  • Heavyweight precision: Medium capacity fleet tackles 235,000-pound miter gates repairs

    The U.S. Army Corps of Engineers Medium Capacity Fleet removed the miter gates from the main chamber to perform repairs at New Cumberland Locks and Dam on the Ohio River in Stratton, Ohio, April 15, 2025.

  • Ohio River flooding disrupts locking operations at Markland and McAlpine

    Locking operations at Markland Locks and Dam (Ohio River Mile 531.5) have been suspended due to high water. At McAlpine Locks and Dam (Ohio River Mile 606.8), the south (landside) chamber has ceased operations, and the north chamber is expected to close by the evening of Sunday, April 6, 2025. Additional impacts are expected downstream as river levels rise. A full summary of projected impacts at the district’s seven locks and dams on the Ohio River are listed below.

  • Greenup Auxiliary Lock Closure Limits Recreational Lockages

  • Montgomery Locks and Dam, Ohio River: Navigation Approach Physical Model

    Abstract: A physical model study of the Montgomery Locks and Dam was conducted to optimize the navigation conditions for the new riverside lock and guard wall design developed by the Pittsburgh District. A 1:100 Froude scale physical model was built to evaluate the navigation conditions for tows entering and exiting the locks in the upstream and downstream approaches. Conditions tested were Existing Conditions, Deconstruction Sequences, Construction Sequences, and Proposed Design. Data were also collected for impact analysis on the upstream and downstream riverside guard walls. The final design consisted of an upstream ported guard wall that is 1,000 ft in length and a downstream solid guard wall that is 800 ft in length. The implementation of submerged dikes in the upstream and downstream approaches improve navigation conditions significantly and are an essential part of the final design. Details are shown in Section 3.5 of this report.

  • Chipping away old concrete to preserve Montgomery Dam piers for the future

    With the Ohio River's navigation system at stake, the U.S. Army Corps of Engineers Pittsburgh District is restoring the aging Montgomery Dam piers, which are vital for supporting commercial barge traffic.

  • LRD teammate earns prestigious award

    The U.S. Army Corps of Engineers Great Lakes and Ohio River Division is pleased to honor Charles Sawyer, Ph.D., for his remarkable achievement in receiving the American Society of Civil Engineers Lifetime Achievement Award.

  • Potential Lock Operations Management Application (LOMA) Hardware Installation Sites along the Ohio River to Improve Automatic Identification System (AIS) Reception and Transmit Range

    Abstract: The purpose of this Coastal and Hydraulics Engineering technical note (CHETN) is to propose a list of candidate sites along the Ohio River for the installation of Automatic Identification System (AIS) shoreside towers within the US Army Corps of Engineers (USACE) Lock Operations Management Application (LOMA) program. The LOMA program manages a network of terrestrial (shoreside) AIS sites (Figure 1) and vessel-mounted AIS sites with receive and transmit capability. However, there are known limits to the reception and transmission areas served by existing shoreside towers (referred to as “coverage gaps”) along the Ohio River (DiJoseph et al. 2021). Parties interested in improving AIS coverage to enhance maritime domain awareness and navigational safety along the Ohio River may wish to pursue the installation of LOMA program hardware for this purpose.

  • Unlocking progress: Pittsburgh’s mega project takes shape with key contractors visiting Ohio River locking facility

    The Pittsburgh region is unlocking progress on the Ohio River by constructing a new navigation chamber to replace a smaller, aging lock that has been operating since 1936.

  • A Method for Evaluating Automatic Identification System (AIS) Coverage on Select Inland Waterways in 2020 and 2021: Upper Mississippi River, Illinois River, and Ohio River

    Abstract: The Automatic Identification System (AIS) shares vessel position information for navigational safety purposes. AIS broadcasts are received by other ships and terrestrial stations; however, in some areas there is no, or low, terrestrial station coverage to receive broadcasts. The US Army Corps of Engineers (USACE) developed an Online Travel Time Atlas (OTTA) to process AIS data and derive a transit count. This study examined OTTA output from 2020 and 2021 to identify areas of high or low AIS coverage along the Upper Mississippi, Illinois, and Ohio Rivers. Segments with a yearly average of two or more transit per day were classified as high coverage, those with less than a yearly average of two transits per day were classified as low coverage. Rivers were segmented using the USACE National Channel Framework reach boundaries. Results based on calculated vessel transits were as follows: Upper Mississippi River: 837.4 miles (98%) had high coverage, with 17.4 miles (2%) of low coverage; Illinois River: 190.5 miles (59%) had high AIS coverage, and 133 miles (41%) had low AIS coverage; Ohio River: 644 miles (66%) had high coverage, and 337 miles (34%) had low coverage. AIS coverage could be improved by raising antennae heights, installing repeater equipment, or adding towers.

  • When trees fly: Pittsburgh District delivers new fish habitats on Ohio River
