The River Witham and its tributaries provide an important land drainage and flood defence function whilst also being valued for their landscape and wildlife. The source of the Witham to the south of Grantham is fed by springs from the Lincolnshire Limestone and supports native crayfish and brown trout. These headwaters gradually give way to a slower moving, heavily modified river that flows through Lincoln and drains a network of watercourses in the Fenland area. After reaching Boston, the Witham enters the nationally important conservation area, the Wash, which supports shellfish designated waters.
