February 14, 20179 yr Maybe if Calif spent as much money on the dam as they did for protecting illegal immigrants they wouldnt have that problem.
February 18, 20179 yr Author Video from today, the Emergency Spillway has again been topped with the recent weather. https://www.youtube.com/watch?v=6vbn2bR1JvU Also, tweet of picture of main spillway damage that seems to have gotten a worker fired. Twitter

February 19, 20179 yr A little humor for the serious situation in California. The dam is only part of the broader flooding problems. "Anyone seen a fire truck...I parked it right here." (on the side of the interstate.) Twitter This bring up a bigger issue with the spillway. The ground their isnt used to handling any water of any kind. When you put mass amounts of water on it, what did they expect to happen.
February 21, 20179 yr Author Issues are broad and wide in NorCal. I just got off phone with client and co-workers in the Silicon Valley area. 101 between San Jose and SFO closed due to flooding. Trains have not run for over a week due to high water. WeatherChannel showing rescues in San Jose right now. And yes, they have their eye on Oraville - though it probably would not directly impact them at that end of the Bay area. In 2008 I went out 3 weeks out of every month to the Bay area for 7 months straight. Never a drop of rain during that time. Wild weather still going on out there.

You think this is the softening up before the big quake?
February 21, 20179 yr Author You think this is the softening up before the big quake? Well, current EQ prediction app from SuspiciousObservers shows California coast in medium risk for 6+. This is more due to solar wind from coronal hole facing Earth right now. But the water can cause its own seismic activity. Interesting link here: Dams & Earthquakes – Seismology Research Centre Large new reservoirs can trigger earthquakes. This is due to either: change in stress because of the weight of water, or more commonly by increased groundwater pore pressure decreasing the effective strength of the rock under the reservoir. For triggered earthquakes to occur, both mechanisms require that the area is already under considerable tectonic stress. Reservoir triggered earthquakes are often referred to as reservoir induced seismicity (RIS), but use of the term “induced” is now becoming unfashionable. To many people it implies that the reservoir caused the earthquake. The energy released in a reservoir triggered earthquake is normal tectonic strain energy that has been prematurely released because of the reservoir.

February 22, 20179 yr California's Great Flood of 1862. Repeat? California Megaflood: Lessons from a Forgotten Catastrophe - Scientific American NYTimes - from 1862. THE GREAT FLOOD IN CALIFORNIA. - Great Destruction of Property Damage $1�,���,���. - NYTimes.com The Pacific slope has been visited by the most disastrous flood that has occurred since its settlement by white men. From Sacramento northward to the Columbia River, in California, Nevada Territory, and Oregon, all the streams have risen to a great height, flooded the valleys, [inundated towns, swept away mills, dams, flumes, houses, fences, domestic animals, ruined fields and effected damage, estimated at $10,000,000. All Sacramento City, save a small part of one street, part of Marysville, part of Santa Rosa, part of Auburn, part of Sonora, part of Nevada, and part of Napa, not to speak of less important towns, were under water. "White men...less important towns...". They were not too PC in 1862... More... The flood entered at the East, where the land is high, and if the levee had not been in the way, the water would have run off without touching the business part of the City. The Sacramento River was much lower, its flood had not had time to come down, so there was abundant room for the water of the American to spread out when it should reach the Sacramento River. But the levee dammed the water in, and it very soon was ten feet higher inside than the level of the Sacramento River on the outside. In some places the water was fifteen feet deep, in others ten, in others three. The greater part of the most fashionable houses had from three to six feet of water in the parlor. In many of the houses the line of the flood is visible on the plastering in the second story. Dozens of wooden houses, some of them two stories high, were lifted up and carried off. The destruction of property was terrible. The water came so rapidly that most people had not more than an hour's warning of the danger. Most persons living in two-story houses carried their furniture and cooking utensils and provisions up stairs; [???] who lived in one-story houses ran for their lives. And when the water filled the city there were no boats, Men, women, and children had stayed in houses thinking there was no danger; and when the flood rose they could not get away. Some of these houses were carried off, and boats were sent after them to rescue the human freight. Wow, very interesting on the 1861-62 floods, I had never heard or read about that. I lived in central CA from January of 1985 till late August of 1988 while stationed at Ft. Ord during my time in the Army. Ft. Ord (since decommissioned) was just south of San Francisco. Though not a "hot" area by any stretch, it's definitely dry. The rainy season there is from Dec till about Feb. What rainfall does occur usually happens in those 3 months. And it's usually not a lot, and the time I spent there I saw little rainfall. I'll bet in the 3+ years I was there, I saw less rain than we will here in a typical "wet" spring in one year.
February 22, 20179 yr Author This guy gives a really good report - total of 17 minutes. If you want to skip the 'classroom' session skip to the the 7:10 mark and he gives a walking tour of the dam and situation with some really good video. [video=youtube;Nrz-U1yxOWM]
February 22, 20179 yr Author Another somewhat gloomy/doomy article on situation that plays back to the 1862 floods. Every 2
February 22, 20179 yr Good Video by that guy. Like I said before, I think the lack of rain for years helped cause this problem, but as long as the main dam is holding, they should be able to correct all this when it dries up.
