Silk Stream is just over 4 kilometres long and lies entirely within the current London Borough of Barnet.
The name is believed to derive from Sulh or Sulc, the Old English for plough or furrow.
The Silk Stream winds from the area near to Edgware Hospital and flows into the Welsh Harp. Silk Stream is a tributary of the River Brent. Its own main tributary - Burnt Oak Brook - runs for about 1.5 kilometres from near the M1 motorway and meets the Silk Stream at Burnt Oak. It has several other tributaries including Edgware Brook, the Edgwarebury Brook and Deans Brook.
