大沼泽蓄水库地基与截水墙完成一半：17,000英亩工程2029年完工、比原计划提前五年
美国陆军工程兵团杰克逊维尔分局宣布，位于佛罗里达州 Lake Okeechobee 以南大沼泽农业区的 EAA 蓄水库，其地基与截水墙工程已经完成一半，这座为修复大沼泽而建的大型蓄水库正朝着2029年完工、比原计划提前五年的目标推进。
主管陆军土木工程的高级官员 Lee Forsgren 公布了这一节点。负责地基与截水墙的 11A 号合同已完成全长15.84英里线路中的约8英里，施工进度比计划快34天，合同工期累计压缩了15个月，定于2028年3月完成。
EAA 蓄水库占地17,000英亩、约26.5平方英里，面积大于 Manhattan，可蓄水超过780亿加仑。工程连同配套水处理设施，预期每年可向大沼泽和 Florida Bay 输送多达4,700亿加仑的净水，把 Lake Okeechobee 的水引向大沼泽中南部，减少向南佛罗里达河口的有害泄流。
整个水库由兵团三份合同分段建设：进出水与防渗渠道的 10A 号合同已经完工，11A 号合同负责地基与截水墙，负责堤坝和水控建筑物的 11B 号合同要求2029年12月完工。工程土方开挖量达3,320万立方码，相当于725,000车次自卸卡车，坝体接近七层楼高。
提速来自2025年陆军与佛罗里达州达成的协议：兵团专注于水库地基、堤坝、周边渠道和建筑物，南佛罗里达水管理局负责防渗与进水泵站及 Blue Shanty Flow Way。Forsgren 说，这座水库将让净水在需要的时间送往需要的地方，保护南佛罗里达的饮用水并支撑当地经济。（来源：美国陆军工程兵团）
Everglades Reservoir Foundation and Cutoff Wall Reach Halfway Point, With Completion Due in 2029, Five Years Early
The U.S. Army Corps of Engineers' Jacksonville District announced that construction of the foundation and cutoff wall for the Everglades Agricultural Area (EAA) Reservoir, south of Lake Okeechobee in Florida, is 50 percent complete, keeping the Everglades restoration project on track for completion in 2029, five years ahead of the original schedule.
Lee Forsgren, Senior Official Performing the Duties of the Assistant Secretary of the Army for Civil Works, announced the milestone. Under Contract 11A, about eight miles of the reservoir's 15.84-mile foundation and cutoff wall alignment are complete, construction is 34 days ahead of schedule, and the contract timeline has been accelerated by 15 months, with completion set for March 2028.
The reservoir covers 17,000 acres, about 26.5 square miles, larger than Manhattan by land mass, and is designed to store more than 78 billion gallons of water. Together with associated treatment infrastructure, it is expected to deliver up to 470 billion gallons of clean water annually to the Everglades and Florida Bay, moving water from Lake Okeechobee south and reducing harmful discharges to South Florida's estuaries.
The reservoir is being built under three Corps contracts: Contract 10A, covering inflow, outflow and seepage canals, is complete; Contract 11A covers the foundation and cutoff wall; and Contract 11B, covering the embankment and water control structures, has a required completion date of December 2029. Excavation totals 33.2 million cubic yards, about 725,000 dump truck loads, and the structure stands nearly seven stories tall.
The acceleration follows a 2025 agreement between the U.S. Army and Florida under which the Corps focuses on the foundation, embankments, perimeter canals and structures while the South Florida Water Management District builds seepage and inflow pump stations and takes responsibility for the Blue Shanty Flow Way. "This reservoir will allow us to send clean water south when and where it's needed, protect South Florida's drinking water, and support its economy," Forsgren said.
