title: River Gipping
context: The River Gipping is the source river for the River Orwell in the county of Suffolk in East Anglia, England, which is named from the village of Gipping, and which gave its name to the former Gipping Rural District.  The name is unrelated to the name of Ipswich.[1] It rises near Mendlesham Green and flows in a south-westerly direction to reach Stowmarket. From there it flows towards the south or south east, passing through Needham Market and a number of villages to reach Ipswich, where it becomes the Orwell. The river has supplied power to a number of watermills, several of which are still standing. None are operational, although the mill at Baylham retains most of its machinery, and is the only complete mill on the river.
