Liverpool's Seven Hills?

[fortinian]

Right WW,
that ran from Moss lake,which was somewhere around Islington,down William Brown st,along Williamson sqr,Whitechapel,through to Paradise st, then into the "pool". The remains of a footbridge over this, were dug up during construction of the Macdonalds building(formerly Horne Bros,etc),which is at the junction of Lord st.

Sorry, you're wrong about the location of the Moss Lake.

The Moss Lake was not near Islington, it was the current site of Crown Street/Abercromby Square. Though it is shown on the map below I believe it is slightly too far south and that the 'Reservoir' was part of the Moss Lake.

I think you might be getting confused with Moss Street which has nothing to do with the Moss Lake.

Picton in one of his Liverpool Geological Society papers says that the Moss Lake Fields had a seasonal* stream running off them towards London Road/William Brown Street called the 'Styrpul'. This Styrpul would join the stream running into the Lyverpul along Paradsise street.

Interestingly the Styrpul could be Anglo-Saxon in origin, 'Styr' (or Stir) meaning agitated water, ideal for describing a fast flowing seasonal stream.

*by seasonal I mean when it was raining during winter and the Moss Lake overflowed the stream would flow more visibly.
