Here is Wednesday morning’s installment of our update on the Oroville Dam spillway incident and more news about the valley. For background, please see our earlier blog posts which set the stage and provide context. In sum, the mandatory evacuation is over; the emergency or auxiliary spillway remains stable; workers continue to add rock and concrete to address the erosion that led to the evacuations; the primary or service spillway is also stable, and is still evacuating 100,000 cfs from the reservoir; but new storms are forecasted to roll in starting Wednesday evening.
Because there is less news today, we have tried to provide some information on the weather and flood system operations.

Here is Tuesday morning’s installment of our update on the Oroville Dam spillway incident. For background, please see our earlier blog posts, starting last Thursday, February 9, and most recently our update of
What a difference a day makes! As of Friday afternoon, it appeared unlikely that Oroville Reservoir would rise enough for water to flow over the emergency spillway, as inflow into the lake had been declining since early Friday, the rain had stopped, and the primary spillway continued to be used to manage outflow. But the gaping hole in the spillway, coupled with concerns about downstream flooding, resulted in the story traveling all the way back to
As many of you know, the big news on Tuesday was that the spillway on Oroville Dam had developed a large crater from water eroding away the Oroville Spillway structure. Based on the large hole, DWR stopped all flows down the Spillway to evaluate the damage. Water users downstream started to get nervous as Oroville was rising quickly, and folks feared that water could come over the emergency spillway, which would be uncontrolled.
This is a follow-up to our blog post last week, “

People definitely care. But not enough people are likely to care to make a political issue out of it due to how the rate increases were designed. The National Flood Insurance Program (NFIP) rate increases called for by the last two acts of Congress are designed as slow and modest increases for the vast majority of folks holding policies. Indeed, this appears to be the reason Congress passed the Homeowner Flood Insurance Affordability Act of 2014 (HFIAA), in order to amend and soften the rate increases called for by the Biggert-Waters Flood Insurance Reform Act of 2012. During this current election year it takes a lot to get Congress focused on action, and the rate increases do not appear to fall on a large enough group to generate the noise that gets Congress’ attention. Added to that, the Republican Party is currently focused on demonstrating fiscal restraint, and rate increases designed to repay an approximately $20 billion deficit fit right into the current messaging.
