River Gade
The River Gade is a river running almost entirely through
spring in the chalk of the Chiltern Hills at Dagnall, Buckinghamshire[1] and flows through Hemel Hempstead, Kings Langley, then along the west side of Watford through Cassiobury Park. After passing Croxley Green it reaches Rickmansworth, where it joins the River Colne.[2]
For its whole course the Gade is unnavigable.
Its principal tributary is the River Bulbourne which joins it at Two Waters, just below Hemel Hempstead.
The river was once used to power
water mills, such as those at Water End, Cassiobury Park and Two Waters as well as powering the John Dickinson paper mills at Apsley and Croxley
.
It supported the farming of
new town of Hemel Hempstead
.
Below Hemel Hempstead it runs alongside and sometimes forms part of the Grand Union Canal.
The remains of a Roman villa were found at Gadebridge Park in Hemel Hempstead.
The Gade is one of the rivers referred to in the name of the
Three Rivers district
.
It is home to a wide range of biodiversity, including ducks and a range of insect life.
The river bed from the source at Dagnall to Great Gaddesden, about 3 miles downstream is usually dry. After prolonged rain, it will fill and often flood.
