John Redmond Dredging Initiative

In 2012, the state of Kansas started the planning process to conduct a large-scale dredging project to restore water supply storage at John Redmond Reservoir. This project represents the first of its kind in the nation with a non-federal entity dredging sediment from a U.S. Army Corps of Engineers reservoir for the purpose of ensuring water supply storage. The ability to store water in the reservoir is critical to maintain future supply since it is the source, through a contract with the Kansas Water Office, to 19 communities and six industrial users, including Wolf Creek Nuclear Operating Station.

The Kansas Water Office has completed a Supplemental Environmental Assessment (SEA) to the Programmatic Environmental Impact Statement (PEIS) for the Removal and Disposal of Sediment and Restoration of Water Storage at John Redmond Reservoir, Kansas. The SEA provides information and evaluated the environmental impacts of three confined disposal facilities (CDFs) not previously evaluated within the PEIS. On February 25, 2016, the Tulsa District of the U.S. Army Corps of Engineers issued a Finding of No Significant Impact (FONSI) on the SEA and the three CDFs evaluated within it. Electronic copies of the SEA and FONSI issued by the Corps of Engineers are available for review below.

The state of Kansas is moving forward with efforts to dredge John Redmond Reservoir to restore water supply lost to sedimentation. Information on the project purpose, schedule, funding, public meetings and more will be continuously added to this website. In addition, the responses to several Frequently Asked Questions (FAQs) will be added to this website.

Final Programmatic Environmental Impacts Statement (FPEIS)

John Redmond 408 Final Record of Decision - Removal & Disposal of Sediment & Restoration of Water Storage at John Redmond Reservoir, Kansas - May 2015

The Kansas Water Office has completed a Final Programmatic Environmental Impacts Statement (FPEIS) to evaluate the alternatives to restore water storage at John Redmond Reservoir, including the proposed dredging project.


John Redmond Reservoir was constructed in 1964 by the Corps with an original design life of 50 years. At construction, the reservoir had a surface area of about 9,800 acres and a water storage capacity of 82,200 acre-feet (AF). In 2007, the Kansas Biological Survey completed a bathymetric survey of the reservoir and concluded that the surface area had reduced to about 8,800 acres with a water storage capacity of 50,200 AF. Decreases in surface area and volume are attributed to sedimentation. The estimated sedimentation rate of 739 AF per year is about 80 percent more than the sedimentation rate (404 AF/year) that was originally projected for the conservation pool by the Corps at the time the reservoir was completed.

Dredging sediment from the conservation pool would restore water supply storage for the benefit of the regional water users and restore the lost aquatic habitat for the benefit of public recreation and the lake ecosystem. The process for initiating a dredging project could be lengthy. To ensure the state is prepared to implement a dredging alternative when necessary, we are taking action now to begin the process.

Current Activity

The Kansas Water Office has initiated a request to dredge John Redmond through meetings and conversations with the U.S. Army Corps of Engineers, in 2012-2013, KWO will be collecting additional data, completing the necessary environmental documentation, and conducting several stakeholder and public outreach meetings about the project. All documents developed and meetings scheduled will be posted to this website.

The two key documents the Kansas Water Office will be developing for the dredging activity include:
     Request for permission to alter/modify a Corps project (33 USC 408)
     National Environmnetal Policy Act (NEPA) - Programmatic Environmental Impact Statement

Requests for Proposals

The Kansas Water Office sought proposals for the design-dredge of John Redmond Reservoir through March 19, 2013.  The Scope of Work for this project is to provide a plan with a proposed process, schedule and estimated costs for completing engineering, acquisition of permits, construction of disposal facilities, mobilization and demobilization, dredging and land reclamation. KWO reviewed the proposals submitted and selected Great Lakes Dredge & Dock LLC (GLDD) as the successful bid team. Negotiations and award of a contract are underway. A summary of the bid proposals received is available here.

“Our office received a tremendous response from qualified and experienced dredging companies from around the nation,” said Tracy Streeter, Kansas Water Office Director. “Great Lakes Dredge & Dock Company was selected because of their work on other similar size scoped projects and their competitive costs. We are pleased to be able to move forward and work with them on this project, a first of its kind in the nation.”

Founded in 1890, GLDD is the oldest and largest provider of dredging services in the United States. The company has completed several projects in the mid-west including the removal of 2.2 million cubic yards from Lake Worth in Texas and 2.3 million cubic yards from Clear Lake in Ventura, Iowa. GLDD will be partnering with EBH and Associates who is headquartered out of Great Bend, KS for the engineering and design of the sediment disposal facilities. They will also contract with Schmidt Excavating, LLC, a general contractor based in Burlington, KS for earth moving services to construct the disposal facilities.

Frequently Asked Questions (FAQs)

         Questions Regarding the Design-Dredge for John Redmond Reservoir Request for Proposals

1.  Have any alternatives to dredging John Redmond reservoir been considered?

Many short and mid-term alternatives to reduce sedimentation at the lake or increase storage have already or are currently being implemented. Streambank restoration projects on the Neosho and Cottonwood Rivers will decrease the amount of new sediment delivered downstream to John Redmond. After many years of negotiations, a 2-foot pool raise and reallocation of storage was completed at the reservoir in 2013. This pool raise increased the storage available for water supply by approximately 20,000 AF. While these actions have been important steps to extending the life of the reservoir, removal of the already deposited sediment is necessary to ensure a reliable water supply is available to meet the current and future area demands.

Other alternatives to dredging that have been evaluated include construction of a pipeline to transfer water from other areas of the state or region and development of a new reservoir. Based on cost and feasibility, the dredging alternative has been determined to be a more viable alternative.

2.  Who is paying for this dredging activity?

Costs for dredging will be borne solely by the state or other non-federal partners and include planning, permits and studies, land acquisition, dredged materials disposal area and dewatering area construction, dredging, and disposal management.

3.  How much sediment will be removed?

The plan for this phase of dredging at John Redmond is to remove 3,000,000 cubic yards of sediment.

4.  How long will it take to dredge John Redmond?

Dredging activities associated with the dredging of 3,000,000 cubic yards of sediment from John Redmond will last from late April/early May of 2016 on through December of 2016.

5.  Where will the dredged sediment be placed?

All of the confined disposal facilities (CDFs) used for sediment disposal for this phase of dredging activities are located between the John Redmond dam and Burlington. Dredged materials will be placed in confined disposal CDFs located downstream of the John Redmond dam and south of the Neosho River.
