Big Bear Lake, United States

Big Bear Lake is a reservoir in the western United States, located in the San Bernardino Mountains in San Bernardino County, California. It is a snow and rain-fed lake, having no other means of tributaries or mechanical replenishment.

At a surface elevation of 6,743 ft (2,055 m) above sea level, it has an east-west length of approximately seven miles (11 km) and is approximately 2.5 miles (4.0 km) at its widest measurement, though the lake's width mostly averages a little more than 1⁄2 mi (0.8 km). These approximations are based on the lake having an optimum retainable water level. At dam's end, Big Bear measures its deepest water at 72 feet (22 m).
