The Tuloma has two transboundary tributaries, the eration. The assessment covers the Oulanka River upstream of Lutto3 and Notta/Girvas, which flow to Lake Notozero (or Upper Lake Paanajärvi. Tuloma Reservoir) in the Russian Federation. The sub-basins of the Petcha and of Lower Tuloma are entirely in Russian territory. The Oulanka River originates in the municipality of Salla in The Tuloma flows from Lake Notozero to the Barents Sea through Finland.
