CNN双语新闻(翻译+字幕+讲解):灾上加灾 继火灾后美国加州再面临洪灾威胁

We’ve done some reporting lately on the destructive wildfires in
California. The state’s still in the midst of its fire season when
blazes are more likely to flare up, but the major wildfires we’ve told
you about have been contained for the most part. Now though, some
people in Southern California are in danger of another potential
disaster — flooding. The U.S. Army Corps of Engineers which operates
and maintains about 700 dams in America recently issued a new warning
about the Mojave River Dam. It’s located at the northern side of the
San Bernardino Mountains and last year the Corps ran a risk assessment
of it, and concluded that if water flows over the top of the dam
during an extreme flood event, the dam could fail. To be clear, the
Corps says the kind of flooding that could cause that is unlikely and
it’s never happened before. But it’s drawing attention to the issue
because the area expects more rain this winter. And if the dam were to
fail, flooding could effect more than 315,000 people who live in
nearby communities about 70 miles northeast of Los Angeles. The Mojave
River Dam was built in 1971. That makes it younger than most of the
dams across the U.S. There are more than 90,000 of them and most are
more than 50 years old. They help provide irrigation and hydropower
and protect communities from flooding. But many across the country are
under review and the importance of assessing them became clear in 2017
when the Oroville Dam in northern California was damaged after heavy
rainfall. That led to the evacuation of 180,000 people before water
levels at the dam dropped. Four years ago the Army Corps of Engineers
estimated it would need $24 billion to fix all the dams that needed
repairs.
