Milford Dam is located on the Republican River, approximately 4 miles Northwest of Junction City, KS. Downstream of the dam is agricultural land and the major communities of Junction City, Manhattan, Topeka, Lawrence, Kansas City, Kansas, and Kansas City, Missouri. The dam was authorized for flood control, water supply, water quality, navigation, recreation, and fish & wildlife enhancement. Milford Dam has reduced flood damage by more than an estimated $1.3 billion (2010 price level) from 1967 to 2010. The dam is 6,300 feet long composed of rolled earthfill. The top of the dam sits approximately 147 feet above the stream bed. Normal releases of water pass through the outlet works near the south end of the dam. The Milford Dam project also contains a 1,250 feet wide uncontrolled spillway south of the embankment.", "riskCharSummary":"USACE is confident that the dam is solidly built, well maintained, and will continue to significantly reduce flood risks. However, the dam alone cannot eliminate all flooding. Extreme rainfall events that exceed the Milford Lake storage capacity can cause the release of water through the uncontrolled spillway to prevent overtopping and failure of the dam. This can result in flooding at downstream areas.\n\nUSACE completed a risk assessment for Milford Dam in July 2016 to determine the ability of USACE to meet the flood risk management goals of the dam. As a result, the project\u2019s risk is characterized as low. As with all earthen embankment dams, if an extreme flood event occurs, inflows into the lake may exceed the storage and release capacity of the dam, and overtopping may occur. If overtopping occurs the earthen embankment could erode leading to a sudden release of water downstream. This would result in extreme flooding in the downstream communities with the worst impacts at the communities of Junction City, KS and Manhattan, KS.", "riskManagementMeasures":"USACE will continue to work closely with state and local emergency managers, conduct emergency exercises, and incorporate any new information into our collective emergency action plans. We will continue rigorous monitoring and surveillance of the dam and will do so more frequently when heavy rainfall causes high lake levels. Rainfall forecasts and lake levels are routinely monitored and if a high lake level is forecasted, we will promptly inform local and state emergency managers so that they can take protective actions, make flood warnings, and prepare for emergency responses. We will work with communities that are developing downstream of the dam to help them understand how they can better prepare for a potential flood.", "riverName":"REPUBLICAN RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":1250, "stateFedId":"KS00008", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":126, "submitDate":"2023-02-16T17:25:20.211Z", "surfaceArea":15708, "volume":15000000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1966, "congDist":"Congressional District 02, Kansas", "city":"JUNCTION CITY", "county":"Geary", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"5;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"3", "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Milford Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;4;5;8", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2025-02-27T12:00:00.000Z", "dataUpdated":"2025-07-03T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"102500", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5 }, "id":5604030, "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/5604030?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/5604030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5604030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
