It has been a very dry autumn here in Northern California, with little to no measurable rain here in the northern part of the state since well before Thanksgiving. We should already be halfway through our rainy season here (it generally only rains in California from November to March; the remainder of the months of the year are generally hot and dry).
No media coverage on this at all.
"Hairline cracks" have been discovered in the newly poured concrete in the newly replaced/repaired part of the spillway at Oroville dam (the spillway that failed last February). The information given is that hairline cracks in newly poured concrete are "normal, nothing to worry about". Nobody is mentioning how cavitation (whereby moving water can further excavate cracks). I wonder how often hairline cracks are discovered in the newly poured concrete of things like sidewalks, swimming pools, patios, slabs and home foundations. Not too often I'll wager. Actually, I have never heard of hairline cracks in new construction, that would not be written up by the county inspector.
But, hey, no worries!
The water level in Oroville dam is lower than it has been for years, and will not be getting any higher without appreciable rain. Meaning that the water level is a hundred feet or more below the spillway, and will not spill over the spillway if or until the water level comes up. A lot.
In the meantime, I am looking to perhaps make a move to Southern Oregon (Klamath Falls is on my current "maybe" list). Oroville dam is on the Feather River, and any problems with either the dam or the spillway will release water (maybe a LOT of water) into the Feather River. My house sits behind the levee about one-half mile from the Feather River.
No Climate Change here, though. Nope.
