Lake Corlo is included in the municipality of Arsiè, in the province of Belluno, Feltrino, built in 1954 with the construction of a dam along the Cismon stream. It is named after the Corlo, a small village located near the barrier. The reservoir is elongated and begins downstream of Giaroni di Fonzaso, but the water level is very variable; after the village of Rocca, which rises along the right bank, it narrows further, so much so that it is crossed by two bridges.
Lake Arsiè also has two campsites and a refreshment point.
