Jerry Brown Requests A Third Presidential Disaster Declaration

Gov. Jerry Brown asked President Donald Trump on Tuesday to declare a major disaster for California due to damage caused by heavy rains that hit the state from Jan. 18 to 23. “This record-breaking precipitation resulted in numerous rivers, creeks and streams again exceeding flood stages throughout California,” Brown wrote Trump, saying the storms caused flooding, breached levees, left an estimated 55,000 homes and businesses without power, and led to six deaths. A presidential disaster declaration would make available federal assistance to reimburse state and local costs, small-business loans and other programs.

Drought Monitor Shows Dramatic Changes To National Map

The latest Drought Monitor map was made public to begin March and shows a significant improvement in the very dry conditions experienced for months in the west, but a very different story for portions of the southern plains, the southeast and the northeast US.

Water Flowing Through Oroville Dam Powerhouse Again

Water was running again through the Hyatt Powerhouse beneath Oroville Dam on Monday evening. Water was sent through the hydroelectric power plant Friday for the first time since Feb. 10, but the flow was shut off about 10 a.m. Saturday when Department of Water Resources officials realized they needed a bigger channel through the debris at the base of the damaged main spillway for the powerhouse to operate at full capacity.

Oroville Dam: Farmers Blame Sudden Spillway Shutoff For Eroded Riverbanks

For three generations, Phillip Filter’s family has tended orchards that grow on a shelf of floodplain above the Feather River. Because the trees stand between the river and a major flood-protection levee, Filter’s family is no stranger to floods that sometimes spill over the river banks, inundate the orchards and then recede back into the channel below. But Filter has never seen damage to the riverbanks like what happened last week after the state suddenly shut down flows from Oroville Dam’s badly damaged spillway upstream.

Money, Politics And The Twin Tunnels

In the wake of the Oroville dam near-disaster, a question floating around Capitol corridors now is:  Given the amount of money needed for what everyone agrees must be an expensive revamping of the state’s water infrastructure, is there room now for Gov. Jerry Brown’s heart’s desire — the $15.5 billion twin tunnels project? “This project has been subjected to 10 years of detailed analysis and more environmental review than any other project in the history of the world. It is absolutely essential if California is to maintain a reliable water supply,” Brown declared in a formal statement issued on Dec. 22, 2016.

OPINION: Ignored Oroville Warning Raises Big Questions

Just because nature allows a delay of many years while officials dither over a catastrophe in the making doesn’t make that disaster any easier to handle when it finally strikes. This is one major lesson of the Oroville Dam spillway crisis that saw the sudden evacuation of almost 200,000 persons from their homes when the dam’s emergency spillway crumbled under the force of millions of gallons of fast-moving water. Warnings of precisely this sort of crisis at Lake Oroville were submitted to the Federal Energy Regulation Commission during a 2005 relicensing process, almost 12 years before those predictions came true.

 

California’s Reservoirs Are Filled With Gunk, And It’s Crowding Out Room To Store Water

Let’s say you owned a four-bedroom house, but one room was useless because of clutter. You’d probably eventually take a deep breath and clear out the crap. You’d reclaim the room. That’s pretty much the situation with many reservoirs in California. They’ve got too much gunk in them. And it’s crowding out space for water storage. But you don’t hear any deep breaths being taken in Sacramento. There’s no serious thought of removing the junk — silt, sand, gravel — and making more room for storm runoff.

Rains Expose a New Water Problem in California: Storage

Since the beginning of the year, enough water has spilled out of California’s rain-swollen Lake Oroville to meet the demands of roughly 14 million people for a year. With no place to store the excess, much of it ended up flowing out to sea. It wasn’t just last month’s dramatic near-disaster at Lake Oroville’s dam that is to blame for the water loss. After years of drought, months of rains are exposing a major weakness in California’s water system: lack of storage.

 

Bill Would Speed Up Review of Proposed Reservoir

Citing recent events at Oroville Dam, two congressmen have introduced a bill to speed up approval of a new reservoir in Northern California. The bill, HR1269, would accelerate federal review of the proposed Sites Reservoir and give officials a better chance at funding for the project under Proposition 1 bond funding, according to a news release from U.S. Rep. Doug LaMalfa, R-Richvale.

West’s Super Floods May Wash Over Aging Dams, Scientists Warn

In the late 1980s, a Japanese scientist named Koji Minoura stumbled on a medieval poem that described a tsunami so large it had swept away a castle and killed 1,000 people. Intrigued, Minoura and his team began looking for paleontological evidence of the tsunami beneath rice paddies, and discovered not one but three massive, earthquake-triggered waves that had wracked the Sendai coast over the past 3,000 years. In a 2001 paper, Minoura concluded that the possibility of another tsunami was significant.
