PacifiCorp plans to draw down the water even further starting Monday, to get a better look at the damaged area. How far the water will drop this week is unclear; workers will lower it until they can get a good look at the problem. The drawdown will likely take two to three days.
Looking straight down on the river gives an idea of the natural banks of the river and the depth before this week's drawdown begins. How low it'll go will be determined by the depth workers need to get a good look at the leak.
