Corps of Engineers (USACE) completed construction of Eufaula Dam in 1964 with the primary purpose of reducing flooding downstream. The dam also provides hydroelectric power, water supply, navigation, recreation, sediment control, and fish and wildlife benefits. Eufaula Dam is located on the Canadian River, approximately 12 miles east of the town of Eufaula, OK and 31 miles south of Muskogee, OK. During large storm events, the dam holds back excess water to reduce flooding downstream. Water storage and releases are managed by a large gated spillway. The dam also consists of an earthen embankment. The project includes a hydroelectric power plant that began operating in 1964 and generates power for the communities of Okmulgee, Haskell, McIntosh, and Pittsburg Counties Oklahoma State Highway 71 runs across the top of the dam.", "riskCharSummary":"USACE completed a risk assessment in 2017 and classified the risk associated with Eufaula Dam as low. Although extremely unlikely, the primary risks to the integrity of the dam are the potential for: (1) water overflowing the embankment leading to erosion and breach, and (2) the concrete dam section becoming unstable leading to breach. In the remote event of a dam failure, the most immediate impacted areas with the major population center would be the cities of Whitefield, Webbers Falls, and Moffett in Oklahoma, as well as Ft. Smith and Van Buren in Arkansas. Failure of the dam would result in widespread flooding in these areas resulting in loss of life and damage to infrastructure along the river.\nA more likely flooding scenario includes a large release through the gated spillway during a flood with the project operating as intended. \n\nAlthough the inundation would not be as great as a breach of the dam, this scenario could still result in widespread economic impacts and loss of life due to the extent of the flooding possible as part of normal operation of the dam.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk Eufaula Dam poses to the surrounding communities. This includes conducting emergency exercises with local and state emergency responders to enhance evacuation planning, routine updates to the EAP to improve emergency response actions, and development of a detailed communication plan for the project. Additionally, the dam is well maintained through continuous operations and maintenance activities and USACE conducts detailed inspections of the project during both normal lake levels and during flood events to ensure the integrity of the structure. Lastly, the dam has an instrumentation and monitoring program to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"CANADIAN RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":520, "stateFedId":"OK10308", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":114, "submitDate":"2023-02-16T17:25:21.885Z", "surfaceArea":143000, "volume":3850600, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1964, "congDist":"Congressional District 02, Oklahoma", "city":"WHITEFIELD", "county":"Haskell", "aiannh":"Choctaw OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Eufaula-Lake/", "coreTypeIds":"3", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CESWT", "otherNames":"Eufaula Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;6;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-05-02T12:00:00.000Z", "dataUpdated":"2025-07-15T12:00:00.000Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110902", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":2874.9708, "tenthPercentile":2611.669, "ninetiethPercentile":3148.8669 }, "id":1882051, "links":[ { "type":"application/json", "rel":"root", "title":"The landing page of this server as JSON", "href":"https://api.wwdh.internetofwater.app?f=json" }, { "type":"text/html", "rel":"root", "title":"The landing page of this server as HTML", "href":"https://api.wwdh.internetofwater.app?f=html" }, { "rel":"self", "type":"application/geo+json", "title":"This document as JSON", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1882051?f=json" }, { "rel":"alternate", "type":"application/ld+json", "title":"This document as RDF (JSON-LD)", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1882051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1882051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
