Engineers (USACE) constructed Stockton Dam, completing in 1969. Stockton Dam is located at river mile 49.5 on the Sac River in Cedar County, Missouri, about two miles east of the town of Stockton. Downstream of the dam are Roscoe, MO and Osceola, MO. The dam was authorized for flood control, hydroelectric power, fish & wildlife enhancement, recreation, water quality, and water supply. Stockton Dam has reduced flood damage by more than an estimated $442 million (2024 price level) from 1970 to 2021. Average annual water supply benefit is approximately $26 million. The dam is 5,600 feet long composed of compacted earth and rock fill embankment. Between the left abutment and the spillway is a 106-feet-wide concrete powerhouse. The spillway consists of a 184-feet-wide concrete ogee crest with four Tainter gates to control releases of water alongside the powerhouse. Additionally, two rim dike structures complete the reservoir rim.", "riskCharSummary":"USACE completed a risk assessment for Stockton Dam in March 2022 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. Risks include internal erosion of embankment materials during rare flood events. USACE is confident the foundation was thoroughly prepared, and the dam was correctly built and will continue to be well maintained to reduce the flood risk to downstream communities. \n\nUSACE 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 Stockton Lake storage capacity require USACE to release water through spillway gates, even if the river is at or beyond capacity, to prevent overtopping and failure of the dam. This can result in flooding at downstream areas. If an even more extreme flood event occurs, inflows into the reservoir may exceed the storage and release capacity of the dam, and overtopping may occur. If overtopping occurs the earthen embankment portion of dam could erode leading to a sudden release of water downstream. This could result in deadly flooding in Caplinger Mills, Missouri, Osceola, MO and all along Harry S. Truman Reservoir.", "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":"SAC RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":184, "stateFedId":"MO30200", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":151, "submitDate":"2023-02-16T17:25:15.858Z", "surfaceArea":24900, "volume":9887000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1969, "congDist":"Congressional District 04, Missouri", "city":"CAPLINGER MILLS", "county":"Cedar", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"5;8;9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"2", "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Stockton Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;2;3;4;5;6;8", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2025-01-29T12:00:00.000Z", "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":"102901", "doi_region":null, "doi_region_name":"Mississippi Basin", "doi_region_number":4, "thirtyYearAverage":1143.5458, "tenthPercentile":989.9895, "ninetiethPercentile":1208.6999 }, "id":5706030, "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/5706030?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/5706030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5706030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
