The North Forty Foot Bank is an area in the civil parish of Holland Fen with Brothertoft, in the Boston district, in the county of Lincolnshire, England. It runs about 6 miles (10 km) along the North Forty Foot Drain, about five to nine miles north-west of Boston. It begins just south of the parish of Chapel Hill and runs along the drain to Toft Tunnel, just north of Hubberts Bridge. Despite its length, it only consists of the area on the north side of the drain, which was built in 1720 by Earl Fitzwilliam. The North Forty Foot Bank forms the boundary between Harts Grounds and Pelhams Lands.

The nearest watercourse on the river map is the River Witham, about 80 m from the middle of Hedgehog Bridge's gauges. It flows into the Haven about 7.2 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Witham nearest the middle of Hedgehog Bridge's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
