Corps of Engineers (USACE) completed construction of Denison Dam in 1944 with the primary purpose to reduce flooding in downstream communities. Denison Dam forms a reservoir called Lake Texoma Additional purposes included regulation of flows on the Red River, water supply, hydropower, recreation, navigation, and other beneficial uses including fish & wildlife. Denison Dam is located on the Red River, on the border of Texas and Oklahoma, approximately 5 miles northwest of Denison, Texas. During large storm events, the dam holds back excess water to reduce flooding downstream. After the storm passes and the Red River level recedes, the water can be safety released into the river. Water storage and releases are managed by a conduit structure through the embankment. During larger floods, water is released over the ungated spillway. The project also includes a hydroelectric power plant that began operating in 1946 that generates power for the community. Associated with the dam are also Cumberland Levees and Platter Dike. Cumberland Levees are located approximately 17 miles upstream of the dam along the Washita River. Platter Dike is located approximately 5 miles North-Northeast of the dam and closes off a low lying area near Platter, Oklahoma.", "riskCharSummary":"USACE completed a risk assessment of Denison Dam in 2012 and classified the risk associated with a potential dam breach as moderate. Large populations living downstream of the dam contribute to the risk. There is also risk associated with flooding downstream due to water flowing over the ungated spillway as part of normal operation during a large and widespread rainfall event. Life loss and economic impacts for this scenario would still be possible, although the impacts would be less than if the dam were to breach. The largest impacts for dam failure or large release would be to the cities of Denison, TX, Fulton, AR; Shreveport, Bossier City, Natchitoches, Pineville, and Alexandria, LA. Bridges crossing the Red River and key infrastructure along the river from Denison, TX to Alexandria, LA could also be damaged or destroyed.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk that Denison Dam poses to the community. A detailed risk assessment began in 2020 to further evaluate the project risk and determine if any remedial measures are warranted. Additional activities that USACE conducts on a day to day basis include 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":"RED RIVER", "separateStructuresCount":2, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":2000, "stateFedId":"OK10317", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":165, "submitDate":"2023-02-16T17:25:39.059Z", "surfaceArea":86910, "volume":18800000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1944, "congDist":"Congressional District 02, Oklahoma", "city":"HENDRIX", "county":"Bryan", "aiannh":"Chickasaw OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Lake-Texoma/", "coreTypeIds":"3", "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1", "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Lake Texoma", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;6;8", "dsacId":3, "femaRegion":"6", "lastEapExcerDate":"2024-08-24T12:00:00.000Z", "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":"111302", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6 }, "id":2063051, "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/2063051?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/2063051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/2063051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
