Oroville Dam's Green Spot: Innocent Pool Or Big Problem?
 

The failure of the Oroville spillway in February led people to notice a large green spot on Lake Oroville's dam. The spot has been there for years, but the questions remain as to whether it's a sign the dam is leaking.

It’s become known as the “green spot” regardless of the season. It comes and goes, green in the spring, brown in the summer.
