The River Witham is a predominantly rural catchment that includes Grantham, Lincoln and Boston. In its upper reaches, the Witham 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 drains a network of watercourses in the Fenland area. Internal Drainage Boards play a key role in draining these lower lying areas and maintaining high quality arable land. After reaching Boston, the Witham enters the nationally important conservation area, the Wash, which supports shellfish designated waters. (EA)
