19.5亿美元圣华金河下游防洪工程关键堤段完工：斯托克顿市Tenmile Slough堤防赶在厄尔尼诺冬季前达标，将护12.2万居民
加州水资源厅（DWR）10月30日宣布，位于加州圣华金县斯托克顿市的 Tenmile Slough 堤防关键堤段已经完工，赶在厄尔尼诺（El Niño）可能带来的多雨冬季到来之前达标。该厅当日与美国陆军工兵团、中央谷防洪委员会及圣华金地区防洪局的官员共同纪念这一节点。
Tenmile Slough 堤段是圣华金河下游防洪工程的重要组成部分。该工程总投资19.5亿美元，由加州水资源厅、美国陆军工兵团与圣华金地区防洪局共同出资；全部完工后，将为斯托克顿市北部与中部沿圣华金河一带的12.2万名居民及287亿美元财产提供更高等级的防洪保护。
水资源厅防洪与大坝安全副厅长劳拉·霍伦德（Laura Hollender）表示：「过去十年，中央谷防洪系统的重大投入持续降低了我们社区的洪水风险。这段最新完工的堤防证明这些投入正在见效。随着厄尔尼诺预计今冬影响加州，州政府正确保我们的防洪系统在第一场风暴到来之前就绪。」
据水资源厅介绍，这段 Tenmile Slough 堤防此前被评为中央谷堤防系统中缺陷最严重的堤段。1997年历史性洪灾之后，该厅与中央谷防洪委员会确认圣华金河流域存在重大洪水风险，联邦、州与地方伙伴随即合作评估并设计所需的改进工程。斯托克顿市此前的其他关键防洪项目还包括投资9,400万美元的 Smith Canal 闸门结构，可为该市中部2.4万户家庭提供防洪保护。

$1.95 Billion Lower San Joaquin River Project Marks Milestone as Critical Tenmile Slough Levee Segment Is Completed in Stockton Before El Niño Winter
The California Department of Water Resources (DWR) announced on October 30 that a critical segment of the Tenmile Slough levee in Stockton, in San Joaquin County, California, has been completed in time for an El Niño winter. DWR joined officials from the U.S. Army Corps of Engineers, the Central Valley Flood Protection Board, and the San Joaquin Area Flood Control Agency to mark the completion of the levee segment and a major milestone in reducing flood risk for the City of Stockton.
The Tenmile Slough levee is a critical component of the larger Lower San Joaquin River Project, a $1.95 billion project funded by the California Department of Water Resources, the U.S. Army Corps of Engineers, and the San Joaquin Area Flood Control Agency. Once completed, the project will provide improved flood protection for 122,000 residents and $28.7 billion in property along the San Joaquin River for the North and Central Stockton area.
"Over the past decade, significant investments across the Central Valley Flood System have driven down flood risk for our communities. This newest completed levee segment demonstrates how those investments are paying off," said Laura Hollender, DWR deputy director of flood management and dam safety. "With El Niño anticipated to impact California this winter, the State is making sure our flood system is ready before the first storm arrives."
Before the completion of this project, the Tenmile Slough levee segment was rated as the most critically deficient in the Central Valley levee system. Following historic flooding in 1997, DWR and the Central Valley Flood Protection Board identified significant flood risk in the San Joaquin River Basin, and federal, state, and local partners worked together to evaluate and design the improvements. Other completed flood projects for Stockton include the Smith Canal Gate Structure, a $94 million project providing flood protection for 24,000 homes in central Stockton, DWR said.
