Wilson Dam is located at river mile 130.4 on the Saline River in Russell County, Kansas, approximately 10 miles north of Wilson, Kansas and 50 miles west of Salina, Kansas. Serval communities including Sylvan Grove, Lincoln, Beverly, Tescott, Culver, and Salina, all in Kansas, are downstream of Wilson Dam. The dam was authorized for flood risk management, water conservation, recreation, and fish & wildlife enhancement. Wilson Dam has reduced flood damage by more than an estimated $3.1 billion (2010 price level) from 1964 to 2010. The dam is 5,600 feet long composed of compacted rolled earthfill. The top of the dam sits approximately 152 feet above the stream bed. A controlled outlet works is used to make normal and emergency releases from the reservoir, and an uncontrolled spillway is used to provide additional release of water from the dam during major flood events.", "riskCharSummary":"USACE completed a risk assessment for Wilson Dam in September 2014 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. Based on the risk assessment the risks associated with Wilson dam are water overtopping the embankment during extreme flood events, erosion of the uncontrolled spillway during infrequent flooding events, high pore pressures leading to slope stability failure in the left abutment during extreme high pool, and internal erosion due to differential settlement near the right abutment. \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 Wilsons\u2019s storage capacity can cause the release of water through the outlet works or uncontrolled spillway to prevent overtopping and failure of dam, even if the river is at or beyond capacity. This can result in flooding at downstream areas or can worsen already existing flooding downstream due to the rivers being over capacity.", "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":"SALINE RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":450, "stateFedId":"KS00013", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":152, "submitDate":"2023-02-16T17:25:31.715Z", "surfaceArea":9040, "volume":8200000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1964, "congDist":"Congressional District 01, Kansas", "city":"SYLVAN GROVE", "county":"Russell", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "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":"CENWK", "otherNames":"Wilson Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;2;4;5", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2025-01-14T12:00:00.000Z", "dataUpdated":"2025-07-10T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"102600", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":277.5829, "tenthPercentile":236.1994, "ninetiethPercentile":310.0974 }, "id":5734030, "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/5734030?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/5734030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5734030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
