  • Wolf Creek Dam provides enormous flood risk management benefits

    JAMESTOWN, Ky. (Jan. 13, 2023) – When the Cumberland River Basin in southeastern Kentucky experiences storms and waters rise, Wolf Creek Dam on the Cumberland River provides enormous flood risk management benefits.

  • Corps extends public comment period for proposed Willamette Valley System 30-year plan

    The U.S. Army Corps of Engineers’ Portland District (Corps) has extended the deadline from Jan. 19 to Feb. 23 for public feedback on its proposed 30-year plan for the operation and maintenance of 13 dams and reservoirs across the Willamette River Basin.

  • Risk-Based Prioritization of Operational Condition Assessments: Methodology and Case Study Results

    Abstract: USACE operates, maintains, and manages more than $232 billion of the Nation’s water resource infrastructure. USACE uses the Operational Condition Assessment (OCA) to allocate limited resources to assess condition of this infrastructure in efforts to minimize risks associated with performance degradation. The analysis of risk associated with flood risk management (FRM) assets includes consideration of how each asset contributes to its associated FRM watershed system, understanding the consequences of the asset’s performance degradation, and a determination of the likelihood that the asset will perform as expected given the current OCA condition ratings of critical components. This research demonstrates a proof-of-concept application of a scalable methodology to model the probability of a dam performing as expected given the state of its gates and their components. The team combines this likelihood of degradation with consequences generated by the application of designed simulation experiments with hydrological models to develop a risk measure. The resulting risk scores serve as an input for a mixed-integer optimization program that outputs the optimal set of components to conduct OCAs on to minimize risk in the watershed. This report documents the results of the application of this methodology to two case studies.

  • Rock repairs to start at Tuttle Creek Dam, portions of dam closed to public

    The U.S. Army Corps of Engineers, Kansas City District has announced an upcoming construction project to repair the rock overlay on the remaining portions of the upstream side of Tuttle Creek Dam. During 2019, portions of the existing rock overlay degraded due to the extended duration of high water and wave action. The initial phase of these repairs was completed in fall and winter 2021. Work is expected to begin on or around Nov. 1, 2022, and will require closure of public access at the east and west dam parking lots and the entire upstream face of the dam. These closures include all pedestrian access and bank fishing.

  • Buckhorn, Carr Creek dams continue operating as designed, providing flood damage reduction

    The U.S. Army Corps of Engineers Louisville District continues to monitor the dams at Buckhorn Lake, Buckhorn, Kentucky, and Carr Creek Lake, Sassafras, Kentucky, following severe flooding which occurred in eastern Kentucky. The Buckhorn and Carr Creek Dams on the Middle Fork and the North Fork, respectively, of the Kentucky River are currently storing water and providing a reduction to the flooding occurring downstream. The dams are structurally sound and operating as intended.

  • Environmental Effects of Sediment Release from Dams: Conceptual Model and Literature Review for the Kansas River Basin

    PURPOSE: Passing sediment from reservoirs to downstream channels is a potential solution to aging infrastructure and reservoir storage capacity loss, which is a pressing challenge nationwide. The US Army Corps of Engineers (USACE) sediment management actions at reservoirs such as flushing may drive ecological changes that may be beneficial or detrimental to downstream ecosystems. However, these potential effects are currently not well understood or documented. An exploratory study of the potential ecological effects of releasing sediment downstream from reservoirs is presented in this technical note (TN). We focus on Tuttle Creek Reservoir in Kansas and use fish species as indicators of ecological change. A literature review of Kansas fishes was conducted and three conceptual models illustrating potential benefits or negative effects of releasing sediment downstream of Tuttle Creek Reservoir was developed. Some fish species may benefit from sediment releases, while others may be negatively affected. Further research and tools are needed to develop a greater understanding of these effects.
