The new way of dealing with failing and neglected infrastructure.
All eyes were on the reopening of the damaged spillway at Oroville Dam . It is only able to release water at 1/3 of the designed flow. The dam engineers have lost the ability to reduce the flow to any thing less than 45,000 cfs because it will erode the upper undamaged spillway. Any more and it cuts into the mountain towards the main dam.

The hope is that the inflow doesn't overwhelm the ability to outflow.
The diversion dam redirects water from the Sacramento River in Redding underneath the city and down to Anderson and Cottonwood.
It's a design that's held tried and true for almost 100 years, until now.
Maintenance supervisor for the Anderson Cottonwood Irrigation District Randy Davis says the damage done to the diversion dam is beyond anything he and his team can handle.
“I've been here 36 years, and this is about 100 percent worse than anything I've seen in the past,” Davis said. “And we just, our maintenance crew is just not setup to do that much work.”
“My concern right now is erosion,” Foster said. “We have 100-year-old oak trees lying in the river. Everything that was there, old growth that protected the banks, it was just sucked in. … This is all going to go under water and it’s all freshly slipped material. This is all going to start eroding. We don’t know if it’s going to take the banks. … The river could actually start a new channel.”
… Foster said a 300-foot buffer zone of bluffs, trees and vegetation protecting his walnut orchard was wiped out and now the orchard sits in the path of future rising waters. Debris turned the river brown.
“I’ve never seen it so dirty in my life,” he said.
I saw this but couldn't find the details of the concrete spray.
"Get out of our way" said the engineers.
I should not be so harsh, my NY Governor is just as big if not a bigger Moonbat.
Wade Crowfoot, a former advisor to Gov. Jerry Brown who now leads the Water Foundation, a nonprofit research organization in Sacramento, compared the situation to the state’s years-long drought.
“This is a wake-up call,” he said. “ The drought reminded us we need to use water more wisely. Oroville reminds us that we need to upgrade our infrastructure and our management to move water more wisely.”
Brilliant........ May be he could remind us to drink when thirsty.
Sunday's request by Governor Brown follows three other separate Presidential major Disaster Declaration requests that were granted last month and last week , to support response efforts for the situation at the Oroville Dam, and impacts of the early and late January storm systems.
