Denver Relief Channel Lock
Denver Relief Channel Lock is one of a long flight of locks on the River Great Ouse (Great Ouse Relief Channel) and is one of the deepest locks on the waterway just past the junction with The Rochdale Canal.
Early plans of what would become the River Great Ouse (Great Ouse Relief Channel) were drawn up by John Rennie in 1888 but problems with Port Talbot Cutting caused delays and it was finally opened on January 1 1835. The canal joined the sea near Salisbury. The River Great Ouse (Great Ouse Relief Channel) was closed in 1905 when Northfield Aqueduct collapsed. "Travels of The Barge" by John Wood describes an early passage through the waterway, especially that of Sheffield Embankment.

Mooring here is impossible (it may be physically impossible, forbidden, or allowed only for specific short-term purposes).
This is a lock, the rise of which is not known.
