River Ancholme

The River Ancholme winds through northern Lincolnshire, rising near Ingham and flowing east then north to meet the Humber at South Ferriby. It drains a broad flat vale once the bed of a vanished glacial lake, a landscape of rich alluvium and old watercourses. The river has two channels: the straight New Ancholme built in 1635 and the winding Old Ancholme that still loops past Brigg. Near the town’s centre the old channel widens into Island Carr, a surviving wetland pocket. Market towns such as Brigg and villages like Bishopbridge sit close to its banks, linked by bridges and lanes. Archaeology shows the Ancholme has carried boats since at least 800 BC. A sewn-plank logboat found at Brigg in 1888 was dated to that period, its oak planks stitched with moss and caulked. Further prehistoric finds cluster along the valley, from a half-million-year-old hand-axe to Bronze Age settlements and Romano-British sites. The river once carried grain and other goods, and in 1287 a royal patent authorised improvements to keep the channel clear. Later, John Rennie the Elder and his son rebuilt Ferriby Sluice in the early 19th century to control Humber silt. Today the Ancholme is used for leisure boating, rowing, canoeing and fishing. Historic boats are moored at local quays, cared for by the Humber Keel & Sloop Preservation Society. Twelve pumping stations managed by the Ancholme Internal Drainage Board protect the low-lying fields from flooding. The river also supplies water to Scunthorpe Steelworks and the South Humber bank industries through transfer schemes. Old bridges and Ferriby Lock remain protected reminders of the river’s long working life.
