The lake was formed by the construction of three separate dams: the Sella Pedicate, the Rio Fucino, and the Provvidenza dams.
The reservoir reaches a maximum depth of approximately 30 meters at its deepest points.
It sits within the territory of the Campotosto municipality, which was heavily impacted by the 2009 and 2016 central Italy earthquake sequences.
The local microclimate is significantly cooler than the surrounding Adriatic coast due to the high elevation of the Laga mountains.
The lake is managed by ENEL Green Power for hydroelectric generation purposes.
Lake Campotosto is the largest artificial reservoir in the Abruzzo region of Italy, situated at an altitude of 1,313 meters within the Gran Sasso and Monti della Laga National Park. The reservoir was created in the 1930s by damming the basin of a former peat bog to serve the local hydroelectric power industry. It is surrounded by a scenic road, the SP5, which offers a continuous 40-kilometer perimeter popular for cycling and driving. The water surface frequently freezes during peak winter months, while the surrounding hills are heavily forested with beech trees that turn vibrant colors in autumn. The lake serves as a critical wetland habitat for migratory birds, including various species of grebes and waterfowl. Visitors can access multiple lakeside trails that traverse meadows and woodland areas bordering the shoreline. It remains a key focal point for outdoor recreation in the central Apennines, including sport fishing and windsurfing.

Bring layers even in summer, as temperatures drop rapidly once the sun sets behind the Laga mountains.
The perimeter road is narrow; drive cautiously if towing trailers or driving large recreational vehicles.
Carry polarized sunglasses to reduce glare from the water surface for better visibility of the lake bed and surrounding peaks.
Avoid swimming in the reservoir, as the water temperature remains cold year-round and there are no lifeguard patrols.
Practice leave-no-trace principles, specifically concerning the fragile wetland shoreline and nesting bird habitats.
