Parenting during COVID-19
In the United States Military, 44.1% of active duty members have children. Suddenly many of us were told to stay home unless we leave for essential reasons. This means a lot of us are now trying to complete the mission with kids at home as their schools and daycares have been canceled.

Sandy Lake Dam Rehabilitation Project, Aitkin County, Minnesota
Over its history, Sandy Lake Dam has undergone a series of modifications, repairs and periodic inspections. From 2011 to 2016, a series of above and below water inspections identified several features that had deteriorated to a point that repair or replacement were necessary to maintain the long-term stability of the structure. Sandy Lake Dam is located on the Sandy River in Aitkin County, Minnesota, 1.25 miles upstream of the junction between the Sandy River and Mississippi River.

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: Laboratory spiking process of soil with various uranium and other heavy metals
Abstract: Laboratory studies using metal spiked soils are challenging due to soil heterogeneity. This work provides an easy, quick, precise, and accurate technique for the preparation of spiked soils for laboratory research. The process described spiking soil with various uranium species and other heavy metals for laboratory scale pilot experiments under various biogeochemical conditions. The procedure involves grinding both dry soil and metal chemicals into the fine powder. The spiked soil mixture was further homogenized through a modified splitting and combining of the sample by diagonal flipping using plastic sheeting. Comparison of measured concentrations with theoretical values were obtained with <20% precision and accuracy. However, tradition spiking method with metal solution of-ten yielded high heterogeneous spiked soils due to strong metal adsorption in soils. Re-drying and re-grinding of soils were required following the spiking in order to homogenize treated soils, generating inhalable particulates. Thus appropriate personal protective equipment and practices are required for the safety concern. The present method with metal salt powder proved a safe, useful, quick, accurate and precise, and homogenized soil spiking method.

PUBLICATION NOTICE: Spatial Analysis of Precipitation and Snow Water Equivalent Extremes for the Columbia River Basin
Abstract: Recent advances in the spatial statistics of extremes and model calibration were applied to develop and deliver areal-exceedance estimates for precipitation (PREC), by season and duration, and snow water equivalent (SWE), by cool season month and for the water year, for 758 delineated sub-basins of the Columbia River Basin (CRB), which correspond to a new CRB hydrology model watershed delineation. Understanding that future US Army Corps of Engineers, Northwestern Division, mission requirements may change, project execution also included the development and delivery of an application guidance document to credibly compute areal-exceedance estimates, including uncertainty, for PREC or SWE for any arbitrary area within the CRB. R, a free software environment for statistical computing and graphics (https://www.r-project.org/), and QGIS, a free and open source geographic information system (https://qgis.org/en/site/index.html), were the primary tools used for product development and delivery. The following R software packages were primarily used during project execution: evd, Glmnet, maps, raster, rgdal, SDMTools, sp, and SpatialExtremes.

Corps announces public comment and webinar on planned deviation from Lake O Regulation Schedule to reduce risk from Harmful Algal Blooms
The U.S. Army Corps of Engineers Jacksonville District, announces public comment on the Draft Revised Supplemental Environmental Assessment (EA) and Proposed Finding of No Significant Impact (FONSI) for the planned deviation from the water control plan for Lake Okeechobee and the Everglades Agricultural Area, also known as the Lake Okeechobee Regulation Schedule (LORS 2008) in order to reduce risk from Harmful Algal Blooms. A webinar to provide information regarding the proposed planned deviation is planned for 1 p.m. on July 21. Public comments are due July 30.
