LaMalfa Urges President Trump To Help Facilitate Oroville Dam Spillway Repair

Congressman Doug LaMalfa (R-Richvale) issued the following statement after sending a letter, along with many of his colleagues in the California congressional delegation, urging President Trump to take immediate action to facilitate the work required to repair the two Oroville Dam spillways that were damaged in the February 2017 storm events. The damage forced the mandatory evacuation of nearly 200,000 residents, and President Trump responded by declaring a Major Emergency and authorizing the Federal Emergency Management Agency to assist local and state officials and provide aid to evacuees.

Just Weeks After Oroville Dam Crisis, Damage Found In Another Key California Reservoir

California water officials, still struggling with fixes at Oroville Dam, will have to temporarily shut down the pumping station that delivers water to much of Southern California and Silicon Valley after discovering damage at another key state reservoir. The state Department of Water Resources confirmed Tuesday that operators discovered damage to the intake structure at the Clifton Court Forebay, a nearly two-mile-wide reservoir that stores water for the State Water Project pumping plant in the Sacramento-San Joaquin Delta near Tracy. Repairs will begin Wednesday. It’s not clear how long they will last.

BLOG: The Dangers Of Land Subsidence From California’s Groundwater Overdraft

Land subsidence from overpumping groundwater in the San Joaquin Valley has been called the largest human alteration of the Earth’s surface. When the last comprehensive surveys were made in 1970, subsidence in excess of one foot had occurred over more than 5,200 square miles (13,000 sq km) of irrigable land – half the entire valley. Southwest of Mendota, a town that prides itself on being the cantaloupe center of the world, maximum subsidence was estimated at 28 feet (8.5m). By this time, however, massive infusions of surface water were being delivered to the valley, and subsidence was slowing or had been “arrested.”

Santa Barbara County Moves Up A Notch In Drought Designation

After five years of increasing drought, the level of Santa Barbara County’s thirst on Monday finally climbed from “severe drought” to “moderate drought,” according to the U.S. Drought Monitor, which began keeping track of the statewide situation in December 2011. Santa Barbara County didn’t fall into drought until the eighth week of 2012 when it hit the monitor’s chart at “abnormally dry” before climbing through two additional levels until about September 2013, when along with San Luis Obispo and parts of Kern counties it became the first area in the state to reach “extreme drought.”

California Farmers Give Mixed Reactions To Recent Rainfall

After record winter rainfall helped alleviate California’s drought, the relentless storms have left some farmers frustrated with the rain’s negative effects on their profit margins. Immanuel Solis, a longtime flower cultivator and merchant from Watsonville, noted that business at the local farmer’s markets has been slow. “[Customers] do not want to bring plants to their homes or gardens because of the rain” he said.

 

Climate Change Complicates The Whole Dam Debate

With California now on track to have the rainiest year in its history—on the heels of its worst drought in 500 years—the state has become a daily reminder that extreme weather events are on the rise. And the recent near-collapse of the spillway at California’s massive Oroville Dam put an exclamation point on the potentially catastrophic risks. More than 4,000 dams in the U.S. are now rated unsafe because of structural or other deficiencies. Bringing the entire system of 90,000 dams up to current standards would cost about $79 billion, according to the Association of State Dam Safety Officials.

Massive Tijuana Sewage Spill That Polluted San Diego Beaches Part Of Larger Problem

Baja California’s governor is preparing to declare a state of emergency in the coming days, hoping to draw financial aid for Tijuana’s strained and underfunded sewage system following a massive spill that sent millions of gallons of untreated wastewater from Tijuana across the border and into San Diego last month.

Scientists Map Seawater Threat To California Central Coast Aquifers

Researchers from Stanford and the University of Calgary have transformed pulses of electrical current sent 1,000 feet underground into a picture of where seawater has infiltrated freshwater aquifers along the Monterey Bay coastline. The findings, which will be published in an upcoming issue of the Journal of Hydrology but are available online now, help explain factors controlling this phenomenon, called saltwater intrusion, and could help improve the groundwater models that local water managers use to make decisions about pumping groundwater to meet drinking or farming needs.

OPINION: Taxpayers Deserve Transparency On Oroville Expenses

It is a simple question really: How much is the massive repair project below Lake Oroville costing each day. Simple or not, it has been appallingly difficult to get it answered. Representatives of our newspaper group have been asking how much the crisis at the dam is costing and, oh yes, who’s picking up the tab? The reporters have asked how many state employees are working, how many contractors are employed and what it costs for all the equipment.

Is There Too Much Water Behind Oroville Dam? Critics Say Army Corps Standards Unsafe

Long before a fractured spillway plunged Oroville Dam into the gravest crisis in its 48-year history, officials at a handful of downstream government agencies devised a plan they believed would make the dam safer: Store less water there. Sutter County, Yuba City and a regional levee-maintenance agency brought their recommendation to the Federal Energy Regulatory Commission in 2006, when FERC was considering the state’s application to relicense Oroville Dam.
