Oroville overflow...







[Image by Justin Sullivan/Getty Images]

[edited for typos] The picture to the left was Lake Oroville in California - one of the state's key water sources - towards the end of 2015. The El Niño storms helped alleviate things early last year. years of 'drought' hadn't helped.



This year things are very different, with more storms expected and the 'wet season' only half done, the main and emergency spillways are coping but damaged; evacuations are ongoing.



Thing is, if you look at the pictures on the BBC, the whole hill beneath the spillway seems to be being eroded away. All sources say the dam is safe...but what about the infill and earthwork, the hill? Updates on Zero Hedge of this "Never-Happened-Before Event" have a lot covered and various videos and pictures of the damage.



Apparently "California spent $25 billion on entitlements for illegals last year, and only budgeted $730 million for water infrastructure. I don't think that is what caused Oroville to fail, but it really is something to consider..." [quote from Jim Stone info from FAIR, 2014]

Overflowing ordure...






The picture (left) is from the DT, another HERE shows before and after shots. Reading the sign you can see what is, in effect, all you need to know about the flood disaster and damage that is currently happening in the north of England. The problem is NOT climate change! The floods are NOT unprecedented and have happened for centuries! In England and the UK it rains a lot; sometimes lots and lots! Sometimes it is snow and the thaw causes the floods; sometimes just heavy rain.  For hundreds of years up until 1997 rivers known for flooding were regularly dredged (as were the Somerset Levels); for places like York, currently flooded from the river Ouse overflowing, there is data from centuries ago: "Systematic flood level readings from 1877 and a wealth of documentary records dating back as far as 1263 AD give the City of York a long and rich history of flood records."... "The inclusion of the extended historical flood record (1263–2000) provides an additional eleven events pre-1800, of which five are greater than the largest event in the period 1800–2000."**



The Environment Agency is not fit for purpose and it's adherence to the crazy "....EU directive which discourages proper dredging has been identified as an issue." [WUWT]. I am sure it is inefficiency and inadequacy from the EA making the problems worse: I am certain they wouldn't be doing this on purpose...would they?
