The lake was formed by the construction of a 90-meter-high concrete dam, which was one of the highest in Europe at the time of completion.
Under the water lie the remains of the old village of Borgo San Pietro, which was relocated to the hillside before the valley was flooded.
The hydraulic connection between Lago del Salto and Lago del Turano allows water to be pumped between the two basins to optimize hydroelectric output.
The reservoir reaches a maximum depth of approximately 80 meters near the main dam structure.
The lake is a popular site for carp fishing, with annual local tournaments organized by regional angling associations.
Lago del Salto is the largest artificial reservoir in the Lazio region, created in 1940 by damming the Salto river. It features a distinctive fjord-like shape with narrow, winding branches stretching through the Cicolano mountain district. The lake is connected to the neighboring Lago del Turano via a subterranean hydraulic tunnel system that supports hydroelectric power generation. Water levels fluctuate significantly depending on energy demands and seasonal rainfall. The surrounding topography consists of steep limestone ridges covered in Mediterranean scrub and deciduous forest. The reservoir is a primary destination for recreational sports including swimming, windsurfing, and sport fishing for pike and perch. Several small, elevated villages such as Borgo San Pietro and Fiumata overlook the water, offering panoramic vantage points. The lake's creation resulted in the submergence of several original village sites, which remain at the bottom of the basin.

Bring water shoes, as the shoreline consists of rocky and pebbly patches rather than soft sand.
Check local weather reports specifically for the Rieti mountain area, as conditions shift rapidly compared to the nearby Roman lowlands.
Visit during weekdays to avoid peak summer crowds when lakeside beaches reach high capacity.
Attempting to swim near the hydroelectric dam structure, as currents and suction hazards are present.
Respect private property signs near lakeside residential areas and adhere to regional fishing permit regulations.
