Osney Mirco-Hydro Scheme Oxford

In June and July 2013 Oxford Archaeology undertook an archaeological watching
brief during the installation of a low head turbine at Osney Lock, Oxford (NGR: SP
50305 05923.
The watching brief observed a succession of deposits of post-medieval made
ground forming an island between Osney lock and the weir controlling the level of
the River Thames. All the deposits date from the late 18th/early 19th century
onwards and were probably laid down during the construction of the first Osney
Lock in 1790 and during subsequent work.
No evidence for the old fishweir associated with Osney Abbey or for any other
earlier water management structures was observed.
As part of the work a photographic record and written description of the weir gates
(“Weir B”) immediately west of the development was undertaken prior to their
replacement.
