Snowmaking 101

Man-made snow is produced by combining compressed air and water using machines called snow guns, which cool and atomize the water while blowing it into the air where it crystallizes to form snow. The snow's density can be adjusted by changing the air/water mixture to produce heavier snow for base layers or lighter snow for groomed runs.

Big Bear Mountain Resort purchases water for snowmaking from the Big Bear Municipal Water District (WMD). The amount of water used for snowmaking equates to approximately 4 inches of surface water, with nearly 90 percent returning to the lake via ground absorption and runoff waterways. For comparison, Big Bear Lake averages 1-2 feet of natural evaporation during the summer.
