Federal officials have ordered the closure and drainage of the Anderson Reservoir, the main reservoir supplying water to Silicon Valley

usa has tons of smaller dirt wall resevoirs built by local municipalities - so do other countries - and usually a town gets built right under them

an earthquake un-settling the earthen hill is feared to cause an opening in the dam and destroy the town built below it

the dam is (half of) the city water supply


But Valley Water, the agency that manages the Anderson Dam and Reservoir, says it has already lowered the reservoir’s water below the level initially sought by federal officials

there is evidence, however, that the local officials are incappable of the truth so much as to manage the dam to any level whatsoever

2017

The previous riprap washed downstream the last time Anderson Reservoir went over the spillway, during heavy storms in early 2017. The overflow resulted in significant flooding of Coyote Creek and neighborhoods in San Jose downstream from the reservoir.

(the dam was not built to be overflown - the slew and run-arounds are supposed to be working to such effect as to prevent it. but it was over-flown multiply)

images of the main damn overflowing are not found - the images above are of the spillway

this article claims california's dams have been managed by "patch and pray" (although socialism is athiest)

Oroville Dam was badly damaged in 2005 simply by "higher than average rainfall" (coupled with poor management of not keeping the water level to a level safe for seasonal rainfall)

this is part of "patch and pray" from the orville seen above, the scale of the problem of dam mis-management should be obvious

ONE ALSO HAS TO WORRY if "a powerful person" wishes to gain lots of cheap land by threatening the town below or to create a problem in order to get large construction contracts after "wash aways"

the question should be "what river doesn't overflow it's banks occasionally"?

these dirt dams are not built to be over-flown (or shaken when full - earthquake)

but the "standard" for building code is 100 year of weather just for a single family home roof

(what that means is that a damn on a river that can spill enough water to flood should never be a dirt damn - 100 year is no longer the standard if a town is built below it)

and there again - dam builders are often told no town will be below the dam - excusing the dam builders from wider assumptions about catastrophy and outcome

They should build a wall to keep the wetbacks out.
Look how dry it is in the desert where the wall has gone up.
Cause and effect.
You can't beat the MAGA because it is logic based science. Not fake news science.
