LA County flood-control dams at risk of overflowing after recent storms

Flood-control dams in the San Gabriel Valley Foothills at risk of overflowing 02:21

The many dams that prevent flooding in Los Angeles are at risk of overflowing after recent storms unleashed record rainfall totals over the San Gabriel Valley Foothills.

“I live very close to the mountain so in the last month we got a lot of rain,” said Arcadia resident Jin Yang. “I’m kind of worried.”

Sitting just above Yang’s home, on the rolling hillsides of the San Gabriel Mountains, is the 96-year-old Santa Anita Dam. In the past two weeks, the recent rainfall has flooded the near-century old damn with a mixture of mud and debris that goes about eight feet deep.

However, the Santa Anita Dam is not alone.
