The river flows northeast and then curves eastward before joining the Carapelle southwest of Ordona.
With the abolition of feudalism in 1808, Orta became an independent town with Ordona and Carapelle, and, after Italy's unification, in 1863 it received the name of Nova, to distinguish it from two similar-named Italian towns (Orta San Giulio and Orta di Atella).
