Surveillance Video Shows Dam Vandalized, 50 Million Gallons Of Water Lost

FREMONT (CBS SF) -- Fremont police hope surveillance video will help them find three men suspected of vandalizing a dam, wasted millions of gallons of water in the process.

The newly-released surveillance footage shows the men entering a restricted area of Alameda Creek and intentionally damaging an inflatable dam.

The dam is used in the Alameda County Water District's operations to recharge the Niles Cone Groundwater Basin, one of the district's main water supplies.

The damage sent an estimated 50 million gallons of water -- enough to supply nearly 500 homes for one year -- rushing down the creek. The dam will cost $3 million to replace.
