completed construction of El Dorado Dam in 1981 with the primary purpose to reduce flooding in downstream communities as well as water quality, water supply, fish and wildlife, and recreation. El Dorado Dam is located on the Walnut River in southeastern Kansas in Butler County on the northeast edge of El Dorado, Kansas. The dam consists of an earth fill embankment, a gated outlet works, and an uncontrolled spillway.", "riskCharSummary":"USACE completed a risk assessment for El Dorado Dam in 2015 and classified the risk associated with the dam as low. The risk is driven primarily by the potential for water flowing through foundation rock to result in erosion of the overlying embankment. While the chance of failure occurring is remote it would result in downstream flooding, loss of life, and economic impacts. In the event of a dam failure the largest impacts would be to the towns of El Dorado and Augusta, Kansas. Levees in the cities of Augusta, Winfield, and Arkansas City would be overtopped for a breach at maximum pool. \nThere are also operational risks associated with planned releases for a flood event. There would be advanced warning for a large flood of this magnitude. Spillway releases would not overtop the levees in Augusta, Winfield, and Arkansas City but some life loss would still be likely to occur given the degree of flooding.", "riskManagementMeasures":"There are numerous activities that USACE conducts to help manage the risk that El Dorado Dam poses to downstream communities. These include 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 flood events to ensure the integrity of the structure. Lastly, the dam has a robust instrumentation and monitoring program to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"WALNUT RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":350, "stateFedId":"KS00027", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":99, "submitDate":"2023-02-16T17:25:38.480Z", "surfaceArea":8400, "volume":7400000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1981, "congDist":"Congressional District 04, Kansas", "city":"EL DORADO", "county":"Butler", "aiannh":null, "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Kansas/El-Dorado-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":"El Dorado Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2024-09-12T12:00:00.000Z", "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":"110300", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":186.9744, "tenthPercentile":160.2503, "ninetiethPercentile":202.6308 }, "id":3210051, "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/3210051?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/3210051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/3210051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
