Massive evacuation for the impending breakage of the dam in California
Residents in northern California were on Sunday ordered to leave their homes because of an impending rupture of the Oroville Dam. The highest dam in the United States has been damaged by heavy rainfall.
The authorities let you know that a noodoverlaat the any time can fail. The waterway is used to a surplus of water in the reservoir to allow flow.
Without a working noodoverlaat the dam, either fully or partially collapse and large amounts of water can the country enter. To prevent this, with helicopters large rocks in the waterway are thrown, so that holes could be plugged.
People who are in the lower parts of Oroville and in areas downstream, you live, have received a call to “immediately leave”. The local sheriff has the urgent request via other social media spread. It is up to three times emphasizes that this is not an exercise. In Oroville home to over sixteen thousand people. In the total evacuatiegebied is home to more than 160,000 people.
The noodoverlaat was set after the normal drain it went. By the heavy rainfall of the last days increased the water level in Lake Oroville to dangerous height. Saturday was a zinkgat in the middle of the spillway. Erosion caused large pieces of concrete were swept away by the water and that the hole continued to grow. Engineers therefore decided that a second (emergency)spillway to open to allow the water to carry away.
For the first time in the history of the dam there was an extra waterway is open, but also this could be the large quantities of water, causing the waterway to collapse. The high water has ensured that the maximum capacity of Lake Oroville is reached.
The California Department of Water Resources left around 16.30 hours (01.30 pm Dutch time) to know that the drain is expected to become “within an hour go”. At 7.00 pm Dutch time there is again a press conference.
The Oroville Dam is between 1962 and 1968 was built and is 230 meters high. The reservoir is an important water reservoir for the state of California. The dam also functions as protection against floods.
