  • Corps of Engineers celebrates National Safe Boating Week

    The U.S. Army Corps of Engineers, St. Paul District, is celebrating National Safe Boating Week by reminding boaters on the Mississippi River to be smart while on the water.

  • Development and Testing of the FRAME Tool on a 200-Mile Reach of the Lower Mississippi River

    Abstract: Understanding the likely long-term evolution of the Lower Mississippi River (LMR) is a challenging mission for the US Army Corps of Engineers (USACE) that remains difficult for conventional river engineering models. A new type of model is currently in development, tasked with revealing uncertainty-bounded trends in sediment transport and channel morphology over annual, decadal, and centennial timescales. The Future River Analysis and Management Evaluation (FRAME) tool is being designed with river managers and planners in mind to provide exploratory insights into plausible river futures and their potential impacts. A unique attribute of the tool is its hybrid interfacing of traditional one-dimensional hydraulic and sediment transport modeling with geomorphic rules for characterizing the morphological response. This report documents the development of a FRAME test-bed model for a 200-mile reach of the Mississippi River upstream of Vicksburg, Mississippi. This testbed allowed development and testing of the prototype FRAME tool in a data-rich environment. This work identified proposed future developments to provide river managers and planners with a fully functional tool for delivering insights on long-term morphological response in river channels across a variety of spatial and temporal scales.

  • Mississippi River Visitor Center Operating Days Change

    Starting May 20, the Mississippi River Visitor Center operated by the U.S. Army Corps of Engineers, Rock Island District, at Locks and Dam 15 on the Rock Island Arsenal will be open to the public from 9 a.m. to 4 p.m., Tuesday-Friday each week.

  • Corps to Host Sabula Lakes Project Open House, May 20

    The U.S. Army Corps of Engineers, Rock Island District, is hosting an open house May 20 to provide an update on the ecosystem restoration project planned for the Sabula Lakes area of the Mississippi River. The event will take place from 5:30-7:30 p.m. at the Izaak Walton League located at 60190 US-52 in Sabula, Iowa.

  • Corps to host public informational meeting in Prairie du Chien, Wis., May 13

    The U.S. Army Corps of Engineers, St. Paul District, will host an informational meeting to introduce the public to its ongoing work in the areas of Pools 8 through 10 of the Upper Mississippi Area, May 13, from 4-5:30 p.m. A presentation will begin at 4:30 p.m.

  • Review of Mississippi River Sediment-Sampling Protocols

    Abstract: The Mississippi River sediment data protocols located in the US Army Corps of Engineer (USACE), St Louis, Memphis, Vicksburg, and New Orleans Districts, were reviewed and evaluated. The review included both USACE and US Geological Survey (USGS) sampling sites. The purpose of this review was to evaluate the reported historical sediment data and to provide guidance for moving forward with an accurate and consistent sediment data collection program. The review was focused on the reliability of the reported historical data and its usefulness for use in sedimentation studies related to long-term aggradation, degradation, and dredging. Recommendations to implement effective sediment data collection, laboratory analyses, and reporting were provided.

  • Corps of Engineers hosts Lower Pool 10 restoration project groundbreaking

    ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is celebrating the start of the Lower Pool 10 habitat rehabilitation and enhancement project with a groundbreaking ceremony April 22, at 1 p.m. at the North Gazebo in Guttenberg, Iowa.

  • First tow of 2025 season reaches Mississippi River head of navigation

    The U.S. Army Corps of Engineers, St. Paul District, announced today, March 20, that the first tow of the 2025 navigation season arrived in St. Paul, Minnesota.

  • Old River Control Low Sill Structure: Monitoring and Performance

    Abstract: The Old River Low Sill Structure (ORLSS) is located approximately 25 mi south of Vidalia, LA, and is part of the Old River Control Complex. The structure is founded on steel piles and is a 566-foot-long concrete structure constructed in 1959. The structure resembles a dam with 11, 44-foot-wide gates to prevent migration of the Mississippi River’s current course to a hydraulically shorter course down the Atchafalaya River. A re-analysis was undertaken by the US Army Engineer Research and Development Center to investigate the current level of stability and the potential for adjusting the operating limitations placed on the structure because of damage during the 1973 flood. The investigation was performed by reviewing the design and post-design stability analyses, analyzing performance data, and performing an updated stability analysis. The stability analysis was performed with monitoring data that spanned several decades. Using historic monitoring data in the stability analysis, with a wide range of loading conditions, it was shown that uplift conditions were not as severe as previously considered. Performance data coupled with the stability analysis show that the structural performance supports the current operating conditions.

  • FREE boating safety courses to be offered at Mississippi River Project Office

    The U.S. Army Corps of Engineers, Rock Island District, is offering free boating safety education classes at the Mississippi River Project Office near Locks and Dam 14 in Pleasant Valley, Iowa. These courses are designed to equip boaters of all experience levels with essential safety knowledge before heading out on the water. Classes will be offered April 5, 12, 19, and 26, from 8 a.m. to 4:30 p.m. and are open to anyone 11 or older. While no on-the-water training is provided, the classroom-based instruction covers key boating safety principles. Boaters 12 and older who successfully complete the course and pass the final exam will receive an Illinois Department of Natural Resources Boat Safety Certification, which is recognized in both Illinois and Iowa.
