Dam failure
In 2017 after the Oroville Dam failure, the Sacramento Bee launched its own investigation on the conditions of 93 dams in California. In the inspection reports from the past five years, Rollins Dam had a not fully operational valve in 2014. The reports showed that the valve opened ~65% in 2014, ~88% in 2015, and in 2017 the NID approved for the replacement of the valve.
