Allatoona Project Releases High Water, Carters Lake Receding
MOBILE, Ala. – The U.S. Army Corps of Engineers Mobile District at Allatoona Lake Project has begun releasing water through its dam spillway as of 3:00 p.m. EST on Feb. 21, 2020 due to high water levels at the reservoir. In addition, USACE Mobile District’s water management efforts – along with reduced inflows from lighter rainfall – have helped the main reservoir's high water level recede at Carters Lake Project.

The Jan. 7 Los Angeles County wildfires debris removal operation was one of our largest, most challenging missions. More than 1,400 USACE personnel deployed from across the nation and from our district to support debris removal operations. /6

But we did not do this alone. The success of this important mission was the result of strong partnerships with FEMA, Cal OES, LA County, local governments and impacted communities. /5

To date, USACE has removed more than 2.6 million tons of debris — the equivalent of more than 218,000 truckloads. /4

We are proud of our efforts, alongside our partners, to rapidly come to the aid of our fellow citizens in their time of need. In just six months, more than 9,500 properties were cleared — making this the fastest, large-scale wildfire debris removal in USACE history. /3

After the devastating Los Angeles wildfires in January 2025, the U.S. Army Corps of Engineers was laser-focused on removing immediate hazards to public health and safety, and supporting economic recovery by removing structural ash, debris and foundations. /2

This week marks one year since the January 2025 Southern California wildfires began. On Jan. 17, the U.S. Army Corps of Engineers began its debris removal mission, which was a critical step in the road to recovery. https://t.co/iF1yZ5D6CP

PUBLICATION NOTICE: Improved Vehicle Mobility by Using Terrain Surfacing Systems
Abstract: Even for military vehicles designed with superior off-road capabilities, problematic soil conditions can impede mobility, particularly when many vehicles need to traverse the same path. Loose sands with little shear strength or wet silts or clays with little bearing capacity can deform rapidly under traffic. U.S. Army Engineer Research and Development Center researchers conducted field testing over several terrain conditions to measure performance of terrain surfacing systems designed to improve vehicle mobility. Soil conditions included poorly-graded sand, medium-strength silt, weak marsh, and two different slope conditions. Five different terrain surfacing, or matting systems, were tested that included four commercial variants and one U.S. government design. All testing took place at the ERDC Ground Vehicle Terrain Surfacing Test Facility in Vicksburg, Mississippi. Military test vehicles included a Marine Tactical Vehicle Replacement, Common Bridge Transporter, and M1 Abrams tank. Results from the testing showed that all matting systems provided notable improvement in the number of allowable vehicle passes over soft sands. Results varied for the different systems over weaker soils, with performance improved for those matting systems having thicker and stiffer panels. However, improved performance among matting systems came with a sacrifice of increased logistical burden. Data presented here-in include detailed site characteristics and soil deformation as a function of traffic.

PUBLICATION NOTICE: Laboratory Characterization of Rapid-Setting Flowable Fill
Abstract: Utility Fill One-Step 750® is a rapid-setting flowable fill product that has previously been validated in numerous full-scale demonstrations as an expedient backfill solution for Rapid Airfield Damage Recovery. Although the field performance of Utility Fill One-Step 750® has been extensively documented, a full laboratory characterization has not been conducted. This report analyzes and documents results from several laboratory tests conducted at two water to-product ratios. The tests conducted are based on the suite of tests that make up the triservice spall repair certification program used for rapid-setting concrete products. Tests include strength and set time-related properties, typical parameter control tests for concrete, and tests to determine the mineralogy and chemical makeup of the material. Long-term expansion and contraction properties were also tested. The data presented herein are intended to provide an overall assessment of Utility Fill One-Step 750® and to provide reasonable estimates of various design parameters. The results can be used as a basis for the future development of a formal laboratory certification protocol to down-select other rapid-setting flowable fill products for further evaluation.

PUBLICATION NOTICE: Lake Providence to Old River Geomorphology Assessment
Abstract: This report integrates information from previous geomorphic studies coupled with new analysis to provide a comprehensive geomorphic characterization of the Lake Providence (River Mile [RM] 487.2 Above Head of Passes [AHP]) to Old River Control Complex, (RM 317 AHP) reach from the early-1800s to present. Individual components of this study included the following: historical geomorphic studies, development of an events timeline, specific gage records, stage and flow duration trends, trends in water surface slopes, bed material studies, suspended sediment data, channel geometry data, and effects of channel improvement features (cutoffs, dike, revetment, and dredging). These individual assessments were consolidated to develop an overall assessment of how the study reach has evolved since the early-1800s.
