The River Humber from Ferriby Sluice, Lincolnshire
The River Ancholme enters the River Humber, which forms the boundary between Lincolnshire and Yorkshire, through a sluice completed in 1844 by Sir John Rennie at the appropriately named hamlet of Ferriby Sluice just outside South Ferriby. This shot was taken approaching slack water with the sluice gates slightly ajar to regulate the water level in the marina on the River Ancholme, a river which has long been used as a navigation and drainage channel. There are records of improvements to the river as early as the thirteenth century. The river runs in two channels known as the "Old River Ancholme" and the "New River Ancholme", the later being the result a local landowner cutting a straight drainage channel in 1635 to help take the waters of numerous becks out to the River Humber whilst the old "Old River Ancholme" follows it's natural course.
