Lock Gates at Anton's Gowt

This particular 'Gowt' runs into the river Witham just above Boston.

Anton refers to Sir Anthony Thomas, one of a group of people who helped drain the Witham Fens from 1631 onwards.

A 'Gowt' is a water-pipe under the ground. A sewer. A flood-gate, through which the marsh-water runs from the reens into the sea."

A 'reen' is a drainage ditch, or canal, used to turn areas of wetland at around sea level into useful pasture.
