What English county does the River Gwash flow through and the village of Litter Casterton reside in?
River Gwash The River Gwash, a tributary of the River Welland, flows through the English counties of Leicestershire, Rutland and Lincolnshire. It rises just outside the village of Knossington in Leicestershire, near the western edge of Rutland. It is about 20 mi long.
Hambleton Peninsula The Hambleton Peninsula lies within the reservoir Rutland Water, in Rutland, England. When the Gwash Valley was dammed in 1975, the area surrounding what was then a ridge were submerged, including a small number of properties in the hamlets of Nether Hambleton and Middle Hambleton. The village of Upper Hambleton survived, and now sits on the peninsula, which is some 3500 metres in length and 1000 metres in width.
