with the primary purpose to reduce flooding in downstream communities and water quality, as well as water supply, fish and wildlife, and recreation. Council Grove Dam is located on the Neosho River at the town of Council Grove, Kansas. Council Grove Dam consists of an earth fill embankment, a concrete gate tower outlet works, and an ungated spillway used to make releases during larger floods.", "riskCharSummary":"USACE completed a risk assessment for Council Grove Dam in 2022 and classified the risk associated with the dam as moderate. The risk is driven primarily by the potential for water to flow over the top of the dam during an extreme flood resulting erosion of the embankment and breach. \n\nFailure of the dam would include flooding downstream resulting in loss of life and economic impacts. In the event of a dam breach, the primary impacted community would be Council Grove, KS located two river milers below the dam. Other potential impact areas could include Dunlap, Americus, Emporia, Hartford, Neosho Rapids, and Hartford Kansas \n\nThere is also flood risk associated with the dam due to normal operation of the dam which could include releases through the ungated spillway during a large flood. While this flooding would be less than a breach scenario it could still result in economic impacts and potential loss of life depending on the extent of flooding.", "riskManagementMeasures":"There are numerous activities that USACE conducts to help manage the risk that Council Grove 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, 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 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":"GRAND NEOSHO RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":500, "stateFedId":"KS00001", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":105, "submitDate":"2023-02-16T17:25:30.057Z", "surfaceArea":3259, "volume":1325200, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1964, "congDist":"Congressional District 02, Kansas", "city":"COUNCIL GROVE", "county":"Morris", "aiannh":null, "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Kansas/Council-Grove-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":"Council Grove Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":3, "femaRegion":"7", "lastEapExcerDate":"2024-07-23T12:00:00.000Z", "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":"110702", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5 }, "id":1936051, "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/1936051?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/1936051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1936051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
