The lake's water level is artificially managed by the ENEL hydroelectric plant, which diverts water to the Marmore Falls.
It is the only lake in Italy that hosts the Olympic-standard training center for national rowing teams.
The village of Piediluco, located on the northern shore, features a medieval fortress ruin at its highest point.
The lake's name is derived from 'pes de luco', meaning 'foot of the sacred wood', referencing the ancient woods that once covered the surrounding slopes.
Geologically, the lake is a remnant of a much larger body of water known as the Lacus Velinus that covered the Rieti basin in antiquity.
Lago di Piediluco is a natural lake located in the province of Terni, Umbria, serving as the largest natural lake in the region after Lake Trasimeno. The lake is fed primarily by the Velino River, which is the same waterway that forms the nearby Marmore Falls. It functions as an artificial reservoir for the Galleto hydroelectric plant, which creates periodic fluctuations in water levels. The lake is a recognized venue for international rowing competitions due to its calm waters and sheltered basin. Its shoreline is characterized by a mix of wooded slopes and the small, medieval village of Piediluco. The Echo Mountain (Monte Luco) overlooks the lake and is noted for a distinctive echo effect often demonstrated by local boat tour operators.

Rent a small electric boat or pedal boat to explore the quieter, secluded coves along the shoreline.
Walk the narrow streets of the village of Piediluco to find vantage points that are not accessible by car.
Inquire locally about the timing of the water releases for the Marmore Falls, as this affects the lake's current and water volume.
Do not swim in the lake without checking local signage, as water levels can fluctuate rapidly due to hydroelectric operations.
Respect the quiet nature of the village; avoid loud noise near the water's edge where competitive rowing training occurs.
