The River Aire is 71 miles (114 km) long, running from Malham to Airmyn
The river runs through 5 conurbations – Skipton, Keighley, Bradford, Leeds, Castleford – whose population is ca. 1.5 million, all of whose sewage effluent is treated by Yorkshire Water and subsequently discharged into the river
The River Aire has 4 major tributaries (depending on your definition of ‘major’!) – Eller Beck (Skipton), River Worth (Keighley), Bradford Beck (Bradford), River Calder (Halifax & Huddersfield)
At Beal, which is the furthest downstream gauging station, the Q95/Dry Weather Flow of the River Aire is 8.1 m3s-1 (that would take 5 minutes to fill the apocryphal Olympic swimming pool), the highest flow ever recorded was 294.8 m3s-1 (8 seconds!) on 7th November 2000.
The river drains an area of square kilometres ( acres in ‘old money’)
It drains several local authority areas – Pendle, Craven, Bradford, Leeds, Wakefield, Selby?, East Riding?
The heaviest fish recorded as being caught in the River Aire is the 22lb 8oz (10.20 kg) pike caught by R Preston of Skipton Angling Club in 2005.
There are 84 barriers to fish passage on the River Aire – one of our key areas of activity is working with landowners and the EA to remove them or, where that is not possible, to install fish passes.
In 1733 it was stated that the Aire at Keighley “affords Dares, Gralings, Menards, Bonestrickles, Pearch, Eels, Gudgeons, Ruff, Chub, Trout, Salmon and Salmon-Smelts: The former, when out of season, come up the river to spawn, and return into the salt water again. There is plenty of Millers Thumb and Pike, which the River was first stored with by Mr Tempest’s Fish Pond of Broughton, breaking into the River”.
