purpose to reduce flooding in downstream communities as well as water supply, recreation, and fish and wildlife benefits. The project consists of an earthen embankment, an outlet conduit, and an ungated spillway. The dam is located on Polecat Creek, a tributary of the Arkansas River, about 11 miles southwest of Sapulpa in Creek County, Oklahoma, and 2 miles upstream from U.S. Highway 66 between Sapulpa and Oklahoma City, Oklahoma. During large storm events the dam holds back excess water to reduce flooding downstream. After the downstream river level recedes the water can be safety released into the river. Releases are made by a drop inlet that flows into a conduit for lower lake levels and by an ungated spillway for higher lake levels and larger floods.", "riskCharSummary":"USACE completed a risk assessment in June 2016 and classified the risk associated with Heyburn Dam as low. This classification is based both on the likelihood of failure and the populations living downstream of the dam. Although extremely unlikely, the three primary risks to the integrity of the dam are: (1) A flood so large that the capacity of the dam to store water is exceeded and water flows over the top of the dam (2) Water seeping through the earthen embankment along the conduit erodes the embankment and eventually weakens the dam, and (3) A large release through the uncontrolled spillway leads to erosion and breach. Failure of the dam would include flooding downstream, economic impacts, and significant loss of life. In the remote event of a dam failure the largest impacts would be to the cities of Kellyville, Sapulpa, Jenks, Bixby, Muskogee, Fort Gibson, and other communities along the Arkansas River. \n\nA more likely scenario includes the potential for water to flow over the ungated spillway during a large flood as intended. Although this flooding would be less than a breach scenario, significant economic impacts and loss of life could occur due to the extent of flooding.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk that Heyburn Dam poses to the community. 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":"POLECAT CREEK", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":200, "stateFedId":"OK10313", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":89, "submitDate":"2023-02-16T17:25:29.309Z", "surfaceArea":880, "volume":1151400, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1950, "congDist":"Congressional District 03, Oklahoma", "city":"KELLYVILLE", "county":"Creek", "aiannh":"Creek OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Heyburn-Lake/", "coreTypeIds":"3", "damTypeIds":"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":"Heyburn Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2024-06-11T12:00:00.000Z", "dataUpdated":"2025-07-15T14:49:50.578Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"111101", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6 }, "id":5081051, "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/5081051?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/5081051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5081051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
