Kanopolis Dam Project Extended to Enhance Downstream Protection; Lake Levels Rise as Gates Close

The U.S. Army Corps of Engineers, Kansas City District, has announced an extension to the major outlet channel repair project at Kanopolis Dam. The project will now include the placement of additional riprap downstream to increase erosion protection, with an expected completion date in July. This significant repair project, which addresses issues identified in a 2020 inspection, has been underway to fix erosion and other damages in the outlet channel. The initial work involved replacing existing riprap and addressing the underlying geology that contributed to erosion since the dam's completion in 1948. Although the channel work is complete, this new phase adds another layer of riprap downstream from the outlet channel to provide enhanced stability.

Tuttle Creek Update for Spring Session

MANHATTAN, Kan. – The U.S. Army Corps of Engineers, Kansas City District, announce the completion of the spring period for the Tuttle Creek Reservoir Water Injection Dredging Demonstration on April 10th 2026. The project experienced an initial delay because of a fuel tank incident, and the demonstration was later extended from a planned 10 days to 15 days due to persistent high winds and lightning.

Second pilot project for innovative Water Injection Dredging set to begin at Tuttle Creek Lake after delay

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 second demonstration period for the innovative Water Injection Dredging project at Tuttle Creek Lake following last week’s delay. The second demonstration period will take place from March 26 – April 4, 2026, providing a real-world assessment of Water Injection Dredging's effectiveness in sedimentation management within inland reservoirs. This pioneering project aims to evaluate Water Injection Dredging (WID) as a potential alternative to traditional mechanical dredging. WID technology uses a pressurized and controlled injection of water to loosen sediment from the lakebed, allowing it to be carried downstream by the natural current.
