BREAKING NEWS: CA’s Oroville Spillway Structural Integrity Breached

Updated 2300 Hours PST

INCIDENT SUMMARY

The torrential rains have stopped but not the ill-will effects from the over abundance of it over the once drought-ridden State.

Too much of a good thing has this State reeling from the damage from flash flooding, land and mudslides to today where the secondary spillway at the Lake Oroville Dam has created a much bigger problem.  Too much water flowing quickly over the dam causing management to allow water to flow to a secondary spillway.

That does not sound all that too bad, does it?  It is actually frightening to know that the California Department of Water Resources is using the secondary spillway the first time in its 49-year history.  Due to the extreme fast rising water, it has exposed a breach in its construction and now it is about to fail.  This could spell catastrophic for those downriver, therefore we are today covering news about a mass evacuation in the City of Oroville and Palermo, California.
