It was the spillway’s first major test after the near disaster in 2017 that led to a $1.1-billion reconstruction project.
The California Department of Water Resources released water from the Oroville Dam's main spillway on Tuesday for the first time since water eroded the structure, pictured in this file photo, and forced evacuations in 2017. gates released more than a million gallons of water down a newly reconstructed concrete spillway on Tuesday for the first time since the infrastructure collapsed two years ago.
The reservoir, a key stockpile of California’s water supply, has risen significantly following several storms in the past month and is currently at 854 feet. Boosted by an extremely wet winter season, the reservoir’s water level was 106% of average for the date on Monday, but was still at only 80% capacity, according to the Department of Water Resources.
That leaves the snowpack at 161% of average statewide and 200% of average for the Monday measurement. Surveyors will return to the Phillips station in May for another measurement. At the height of the snowmelt — especially in wet winters — water district managers conduct daily conference calls to coordinate how much water each expects to release into California’s web of rivers, bypasses, creeks and canals.
