San Bernardino is unique among Southern Californian cities because of its wealth of water, which is mostly contained in underground aquifers. A large part of the city is over the Bunker Hill Groundwater Basin, including downtown. This fact accounts for a historically high water table in portions of the city, including at the former Urbita Springs, a lake which no longer exists and is now the site of the Inland Center Mall. Seccombe Lake, named after a former mayor, is a manmade lake at Sierra Way and 5th Street. The San Bernardino Valley Municipal Water District ("Muni") has plans to build two more large, multi-acre lakes north and south of historic downtown in order to reduce groundwater, mitigate the risks of liquefaction in a future earthquake, and sell the valuable water to neighboring agencies.
