How They Voted, March 5

The Carlsbad City Council met Tuesday for a public hearing and approved permits for a proposed four-story mixed-use building, including retail and office uses, and 106 apartments, 16 of which will be affordable housing, on Carlsbad Village Drive. The council also heard a report on public safety in the north beach area, and directed staff to bring back information before summer, including on outreach, lifeguard towers and gate closures. A discussion of permits for a condominium project at Poinsettia Lane was moved to the March 14 meeting.

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.

Hydropower Poised For Comeback in California, Thanks To A Wet Winter

California’s years-long drought put hydroelectric power flat on its back. But one of the cleanest and cheapest energy sources may be poised for a comeback as the state has been drenched with rain and its mountains blanketed in snow in recent months. Energy officials studying the numbers are cautiously optimistic the sector’s output may roar back to levels seen before drought decimated watersheds, streams and reservoirs.

 

Rain Brings Water and Relief to Area

The ferocious winter storm that flooded roadways and knocked down old Eucalyptus trees in South County has helped with water conservation measures. The San Diego County Water Authority in the past few months has officially declared an end to the  five-year long water drought. While the drought appears to be over, the California Water Resources Control board still believes water agencies and users need to conserve water. The drought is no more because of conservation methods by local water agencies and because of the abundance of rain this winter.

Winter Storms Cause Massive Sewage Spills In Sacramento Region

Just as recent storms revealed weaknesses in Northern California’s dams and levees, they also exposed problems with Sacramento-area wastewater systems that failed to contain sewage. Record precipitation in the last two months created more pressure than some sewer lines and plants could handle. From Jan. 1 to March 2, more than 1 million gallons of wastewater spilled in the capital region, most into waterways, according to reports made by sewage districts to the State Water Resources Control Board. While spills occurred in several communities, most were in areas served by the Sacramento Area Sewer District and the city of Placerville.

Oroville Dam Power Plant Back Online

The Hyatt Powerhouse under Oroville Dam went back online Friday after removal of debris from the bottom of the main Oroville Dam spillway allowed the level of the Diversion Pool to be reduced. Acting Department of Water Resources Director Bill Croyle said in a press conference at noon Friday that two of the six turbines were in operation and that the power plant would be ramped up as the day went along. Croyle said one of the six turbines is under maintenance.
