The McClellan-Kerr Arkansas River Navigation System is approximately 445 miles long, consists of 18 locks and dams, and provides nine-foot deep inland navigation from the Mississippi River to Catoosa, Oklahoma. This project will deepen the navigation channel to a minimum depth of 12 feet, thereby increasing the efficiency of the system. Deepening of the channel will be performed by a combination of techniques including altering the flow management, constructing dikes and jetties, and dredging the channel. This project also includes a significant environmental component to include creation of bottomland hardwood forests and high quality wetlands, as well as other environmental enhancements. The projected cost estimate of $185.5 million is cost-shared with the Inland Waterway Trust Fund, and is jointly managed by Little Rock and Tulsa Districts. To date, $7 million have been provided through an FY05 congressional add to complete the feasibility study and the Environmental Impact Statement, as well as to start dredging activities and construction of dikes and jetties. During FY06, dredging commenced and was completed at mile 348 in pool 15 in Oklahoma, which also included construction of a Least Tern Island with rock protection that was accomplished in conjunction with the dredging activities. Design of river structures was accomplished for pools 2, 7, and 5. Stone structures were constructed in Arkansas to improve self-scour of the river, and design of upland dredge disposal sites was also completed in Oklahoma. Mitigation activities, including aquatic and terrestrial surveys, were performed in both Oklahoma and Arkansas. A five-year project plan has been developed that includes an integrated project breakdown of activities and associated costs that has been vetted through the navigation stakeholders. This project has not been in the budget since FY05, and all funds have been exhausted resulting in no further work on the project.
Project Manager: Dan Brueggenjohann - eMail
Authorization: Section 136, Energy and Water Development Appropriations Act, fiscal year 2004 (Public Law 108-137)
Location: The McClellan-Kerr Arkansas River Navigation System consists of 18 locks and dams providing 9-foot depth inland navigation from the Mississippi River to Catoosa, Oklahoma.
Status: Authorized (Not Started)
Purpose: This project would deepen the navigation channel to a minimum depth of 12 feet throughout the navigation system. Deepening of the channel will be performed by a combination of techniques to include altering the flow management, constructing dikes and jetties and dredging the channel. This project also includes a significant environmental component to include creation of bottom land hardwood forests and high quality wetlands, as well as other environmental enhancements.
Issues and Other Information: Not included in the fiscal year 2009, 2010, 2011 or 2012 budgets. Additional funding in the amount $40 million could be used to continue dredging, mitigation, and construction channel training structures to develop a 12-foot minimum depth channel. The fiscal year 2012 activities are scheduled in $10 million increments; the first $10 million will continue dredging, construction and mitigation in Pools 2 and 13, the second $10 million will complete work in Pool 2 and continue work in Pool 13 to include real estate activities to support future dredging activities. The funds will also initiate dredging, construction and mitigation in Pools 7, 14, and 15, the third $10 million increment will continue work in Pools 7, 14 and 15, the fourth $10 million increment will complete Pools 7, continue work in Pool 15 and initiate work in Pools 5, 16, 17, and 18.
History of Construction: During fiscal year 2006 dredging commenced and was completed at mile 348 in Pool 15 in Oklahoma as well as commencing construction of training structures in Pools 2 and 7 in Arkansas. Construction of a Least Tern Island with rock protection was also accomplished in conjunction with the dredging activities in Pool 15. Design of river structures were accomplished in Pools 2, 7 and 5 as well as mitigation activities to include aquatic and terrestrial surveys were performed in both Oklahoma and Arkansas. A five year project plan was also developed for the project. Fiscal year 2007 efforts include placing stone structures to improve self scour in Arkansas, and the continuation of design of upland dredge disposal sites and real estate efforts in Oklahoma. No activites were performed in 2009, 2010, 2011 or 2012 and nothing is planned in 2013. Funds have been exhausted resulting in no further work ongoing on the deepening project.
