Lago del Salto is a reservoir lake in the Province of Rieti, Lazio, Italy. At an elevation of 535 m, its surface area is 10 km².
Lago del Salto was created in 1940 by the damming of the Salto River with the construction of the Salto Dam (Diga del Salto).
The lake is situated in the Apennine Mountains, approximately 40 kilometers northeast of Rome.
The primary inflow of Lago del Salto is the Salto River, which originates in the Monti del Cicolano range. The lake is also fed by several smaller streams and seasonal torrents. The outflow from the lake continues as the Salto River, which eventually merges with the Turano River to form the Velino River.
Lago del Salto has a highly irregular shape with numerous inlets and peninsulas, giving it a distinctive and picturesque appearance.
The maximum depth of the lake is approximately 90 meters.
