River Granta is the name of two of the four tributaries of the
River Cam, although both names are often used synonymously. The
Granta, starts near the village of
Essex flowing north
Audley End House
Audley End House to merge with the other contributary Rhee, which
is also commonly called River Cam, a mile south of Grantchester. From
source to its confluence with the Rhee it is 41.7 kilometres
(25.9 mi) in length.
A further tributary, also known as the Granta, runs 10 mi
(16 km) from south of Haverhill to join the larger Granta south
of Great Shelford. Another minor tributary is
Bourn Brook which has
its source near the village of Eltisley, 10 mi (16 km) west
of Cambridge, running east through Caxton,
Bourn and Toft to join the
Cam at Byron's Pool.
In many maps the river changes its name at the Silver Street Bridge in
Cambridge and is called "Granta" above and "Cam" below it.
In earlier times even the lower part of the Cam was also named the
Granta, but after the name of the Anglo-Saxon town of Grantebrycge had
been modified to Cambridge, the river was renamed to match.
Granta Park are on the river banks of the river
Granta and their names refer to the river itself.
