"privateDamId":null, "projectDescription":"The United States Army Corps of Engineers (USACE) completed construction of Waurika Dam in 1977 with the primary purpose to reduce flooding in downstream communities. Waurika Dam is located on Beaver Creek, which is a tributary of the Red River 6 miles northwest of the town of Waurika, OK. During large storm events, the dam holds back excess water to reduce flooding downstream. Waurika Dam consists of an earth fill embankment, an outlet conduit running through the dam, and an ungated spillway. The project was constructed with the primary purpose to reduce flooding downstream as a well as irrigation, water supply, water quality control, recreation, and fish and wildlife. Waurika Dam provides water to the cities of Lawton, Duncan, Comanche, Walters, Temple and is the only source of water for Waurika.", "riskCharSummary":"USACE completed a risk assessment in November 2021 and classified the risk associated with Waurika Dam as low. The risk is primarily driven by 1.) the potential for water to flow over the top of the dam leading to erosion and breach, and 2.) the potential for water seeping through the foundation leading to erosion and breach. Failure of the dam would include flooding downstream, economic impacts and loss of life. In the event of failure, the most immediate impacts would be to the cities of Waurika and Ryan and then communities along the Red River down to Lake Texoma. Bridges crossing Beaver Creek and the Red River along with key infrastructure along the river from could also be damaged or destroyed.\nThere is also flood risk associated with the dam due to normal operation of the dam which could include large releases through the ungated spillway during a flood. Although flooding for this scenario would be less than a dam breach scenario, life loss and significant economic impacts could still occur depending on the extent of flooding.", "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":"BEAVER CREEK", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":300, "stateFedId":"OK22203", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":106, "submitDate":"2023-02-16T17:25:33.720Z", "surfaceArea":10100, "volume":9092600, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1977, "congDist":"Congressional District 04, Oklahoma", "city":"WAURIKA", "county":"Jefferson", "aiannh":"Kiowa-Comanche-Apache-Fort Sill Apache OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Waurika-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":"Waurika Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;2;5;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-06-26T12:00:00.000Z", "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, "thirtyYearAverage":217.045, "tenthPercentile":167.399, "ninetiethPercentile":245.3968 }, "id":1655051, "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/1655051?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/1655051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1655051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
