The Aire and Calder Navigation is a historic commercial and leisure waterway stretching approximately 34 miles through Yorkshire, England, running from Leeds eastward to the tidal River Ouse at Goole. Originally improved by Act of Parliament in 1699, the navigation has been continuously upgraded over the centuries, with contributions from legendary engineers including Smeaton, Jessop, Rennie, and Telford. The waterway remains an active commercial route today, carrying freight such as oil, sand, and gravel from the Humber ports, while simultaneously serving as a productive and popular coarse fishing destination. The canal is managed in part by the Canal & River Trust and features 11 locks along its main line. The stretch between Great Heck and Goole — approximately 11 miles — is particularly well-regarded among coarse anglers and is managed for fishing by the Boothferry Aire & Calder Joint Canal Committee (BACJCC), offering around 600 pegs across its length.
