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.

The Tuloma belongs to the Teno-Näätämö-Paatsjoki River Basin District. 4 The Upper Tuloma Reservoir was built 1963–1965, with an installed capacity of 50 MW and a total volume of 11.52 × 109 m3 (effective volume 3.86 × 109 m3). The Lower Tuloma Reservoir was built in 1936 with an installed capacity of 228 MW and a total volume of 390 × 106 m3 (effective volume 37.2 × 106 m3).
