"privateDamId":null, "projectDescription":"The United States Army Corps of Engineers completed construction of Oologah Dam in 1969 with the primary purpose to reduce flooding in downstream communities. Oologah Dam is located on the Verdigris River about 8 miles northwest of Tulsa. During large storm events, the dam holds back excess water to reduce flooding downstream. This stored water can then be released in a more controlled manner to reduce dangerous flooding downstream. These releases are regulated by a discharge conduit through the earthen dam and a concrete gated spillway, located east of the earthen dam. Oologah Dam helps to regulate flows along the Verdigris River which benefits navigation along the Arkansas River and the Port of Catoosa.", "riskCharSummary":"USACE completed a risk assessment in 2024 and classified the risk associated with Oologah Dam as low. The primary risk identified is the potential for water to seep through the embankment near the outlet conduits to lead to erosion and breach. Failure of the dam would include catastrophic flooding downstream and widespread economic impacts and significant loss of life. In the remote event of a dam failure, the largest impacts would be to the cities of Claremore, Collinsville, Owasso, Verdigris, Tulsa, Jenks (including those areas behind the Jenks Levee System), and other communities along the Arkansas River. Bridges crossing the Verdigris River and key infrastructure along the river from Oologah to Webbers Falls could also be damaged or destroyed, including operation and access of the Kerr-McClellan Navigational System.\n\nThere are also operational risks associated with planned gate releases during a flood event at Oologah Dam. While flooding would be less than a breach scenario, life loss and significant economic impacts could still occur due to the possible extent of flooding.", "riskManagementMeasures":"There are numerous activities that USACE conducts on a day to day basis to help manage the risk that Oologah Dam poses to downstream communities. This includes conducting emergency exercises with local and state emergency responders to enhance evacuation planning, yearly updates to the Emergency Action Plan to improve emergency response actions, and development of a detailed communication plan for the dam. 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":"VERDIGRIS RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":280, "stateFedId":"OK10310", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":137, "submitDate":"2023-02-16T17:25:30.136Z", "surfaceArea":31040, "volume":5900000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1963, "congDist":"Congressional District 02, Oklahoma", "city":"CATOOSA", "county":"Rogers", "aiannh":"Cherokee OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Oologah-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", "nonFederalDamOnFederalId":0, "designerNames":"CESWT", "otherNames":"Oologah Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2024-06-11T12:00:00.000Z", "dataUpdated":"2025-07-15T18:50:08.728Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110701", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":751.9003, "tenthPercentile":611.7716, "ninetiethPercentile":936.4837 }, "id":5368051, "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/5368051?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/5368051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5368051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
