Nearly 200,000 thousand people have been told to leave the area around the Oroville Dam in California, in the US, after heavy rain and snow.

The dam is around 230 metres high and holds back a large lake.

The unusual amount of rain and snow has caused a lot of damage to two parts of the dam that let water escape.
