The planned city of Raša (), on the tributary Krapanski Potok of the river in the inner part of the Raška Inlet, was constructed in 1936–1937 as "Arsia" on drained wetlands to gain arable land for farming and to serve expanding coal mining operations, as part of Mussolini's urban colonization and Italianization of Istria. The village of Barban is the other major settlement near the river.
