  • Innovative Water Injection Dredging pilot project set to begin Sept. 17 at Tuttle Creek Lake

    The Kansas City District, U.S. Army Corps of Engineers, in partnership with the Kansas Water Office, is pleased to announce the start of the first demonstration period for the innovative Water Injection Dredging project at Tuttle Creek Lake. The demonstration will take place from September 17 to 27, 2025, providing a real-world assessment of Water Injection Dredging's effectiveness for sediment management within inland reservoirs. This pioneering project aims to evaluate Water Injection Dredging (WID) and downstream discharge of sediment as a potential alternative to traditional mechanical dredging with offsite sediment disposal. WID uses a controlled injection of water, under pressure, to resuspend sediment from the reservoir bed and create a density current, allowing it to be carried downstream by gravity and the natural current.
  • Groundbreaking Water Injection Dredging pilot project shifts start date to fall 2025 for critical testing

    The Kansas City District, U.S. Army Corps of Engineers, announces the Tuttle Creek Reservoir Water Injection Dredging pilot project's initial phase will shift to fall 2025. This first-of-its-kind pilot project requires custom-built equipment. The schedule change is due to manufacturing delays for specialty pump parts, a critical component of the innovative system.
  • Public input sought on Water Injection Dredging Study and Demonstration Draft Study Report
