Manchester's hydraulic system definitely ran from 1894 to 1972.

Wonder of the one in Bristol for the floating harbour and other dock
gates is still operational?

Probably not. Like other systems, the users probably switched to using
their own electrically powered hydraulic pumps in the short term and
where possible to purely electrical drives and many older systems
probably have gone out of use entirely since then.

The Bristol Harbour system was for its own purposes rather than customers
elsewhere, like a power station the schemes that sold hydraulic power had
to run pumps to adequately supply a customer even though they may not
actually need any , at Bristol they would know when a crane was going to be
used a lock operated or a bridge swung.

I visited the International Festival of the Sea at Bristol in 1996 as a
crew member on a visiting vessel and the
Hydraulic system was still in use then, it finally ceased to be used in
2010 which was quite late compared to other installations and the pump
house is now a museum / visitor centre with some space used for small craft
businesses.
