A section from the extinct waterway of the Little Ouse to the former Red Mere in west Suffolk is described, which shows that the lake mans succeed the clay flanges extending from the roddon silts. Thus the Fenland Meres formed in the course of the Coastal or Upper Silts transgression of the Fenland Basin, during which raised banks of silt were built along the tidal waterways, and these ponded back the fresh water. The Meres are shown to be roughly similar in age and manner of formation to the Norfolk Broads.
