The
River Tolka (; , "the flood") is one of
Dublin's three main
rivers, flowing from
County Meath to
Fingal, within the old
County Dublin, and through the north of
Dublin city,
Ireland (the other main rivers are the
Liffey and the
Dodder). By flow of water, the Tolka is the second largest river in Dublin, following the Liffey, but runs more slowly than the Dodder.
