1973 with the purpose of Navigation. The dam also provides, hydroelectric power, recreation, and fish and wildlife benefits. Webbers Falls Lock & Dam is located in eastern part of Oklahoma on the Arkansas River, about 5 miles northwest of the City of Webbers Falls in Muskogee County. Webbers Falls Lock & Dam is comprised of a navigation lock chamber that maintains river levels and passes barges and boats up and down the river. The project also includes an earthen fill embankment, a gated spillway, and a powerhouse that began operating in 1973 to generate power for the Muskogee County.", "riskCharSummary":"USACE completed a risk assessment of Webbers Falls in 2022 and classified the risk as moderate. The risk is primarily driven by the potential for the spillway gates to fail due to debris impact or a barge strike. Failure would lead to loss of navigation pool and inability to pass barge traffic. A large increase in downstream flooding would not be expected if the dam were to fail as the dam is not designed or operated to reduce downstream flooding, but instead for navigation purposes. Widespread flooding could occur downstream as part of normal operation of the dam (when the gates are fully opened during a large flood). The most immediate flooding impacts would be to the towns of Webbers Falls and Gore.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk Webbers Falls Lock and Dam poses to the community. USACE is performing rehabilitation and painting of the deteriorated gates. A Major Rehabilitation Evaluation (MRE) Study is also planned for the project. The objective of the MRE is to evaluate the risk and reliability of the structure, as well as evaluating the economic benefits of several alternatives, including routine maintenance, major rehabilitation, or complete replacement of assets within the project. \n\nOther actions to reduce the risk include 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 dam. Additionally, the dam is well maintained through continuous operations and maintenance activities and USACE conducts detailed inspections of the dam during both normal reservoir 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":"ARKANSAS RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":600, "stateFedId":"OK10304", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":84, "submitDate":"2023-02-16T17:25:34.049Z", "surfaceArea":11640, "volume":2094000, "widthOfLocks":110, "secondaryWidthOfLocks":null, "yearCompleted":1970, "congDist":"Congressional District 02, Oklahoma", "city":"WEBBERS FALLS", "county":"Muskogee", "aiannh":"Cherokee OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Webbers-Falls-Lock-and-Dam/", "coreTypeIds":"3", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Lock and Dam 16", "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CESWT", "otherNames":"Webbers Falls Lock and Dam", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":3, "purposeIds":"3;6", "dsacId":3, "femaRegion":"6", "lastEapExcerDate":"2024-10-03T12:00:00.000Z", "dataUpdated":"2025-07-15T14:46:42.846Z", "usaceDistrict":"Tulsa District", "noConsequencesId":1, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":2, "damStatusId":2, "huc06":"111101", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6 }, "id":3559051, "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/3559051?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/3559051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/3559051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
