Engineers (USACE) constructed Blue Springs Dam in 1988. Blue Springs Dam is located on the East Fork Little Blue River about 4.7 miles upstream of the confluence of the Little Blue River and East Fork Little Blue River. The Dam is located on the eastern outskirts of the greater Kansas City Metropolitan area within Jackson County, MO. The surrounding areas are developing suburbs. Areas immediately downstream of the dam are actively being developed in or near the Little Blue River floodplain as of 2024. The lower reach of the Little Blue River, near the Missouri River, is largely rural and consists of agricultural fields. Blue Springs Dam was authorized for flood control, recreation, fish & wildlife enhancement and water quality. Blue Springs Dam has reduced flood damage by more than an estimated $71 million (2023 price level) from 1988 to 2020. The dam is a rolled earth and rockfill embankment approximately 2,500 long and has a maximum height of approximately 70 feet above the streambed.", "riskCharSummary":"Blue Springs Dam was well constructed and is well maintained. The most recent risk assessment for Blue Springs Dam was completed in 2023, which characterized the risk posed by the dam as low. Although the dam reduces the risk of flooding, it does not eliminate flooding. The most likely scenario resulting in downstream flooding from the Blue Springs Dam would be spillway discharge due to large, long, or multiple precipitation events in a relatively small duration. Although such a precipitation event leading to the use of the spillway of the dam is rare, it is a possibility. Far less likely scenarios that could lead to downstream flooding from Blue Springs Dam is embankment slope instability, internal erosion, or dam overtopping. Overtopping would take vast amounts of water as the inflow of the water from the East Fork Little Blue River and water from storms will have to be larger than the discharge from uncontrolled spillway. In these scenarios, a large surge of water would flow out of the reservoir, flooding downstream communities (Independence, MO). Some water from a potential dam breach may overtop the levee at Lake City and proceed to the east along Fire Prairie Creek before reaching the Missouri River. Some notable infrastructure impacted includes multiple senior care facilities and the MRLS 351-R Levee.", "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 reservoir levels. Rainfall forecasts and reservoir levels are routinely monitored and if a high reservoir level is forecast, 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 continue to work with communities that are developing downstream of the dam to help them understand how they can better prepare for a potential flood.", "riverName":"EAST FORK LITTLE BLUE RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":300, "stateFedId":"MO12099", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":70, "submitDate":"2023-02-16T17:25:19.902Z", "surfaceArea":722, "volume":2200000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1988, "congDist":"Congressional District 05, Missouri", "city":"Lees Summit", "county":"Jackson", "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":"CENWK", "otherNames":"Blue Springs Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;4;5", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2025-02-19T12:00:00.000Z", "dataUpdated":"2025-03-28T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"103001", "doi_region":null, "doi_region_name":"Mississippi Basin", "doi_region_number":4, "thirtyYearAverage":14.0022, "tenthPercentile":13.6206, "ninetiethPercentile":14.5757 }, "id":15200030, "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/15200030?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/15200030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/15200030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
