All Ova is the last culvert of the Sudden Brook before it flows into the River Roch, it's pretty long at 900m and mostly big CMP although not all of it is walkable.

This old culvert built mostly of brick and stone takes the Sudden Brook around 550m through Rochdale.

The River Medlock flows through Manchester City centre taking a meandering route through open air and the Spartacus and Budge culverts.
