River Penk
The River Penk is a small river flowing though Staffordshire, England. Its course is mainly within South Staffordshire, and it drains most of the northern part of that district, together with some adjoining areas of Cannock Chase, Stafford, Wolverhampton, and Shropshire. It flows into the River Sow, which is a tributary of the River Trent, so its waters flow ultimately into the North Sea via the Humber Estuary.
