"privateDamId":null, "projectDescription":"The United States Army Corps of Engineers completed construction of Kaw Dam in 1976 with the primary purpose to reduce flooding in downstream communities. Kaw Dam is located between Kay County and Osage County, on the Arkansas River about 7 miles east of Ponca City, Oklahoma. During large storm events, the dam holds back excess water to reduce flooding downstream. After the storm passes and the river level recedes, the water can be safety released into the river. Water storage and releases are managed by a large gated spillway. This spillway is flanked on each side by concrete dam sections and earthen embankments. The project also includes a hydroelectric power plant operated by Oklahoma Municipal Power Authority (OMPA) that began operating in 1989 that generates power for the community. In addition to the power generated at the dam itself, the project provides water supply for the Public Service Company of Oklahoma (PSO) power plant located downstream along the Arkansas River. Kaw Dam also provides water supply, water quality control, recreation, and fish and wildlife benefits.", "riskCharSummary":"USACE completed a risk assessment in November 2014 and classified the risk associated with Kaw Dam as low. Although extremely unlikely, the three primary risks to the integrity of the dam are related to the potential for water seeping through the sandy foundation beneath the embankment dam leading to erosion and breach. Failure of the dam would include flooding downstream, economic impacts, and loss of life. In the remote event of a dam failure the largest impacts would be to the cities of Ponca City, Cleveland, Sand Springs, Tulsa, Jenks, and Bixby, and other communities along the Arkansas River. \n\nA more likely flooding scenario includes a large release through the gated spillway during a flood with the project operating as intended. Although 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.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk that Kaw 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 (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 (O&M) 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":"ARKANSAS RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":400, "stateFedId":"OK20509", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":125, "submitDate":"2023-02-16T17:25:36.287Z", "surfaceArea":16750, "volume":8560000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1976, "congDist":"Congressional District 03, Oklahoma", "city":"PONCA CITY", "county":"Osage", "aiannh":"Osage Reservation", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Kaw-Lake/", "coreTypeIds":"3", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1;13", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1;13", "formerNames":null, "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CESWT", "otherNames":"Kaw Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;6;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-01-30T12:00:00.000Z", "dataUpdated":"2025-07-15T17:57:04.525Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110600", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":532.3666, "tenthPercentile":474.9492, "ninetiethPercentile":648.9813 }, "id":5294051, "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/5294051?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/5294051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5294051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
