The long debate over Poseidon Water’s proposed ocean desalination plant in Huntington Beach continued this week as the California State Lands Commission released a draft of a supplemental environmental impact report analyzing planned additions to the facility that are meant to reduce potential harm to marine life and increase the plant’s efficiency. The supplement to a 2010 EIR addresses the possible environmental effects of a screen and diffuser added to the intake and outflow pipes, respectively, that would be used by the $1-billion desalination facility proposed at Newland Street and Pacific Coast Highway.
In the wake of the recent drought, desalination of ocean water continues to be a central topic in California water debates. Some coastal communities were particularly hard hit by the drought, including a large swath of the central coast that is among the last regions in the state still suffering from drought conditions. Desalination seems to hold the potential for limitless, drought-proof supplies, but the reality is far more complex.
California’s historic winter ended the drought in many parts of the state and piled up record levels of snowpack in the Sierra Nevada Mountains. With so much precipitation, surface water infrastructure – our network of dams, reservoirs and levees – has been called into action like never before, and in some cases has struggled to handle the influx of flows.
If you’re expecting a quick and easy answer on what caused the spillway failure at Oroville Dam, think again. The leader of the independent forensics team studying the Oroville crisis said Thursday that the crack in the dam’s main flood-control spillway likely was caused by a combination of problems. “We do anticipate there will be multiple contributory factors, no single factor,” said dam safety consultant John France in a conference call with reporters.
Officials say they have installed a new emergency siren at a Northern California dam whose damaged spillway forced evacuations earlier this year. The state Department of Water Resources says it will conduct the first test of the new siren at Oroville Dam on Friday. Monthly tests in July and August will follow. The previous siren was lost during water releases in February. Construction crews have begun demolishing the destroyed portion of the main spillway at the dam, which is the nation’s tallest.
