This could use some surveying - is there a culvert here? Or is this cut off? See also the canal at the end of Taylor Rd - is it connected or not?

Gotta be a culvert here somewhere

What is this a bridge over? Is there a stream here?

Likely culvert under St Helens

Where does this stream go?

This is likely culverted somewhere, needs surveying to find where it connects to the river

This obviously has to go into a culvert and come out somewhere, needs surveying
