the primary purpose to reduce flooding in downstream communities as well as water quality, water supply, fish and wildlife, and recreation. Fall River Dam is located on the Fall River about miles Northwest of Neodesha, Kansas. Fall River Dam consists of an earth fill embankment, a concrete spillway with 8 large gates, and an outlet works that is an integral part of the spillway structure. The outlet works has seven smaller gates, one low flow pipe, and water supply pipe which is not currently used.", "riskCharSummary":"USACE completed a risk assessment in February 2019 and classified the risk associated with Fall River Dam as moderate. This classification is based primarily on the potential for a very rare flood to occur that results in water flowing over the top of the dam even though the maximum release possible is being made from the spillway gates. Overtopping would ultimately result in erosion and breach of the embankment dam. There are relatively small populations living downstream of the dam that would be flooded in the event of a failure of the dam. Failure of the dam would result in flooding in Fall River, Fredonia, Neodesha, and Coffeyville KS. \nA more likely scenario for flooding includes normal operation of the Dam during a large flood which results in large releases through the spillway gates as intended. Although this would result in less flooding than dam failure, this event could still result in significant widespread flooding and result in loss of life and economic impacts.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk that Fall River Dam poses to communities. Along with routine inspections and surveys, an Interim Risk Reduction Measures Plan has been developed to address the annually updated Emergency Action Plan, identifying available equipment for emergency response, establishing emergency rock and sand stockpiles, emergency exercises, and a communication plan. \nAdditionally, there are numerous activities that USACE conducts on a day to day basis to help manage risk. 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 instrumentation and monitoring system to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"FALL RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":400, "stateFedId":"KS00003", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":94, "submitDate":"2023-02-16T17:25:38.043Z", "surfaceArea":2329, "volume":3600000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1948, "congDist":"Congressional District 04, Kansas", "city":"FALL RIVER", "county":"Greenwood", "aiannh":null, "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Kansas/Fall-River-Lake/", "coreTypeIds":"3", "damTypeIds":"9;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":"Fall River Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;8", "dsacId":3, "femaRegion":"7", "lastEapExcerDate":"2024-10-23T12:00:00.000Z", "dataUpdated":"2025-07-15T17:45:06.219Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110701", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":34.5011, "tenthPercentile":25.5998, "ninetiethPercentile":53.6118 }, "id":5272051, "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/5272051?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/5272051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5272051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
