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 16,000 inhabitants.
The additional spillway is set after the normal drain it went. By the severe rainfall of the last days increased the water level of Lake Oroville to a dangerous height. Saturday was a zinkgat in the middle of the spillway. The erosion caused large pieces of concrete were swept away by the water and the hole just kept growing. Engineers therefore decided that a second (emergency)spillway to open all of the water to carry away.
For the first time in the history of the dam there was an extra waterway is opened. Also this was quickly the large volumes of water and erosion by ensuring that the waterway is on the verge of 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 hrs (1.30 pm Dutch time) to know that the drain is expected to become “within an hour go”.
