a moveable weir as part of the Leeds Flood Alleviation Scheme and the new weir will include a fish pass. The work is expected to be complete by May 2017.

Crown Point (Leeds)

The weir at Crown Point has already been substantially demolished under the Leeds Flood Alleviation Scheme. The weir is being rebuilt as a moveable weir and will include a fish pass. Work should be complete by July 2017.

In the longer term we continue to develop and seek funds for our DNAire project to remove all barriers to passage on the main spine of the river and enable a sustainable population of migratory fish.

Thanks to Kevin Sunderland for writing this article and his undying enthusiasm and passion for getting salmon back to Skipton and beyond – his dream is beginning to look real,

Chapel Haddlesey update

Work on the weir at Chapel Haddlesey continues apace with some serious excavations adjacent to the weir. At the bottom of this post is an update from UK Hydro, the company which is building the hydro and fish pass on Chapel Haddlesey (CH) Weir. The weir is the bottom weir on the River Aire and… Continue Reading

DNAire bid submitted

Last week, the Environment Agency submitted our DNAire bid to the Heritage Lottery Fund. This is a very important step in our desire to restore salmon to the river and re-engage the community through a £4 million river-wide project. The bid summary states: ‘Developing the Natural Aire’ is for 570,000 people in the project area.… Continue Reading

Eastburn Beck improvements

Eastburn Beck is to be made better for fish and wildlife in general as a result of a joint project between The Aire Rivers Trust, The Wild Trout Trust, The Environment Agency and ABP Green Port Hull. This project will make it easier for fish to get past two key weirs along Eastburn Beck at… Continue Reading

River AIre Fact File

Just found this archive document produced by the Environment Agency “River Aire Fact File”. It is a little out of date – not quite sure how old – but very interesting all the same as not much has changed since it was produced and the base data about the river and its catchment is still… Continue Reading

Improving Eastburn Beck

We are pleased to announce a partnership with The Yorkshire Wildlife Trust, The Wild Trout Trust and the Environment Agency to improve Eastburn Beck. At the Trust meeting on 3rd December 2015, we agreed to make an initial small donation to support work to exclude cattle by fencing the beck off. This will complement other… Continue Reading

Salmon at Newlay Weir

  Kevin Sunderland has captured some encouraging photos of salmon haveng a go at Newlay Weir. These are almost certainly one of a few fish that probably get up the lower weirs under flood conditions and are hugely encouraging for the current condition and the future of the river. This is what Kevin had to… Continue Reading

Eller Beck culverting

A new culvert is being installed on Eller Beck as part of the Skipton flood alleviation scheme. Baffles on the base of the culvert will keep water deep enough for fish to swim through. They will also hold some gravel and natural bed material which will also ease fish passage. The EA have also provided… Continue Reading
