Why the state wants to lower Lake Gregory's water level
After years of study, San Bernardino County officials have been ordered to lower Lake Gregory in Crestline to relieve pressure on its seismically unfit, nearly 80-year-old earthen dam.
The state Division of Safety of Dams, a unit of the California Department of Water Resources, has ordered the county to lower the dam level by 2 to 3 feet by Jan. 1.
The lowering is part of a larger plan to retrofit the dam, potentially protecting campers, hikers and county property, including roads, from a potential breach following a major earthquake in that area, state and county officials said.
The buttressing of the dam will cost $8 million, said David Wert, a county spokesman.
