Has the Oro emergency spillway upgrade created a viable overflow facility? What megastorm vulnerabilities does Shasta Dam have?

Hi Jim,

Tom Stokely mentioned that Ron Stork may know the answer. Also, found this: https://www.nytimes.com/interactive/2022/08/12/climate/california-rain-storm.html

From the article:

"Yet California officials have downplayed these concerns about the capacity of Oroville’s emergency spillway, which were raised by the Federal Energy Regulatory Commission. Such extreme flows are a “remote” possibility, they argued in a letter last year. Therefore, further upgrades at Oroville aren’t urgently needed.

In a curt reply last month, the commission said this position was “not acceptable.” It gave the state until mid-September to submit a plan for addressing the issue.

The Department of Water Resources told The Times it would continue studying the matter. The Federal Energy Regulatory Commission declined to comment."
