Federal engineers are launching the second phase of an experimental dredging operation at Tuttle Creek Reservoir to combat severe sediment buildup. The U.S. Army Corps of Engineers began water injection dredging (WID) last fall, using a specialized barge with water jets to stir up and push sediment through the dam outlet. Project manager Laura Totten announced work will run from March 17-27, requiring temporary closure of boat ramps and parking areas.

Tuttle Creek, like all Kansas reservoirs, faces a critical threat from sediment accumulation. The USACE projects that without intervention, the reservoir will be 75% full of mud by 2049 and nearly completely filled by 2074. This would severely impact flood control and water supply capabilities for surrounding communities. The experimental WID method represents a first-of-its-kind approach to extending reservoir lifespans in the state.

The USACE plans a third demonstration period in June and July, with data analysis and results expected in late 2026 or early 2027. Engineers are also testing alternative methods at other Kansas reservoirs, including hydrosuction at John Redmond Reservoir. These experimental approaches aim to address the statewide challenge of reservoir sedimentation that threatens water infrastructure across Kansas.
