Whispering through the heart of London Dollis Brook meanders. A small stream it is yet its story is vast. From its source near Moat Mount Open Space in Mill Hill Dollis Brook flows. It journeys eastwards through Totteridge Fields. It passes through open spaces towards King George V Playing Fields.
Dollis Brook’s name hints at a rich past. It likely derives from the Middle English word ‘dole’ meaning land shares in a common field. This suggests a time when the land surrounding the brook was communally farmed. Imagine the farmers sharing their harvests near this very spot.
The brook continues its southward journey. It forms Totteridge’s eastern boundary. It flows through Wyatts Farm Open Space and Brook Farm Open Space. It passes near Totteridge and Whetstone Underground station. The brook then merges with Folly Brook in Woodside Park. It continues through West Finchley.
Underneath Dollis Brook flows the Northern Line. The Dollis Brook Viaduct carries the trains. This impressive structure is the highest point of the London Underground above ground level. It reaches almost 60 feet high. Built in 1867 it was once part of the Edgware Highgate and London Railway.
Until 1965 Dollis Brook marked the boundary between Finchley and Hendon. Today it flows under Dollis Road. It passes through Windsor Open Space. Finally it joins Mutton Brook near Bridge Lane in Hendon. Together they form the River Brent a tributary of the mighty River Thames.
The Dollis Brook is more than just a waterway. It is a haven for wildlife. Kingfishers grey wagtails and moorhens can be seen here. Aquatic plants like yellow iris and water-pepper thrive along its banks. Sadly a sewage spill in 2012 caused harm. Thames Water pump failure resulted in a terrible stench and dead fish.
The Dollis Valley Greenwalk follows much of Dollis Brook’s course. This is a wonderful way to appreciate the brook’s beauty. It allows you to appreciate the nature it supports. The London Loop path also follows parts of the brook. These paths let you experience this often-overlooked treasure of North London. So take a moment to appreciate Dollis Brook. Notice its quiet beauty its history and its importance to the local ecosystem.
