River Sid
The River Sid is a minor river in East Devon. It flows for southwards from a source in Crowpits Covert at a height of 206 metres above sea level. The source is at the head of a goyle or small ravine.
The underlying geology is impermeable silty mudstones and sandstones of the Triassic Keuper marl, overlain with permeable Greensand and clay-with-flints. The junction between the Greensand and Keuper Marl forms a spring line.
The river flows through Sidbury and Sidford to Sidmouth and is fed by springs flowing from East Hill and water from the Roncombe Stream, the Snod Brook and the Woolbrook. In Sidmouth the river outflows at the Ham through a shingle bar.
The Sid Vale Association, the first Civic Society in Britain, is based in the Sid Vale.
