With Harvey and Irma understandably making headlines, it can be easy to be forget the infrastructural crises we’ve already had to deal with this year. Take the overflow of the Oroville Dam spillway in northern California back in February. The California Department of Water Resources (DWR) has released a flyover of the spillway in its current form, in the midst of reconstruction.
Dam removal is a relatively new area of science. It wasn’t until the mid-1990s that tearing down a dam to restore a river became a regular occurrence across the United States. Most dam removals have been studied and monitored closely to ensure that results meet expectations and to avoid harmful consequences. But there haven’t been many comprehensive reviews of the field of dam removal to answer broader questions, such as: How many dam removals actually helped fish recolonize rivers? How long did that take? What were the effects of releasing sediment stored behind dams?
As state lawmakers debate far-reaching bills that could reshape the energy landscape in California and across the West, some groups are urging the Legislature to require new geothermal power plants at the Salton Sea before a key deadline Tuesday* night — but those groups can’t agree on what the geothermal mandate should look like.
In the coming weeks, water agencies throughout California will make important decisions about a project that modernizes our state’s water system. About a third of the water used in Southern California comes from Northern California through the State Water Project. But the hub of that water delivery system, the section carrying water to the Southland from the state’s two largest rivers—the Sacramento and San Joaquin—through a region known as the Delta, needs to be modernized.
After suffering more than a week under searing, desert-like heat, winter might be the furthest thing from the minds of most Californians. However, to borrow a phrase from TV’s “Game of Thrones,” winter is coming. The only question is whether the gods will allow a rerun of last winter which unexpectedly dumped record amounts of rain and snow throughout the state that filled reservoirs and kept skiers on the slopes through August.
A “sanctuary state” bill deal, the emergence of a $4 billion parks and water bond, two new California legal fronts against the Trump administration, and the Mexican foreign minister’s visit to the state Capitol – just another Manic Monday as lawmakers begin their final week of work before adjourning for the year.
Last week, my colleague published a report entitled Mismatched: A Comparison of Future Water Supply and Demand for the Metropolitan Water District of Southern California and Its Member Agencies. The report compares the 2015 Urban Water Management Plans prepared by the Metropolitan Water District of Southern California (MWD) and its member agencies. It documents that in average water years, MWD’s plan assumes that demand for imported water is hundreds of thousands of acre feet higher than the local agencies’ plans.
Gov. Jerry Brown is trying to force California water agencies, including the Santa Clara Valley Water District, to vote in the next month on whether they will pay for building his $17 billion “WaterFix” Delta tunnels project. It is an arbitrary, outrageous and irresponsible deadline. There is no formal agreement on how the project will be financed, how it will be governed or how the water will be allocated: none of the information a responsible water board needs to know for an informed decision.
On Aug. 28, the Central Basin Water Board voted, 5-2, to postpone a decision on California Gov. Jerry Brown’s proposed Delta Tunnel project (also known as California Water Fix) until rate impacts of the project can be clarified. Specifically, officials are concerned about the burden citizens from poorer areas of Los Angeles County will bear without seeing an increase of water supplies. The $25 billion California Water Fix proposes to construct several massive underground tunnels that will update California’s water infrastructure by diverting more water, making the delivery more reliable and improving environmental conditions.
In the confusion and chaos of the emergency at Oroville Dam, as thousands of residents were being evacuated, public safety officials and others involved in managing the crisis found themselves clashing with the people operating the nation’s tallest dam. Butte County Sheriff Kory Honea questioned an assertion by the director of the state Department of Water Resources that the situation was stabilizing.
