  • 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.

  • Hydropower offers stability during heat waves

    Hydropower dams do not produce emissions like fossil-fuel burning resources, making the Northwest’s power system the cleanest in the nation. Dams can also ramp up and down within minutes or seconds, making them very nimble and flexible during heat waves and cold snaps.

  • USACE signs Project Partnership Agreement for Caño Martín Peña Ecosystem Restoration Project in San Juan, Puerto Rico

(July 26, 2022) – The U.S. Army Corps of Engineers Jacksonville District hosted a Ceremonial Signing for the Project Partnership Agreement (PPA) and Memorandum of Agreement (MOA) to start construction of the Caño Martín Peña Ecosystem Restoration Project today at the Area Recreativa Jose Pepe Diaz (Pepe Díaz Trail Park), San Juan, Puerto Rico.

  • USACE announces planned fall release from Rathbun Lake on Chariton watershed

    The public is invited to comment on the Rathbun Lake fall release as permitted in the revised 2016 Rathbun Lake Water Control Manual. The fall release will occur likely between the last week of September through early October 2022. The release of water will not exceed 2,700 cubic feet per second from Rathbun Reservoir and would be on-going for no longer than three or four days, excluding the ramp up and ramp down.

  • Coordinated action critical to preventing flooding in Portland, Vancouver

    PORTLAND, Ore. – Coordinated operations of storage reservoirs across the Columbia Basin reduced water levels by nine feet near Portland and Vancouver in mid-June preventing additional flood damage attributable to a powerful atmospheric river that impacted most of the four-state region, and beyond.
