        "projectDescription":"The construction of Mississippi River Lock and Dam 13 was completed and placed into service by the U.S. Army Corps of Engineers (USACE) in December 1938 for the purpose of navigation. Lock and Dam 13 is located on the Mississippi River near Fulton, Illinois. The project consists of a main lock chamber, an auxiliary miter gate bay, and a dam that consists of a movable gate section, a submersible earth dike spillway, and non-submersible earth dike sections. The lock chamber is used to raise or lower river traffic between the upstream and downstream pools to navigate past the dam. The lock chamber can raise or lower river traffic a maximum of 11 feet, depending on the river conditions. The dam has an overall length of 14,076 feet, and includes 1,066 feet of movable gate section, 11,180 feet of non-submersible earthen dike, and 1,830 feet of submersible earthen dike. During flood events on the Mississippi River, the dam gates are raised out of the water to produce an open river condition. Once water levels recede, the gates are lowered to maintain the 9-foot navigation channel upstream of the dam.",
        "riskCharSummary":"USACE completed a risk assessment in March 2015 and classified the risk associated with Lock and Dam 13 as low. The assessment investigated the risks to the project from a large flood event overtopping the non-submersible earthen dike causing a dam failure, failures of various lock walls, and a barge impact on the miter gates resulting in an extensive shutdown of the lock. Although unlikely, a dam failure would impact river navigation upstream of the dam only and a lock shutdown was estimated to be short enough to result in no substantial economic damages to navigation. There is no estimated life loss resulting from a failure of the dam and the flood wave produced by a dam failure would remain within the riverbanks resulting in minimal to no downstream property damages.",
        "riskManagementMeasures":"USACE works to reduce the risks posed to the community by Lock and Dam 13. USACE operations and engineering staff routinely conduct detailed inspections of the project to ensure the integrity of the lock and dam, identify new deficiencies, and monitor known deficiencies. The dam is well maintained through continuous operations and regular maintenance activities. The dam has a robust instrumentation and monitoring program that allows USACE staff to regularly monitor the dam\u2019s performance under changing river conditions. The dam\u2019s Emergency Action Plan is updated regularly, and the emergency notification charts are updated annually. This plan has been coordinated with state and local Emergency Management Agencies to help improve their dam incident response planning and preparedness responsibilities. Emergency exercises are routinely held with local and state emergency responders and stakeholders to enhance the local communities\u2019 emergency response plans.",
