confluence with the Republican River at Junction City, Kansas. It is 19 miles west and 16 miles south of Salina, Kansas. The authorized project purposes include flood control, silt control, irrigation, water supply, low flow supplementation, recreation, and fish and wildlife. The dam consists of an earthen embankment, gated outlet works with an uncontrolled overflow notch, and an uncontrolled spillway.", "riskCharSummary":"Risk of a breach of Kanopolis Dam is understood to be above levels tolerable by society. Kanopolis Dam\u2019s greatest life safety risk is due to potential overtopping breach of the earthen dam in an extremely large flood event. Other potential failure modes include erosion due to leakage through the dam and failure of the downstream seepage collection system which could lead to erosion of the dam\u2019s foundation. Life loss consequences would be very high (100 to 1,000 fatalities) for a dam breach during an extreme flood event with affected areas extending along the Smoky Hill River past Salina, KS and along the Kansas River to Kansas City and beyond.", "riskManagementMeasures":"USACE is currently pursuing a more detailed risk assessment to further evaluate the risk of dam breach. While further study is being pursued to better understand the risk, routine monitoring and surveillance, instrumentation readings evaluate the performance of the structure. USACE periodically hosts tabletop exercises with local emergency management agencies to improve understanding of risks and improve response in case of a dam emergency. Stockpiles of emergency supplies are kept on site. Additionally, USACE will update documents detailing the required monitoring of the dam and actions planned in case of emergency. Additional risk communication efforts will be pursued.", "riverName":"SMOKY HILL RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":500, "stateFedId":"KS00005", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":131, "submitDate":"2023-02-16T17:25:41.830Z", "surfaceArea":3815, "volume":15171000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1948, "congDist":"Congressional District 01, Kansas", "city":"MARQUETTE", "county":"Ellsworth", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"3", "nonFederalDamOnFederalId":0, "designerNames":"CENWK", "otherNames":"Kanopolis Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":3, "femaRegion":"7", "lastEapExcerDate":"2025-01-14T12:00:00.000Z", "dataUpdated":"2025-05-13T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"102600", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":68.775, "tenthPercentile":58.8016, "ninetiethPercentile":82.6021 }, "id":5558030, "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/5558030?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/5558030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5558030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
