The California Department of Water Resources (DWR) reported on May 2 that its Northern Sierra snowpack and water equivalent levels were 188 percent of average.

DWR conducted its fifth and final manual survey at Phillips Station near Sierra-Tahoe, recording a snow depth of 47 inches and a snow water equivalent (SWE) of 27.5 inches. The statewide average snowpack sits at 31 inches of SWE, which is 144 percent of average for this time of year.

The 2019 snowpack peaked on about March 31 and is the fifth largest on record, based on more than 250 manual snow surveys conducted each month. But there is a high probability for new snowfalls over the weekend and later next week.

California’s four northern reservoirs that include Trinity Lake, Lake Shasta, Lake Oroville and Folsom Lake are already at about 93 percent of capacity and rising fast. Hydrologists estimate the April through July snowpack melt and river runoff will be at 158 percent of normal this year.

All of this water should be excellent news to a state that suffered a series of droughts. But California has drastically under-invested in water infrastructure based on predictions that global climate temperature increase would cause the Sierra snowpack to permanently decline by between 48 to 65 percent.

The highly-questionable projections allowed former Gov. Jerry Brown to justify slashing billions of dollars in DWR maintenance funds. Despite campaigning for Californiavoters to approve the $7.5-billion Proposition 1 Water Bond in 2014 and $4-billion Prop 68 Water Bond in 2018, huge amounts of bond funds were siphoned off for environmental boondoggles and none has been spent on above-ground storage to address the state’s cycling between recurring droughts and floods.

The American Society of Civil Engineers awarded California its booby prize in each of the last 3 years as America’s worst state for infrastructure maintenance and improvements. ASCE gave its worst national grade of "D-" for California dams, waterways, and flood control system.

The lack of investment resulted in the 900-foot Oroville Dam almost collapsing during a series of early 2017 El Niño “Pineapple Express" storms that "walloped" the state with as much as five inches of warm rain in a single day. The costs to repair the dam’s main and emergency spillways passed $1.1 billion mark in February, with more work planned.

DWR chief of flood operations John Paasch previously advised, “Along with the water supply benefits of the heavy rain and snow, there is also increased flood risk.”

With the Oroville Dam water height level rising over a foot a day and just 15 feet from overflowing the dam again, DWR and the National Weather Service are closely monitoring weather, reservoir, river, and flood conditions to “help people and communities respond to flood events and stay safe.”

Sorry...

How does one determine an average in an open system?

It is not difficult, let us say that you want to make an average of dam capacity. Today you go measure the depth, mark the spot you used and then next year on the exact same day and approximately the same hour you go measure it again. Records for California has been dutiful recorded from the early 1800s so they have prior data to compare.

Thats great however California has a long way to go before its groundwater is replenished.

Brown was an idiot (to be nice) to cut spending based on climate projections.

Would this not require one to prepare for the extremes on both sides of the system?
Or even past prior extremes...

200 years is most impressive...
They should be prepared...

The city I live in flooded in the 90's... Hard for me to believe because the river is contained by banks that are forty feet higher than the average...

It's one of the big fears...
Other than that and an occasional ice storm we are pretty secure up here...

Yep...
That doesn't make much sense...

You can use a running mean (moving average) and any variance against it then could be measured to tell you where you were in any given year.

For example, suppose we have a twelve-month average of 16 and the thirteenth month come in at 32. We would have a 100% increase over average in an open system...

If you were smart you would. The whole premise behind Climate Change is changing weather patterns but that doesn't mean that we won't have years that are hotter than normal and years that are colder than normal only that the running mean is getting progressively hotter overall. In states prone to drought they should be making plans for containing water during periods of heavy rainfall and snowfall. This would mean creating new lakes, deepening existing lakes, and maybe even storing it in underground aquifers.

With groundwater being depleted faster than it can be replenished you’d think they would invest more in storage and technology to convert saltwater to fresh. The technology already exists and is used on ships and by Saudi Arabia.

Seems your comment~~”This would mean creating new lakes, deepening existing lakes, and maybe even storing it in underground aquifers.” is a very good suggestion.. You would think Cali would consider such or should have by now anyway...Both seem viable and well worth the investment..

But lindajoy that cost money something the California government likes to collect but not spend because their broke and way over their heads in debt I hear and thinking ahead well they don't do that well from where I set their chasing more business away then pulling them in

Aw heck bg, carrying 400 billion in bond debt means nothing to them.. Why not add a bit for a truly good cause??
