The lake occupies the former site of a gypsum quarry that was flooded to create the reservoir.
The Rio Sass canyon, which connects to the lake, is known for its narrow, deep rock formations and unique microclimate.
The emerald hue is particularly vivid due to the mineral composition of the water flowing from the Dolomite rocks.
The lake serves as a primary hub for the local 'Sentiero dell'Acqua' (Water Trail) network.
The damming project was initiated to regulate water flow and provide a local recreational asset.
Lago Smeraldo is an artificial reservoir located near the town of Fondo in the Val di Non region of Trentino, Italy. It was created in 1964 following the construction of a dam on the Rio Sass stream. The lake is named for the distinctive emerald green coloration of its water, which is caused by the light-reflecting properties of the surrounding rock and silt. A pedestrian walkway connects the lake directly to the town center of Fondo via the Rio Sass canyon. The surrounding area features a network of paths that facilitate circular walks around the basin. The site is a popular destination for both local recreation and light hiking during the warmer months.

Wear sturdy walking shoes to navigate the trail that connects the lake to the Rio Sass canyon.
Visit the nearby Rio Sass canyon interpretive center before or after your lake walk to understand the geological formation of the area.
Pack a light jacket as the canyon area near the lake remains significantly cooler than the surrounding valley.
Do not attempt to swim in the lake, as it is a reservoir with potentially cold temperatures and submerged infrastructure.
The walking paths around the lake may be inaccessible or icy during winter months due to high altitude.
Maintain noise levels to preserve the quiet environment; keep to marked trails to protect the surrounding geological formations.
