River Gipping
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. 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.
Guarapiche River
Its origin is in canyon named Puertas de Miraflores in the Turimiquire Range.
Together with it flows into a short body named Caño Francés whose mouth is in the San Juan River shortly before its mouth in the Gulf of Paria. In February 2012 there was an oil spill in the mangrove area at the mouth of the river.
