The Swaton Eau river rises to the west and runs through the village until it joins the South Forty-Foot Drain.

Before the draining of the Fens the Swaton Eau was navigable and a large inland port existed close to the current bridge.

Nichola de la Haye, a lady who served as High Sheriff of Lincolnshire for King John, died in Swaton on 20 November 1230.

[1] In 1240 William II Longespée and his wife Idonea, Nichola's granddaughter, applied for and were granted a royal charter to run a Friday market in the village.

This grant was unsuccessfully challenged by residents of Folkingham and Sleaford who feared it would damage their own Saturday and Monday markets.
