About the River Gade

River Gade

The River Gade is a chalk stream running almost entirely through Hertfordshire. It rises from a spring in the chalk of the Chiltern Hills at Dagnall, Buckinghamshire 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. For its whole course the Gade is unnavigable, with the exception of a short section in Apsley, Hertfordshire where. it forms a section of the Grand Union Canal.
