Imagine waking up one morning, to find that your home, which you thought was safe, was in fact, is in danger. Not just a little danger, either; but one which could destroy your home, wiping it off the face of the Earth. What do you do?
That’s the situation which has faced almost 200,000 people in Northern California, as the risk of flooding from the Oroville Dam and Reservoir is increasing. An unusually wet winter has led to the reservoir reaching dangerously high levels.
Erosion damaged the primary spillway, as a 200 foot long, 35 foot wide hole formed in the bottom. Closing this spillway merely caused the water to rise even higher, overflowing the emergency spillway.
However, the emergency spillway only had a concrete lip, with the rest of the spillway being nothing more than an open hillside, leading down to the river below. Not capped with concrete, it was subject to erosion, which the water flowing over it quickly caused, raising concerns about the emergency spillway collapsing and releasing a 30 foot tall wall of water on the towns below.
