the primary purpose to reduce flooding in downstream communities. Broken Bow Dam is located on the Mountain Fork River, about 9 miles northeast of the town of Broken Bow, OK. During large storm events, the dam holds back excess water to reduce flooding downstream. After the storm passes and the Mountain Fork River level recedes, the water can be safety released into the river. Water storage and releases are managed by a gated spillway. The project also includes a hydroelectric power plant that began operating in 1970 that generates power for the community. In addition, the water held back by the dam forms a reservoir providing recreation benefits. Broken Bow Dam is also used for water supply purposes and fish and wildlife conservation. Associated with the dam is also a reregulation dam, located 5 miles downstream of the powerhouse, and two dikes located just north of the dam. The reregulation dam satisfies the low flow requirements of the U.S. Fish and Wildlife Service and smooths fluctuations caused by the powerhouse releases.", "riskCharSummary":"USACE completed a risk assessment in August 2017 and classified the risk associated with Broken Bow Dam as low. The risk is primarily driven by the potential for water seeping through rock fractures in the foundation beneath the dam which could lead to embankment erosion and breach. Other issues identified includes the remote potential for the same issue to occur but through the dike embankment or for water to flow over the gated spillway causing erosion that eventually downstream that weakens the spillway. Failure of the dam would include flooding downstream resulting in loss of life and economic impacts. In the remote event of a dam failure the largest impacts would be to the unincorporated community of Eagletown, OK. There is also flood risk associated with the dam due to normal operation of the dam which could include large releases through the gated spillway during a large flood.", "riskManagementMeasures":"There are numerous activities that USACE conducts on a day to day basis to help manage risk. This includes conducting emergency exercises with local and state emergency responders to enhance evacuation planning, routine updates to the Emergency Action Plan 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 lake levels and during flood events to ensure the integrity of the structure. Lastly, the dam has a robust instrumentation and monitoring system to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"MOUNTAIN FORK RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":320, "stateFedId":"OK10307", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":225, "submitDate":"2023-02-16T17:25:22.505Z", "surfaceArea":20500, "volume":5052480, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1968, "congDist":"Congressional District 02, Oklahoma", "city":"EAGLETOWN", "county":"McCurtain", "aiannh":"Choctaw OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Broken-Bow-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":"Broken Bow Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;6;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-02-12T12:00:00.000Z", "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":"111401", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":1177.8515, "tenthPercentile":1109.721, "ninetiethPercentile":1261.8743 }, "id":2202051, "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/2202051?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/2202051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/2202051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
