The 8.5-acre lake contains 22 million gallons of water with an average depth of 7 feet that slopes from 3.5 feet along Las Vegas Boulevard to 10-12 feet in the center to accommodate the fountain shooters.

The body of water commonly referred to as "Lake Bellagio" in front of the Bellagio Resort in Las Vegas is actually a man-made 8.5-acre lake with a depth of approximately 15 feet. Despite its vast appearance and the power of its 1,214 fountain nozzles (which can shoot water up to 460 feet into the air), the lake is relatively shallow to accommodate the complex network of pipes, pumps, and electrical systems required for the fountain show. However, if you are referring to the real Lake Como in Italy, where the town of Bellagio is located, the depth is significantly more profound. Lake Como is one of the deepest lakes in Europe, reaching a maximum depth of approximately 1,358 feet (414 meters). This geological depth is a result of ancient glacial activity that carved deep trenches into the Italian Alps. So, while the Las Vegas "lake" is a shallow engineering marvel designed for entertainment, the Italian lake that inspired it is a deep, primordial body of water that has fascinated travelers and scientists for centuries.
