"politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers built the Salamonie Dam in 1966 across the Salamonie River near the town of Lagro, Indiana as one of 3 dams to reduce the risk of downstream flooding on the northern portion of the Wabash River. The water held back by the dam forms a reservoir called Salamonie Lake. USACE Chicago District operates and maintains the dam. The reservoir stores snow melt and rainfall runoff from late winter through early summer. Periodic releases of water from the reservoir occur throughout the year to maintain seasonally specified pool levels. Additionally, the reservoir provides recreational opportunities both in the lake and downstream. The dam structure is primarily an earthen embankment structure approximately 6,100 feet long and 133 feet high at the tallest point. Normal discharges from the dam are through a 16-foot diameter conduit near the center of the dam controlled by 3 large steel gates. If the reservoir levels rise above elevation 793 NGVD, flow will begin to go through an unlined, uncontrolled auxiliary spillway to the east of the dam. The spillway is approximately 575 feet wide and is crossed by 2 county roads. Water from the spillway would be directed into the Wabash River approximately 2.5 miles upstream of the confluence of the Salamonie and Wabash Rivers. In the dam's more than 50-year history, there have been no significant releases from the spillway. The pool of record at the dam occurred in June 2015 and the dam performed as designed without any problems. During this event, the reservoir level reached the sill elevation of the spillway with very little water flowing over. The dam has reduced downstream flood damage by more than an estimated $531 million since it went into operation. Upstream of the dam is a saddle dam at Lancaster, Indiana, to protect an area that would have been flooded by the reservoir during the dam's construction.", "riskCharSummary":"The Salamonie Dam reduces the risk of flooding to downstream communities, however, the dam does not eliminate the risk of flooding. Downstream of the dam are the Cities of Lagro, Wabash, Peru, Logansport, Delphi, Lafayette, and Terra Haute, Indiana along with numerous other small towns and communities along the Wabash River all the way to the Ohio River. The most likely scenario that could result in downstream flooding from Salamonie Dam would be a high-volume release of water from the dam's spillway during significant storm events. When the water level in the reservoir gets above the spillway sill, water is released to maintain the structural integrity of the dam. The spillway bypasses flow away from the lower Salamonie River to discharge into the Wabash River upstream of the confluence of the 2 rivers. Numerous local roads, such as County Road 100 S (East Salamonie Dam Road), E 50 S, and East Division Road could become impassable if water flows through the spillway. The design of the spillway is to release less than or no more than equal to the amount of water coming into the reservoir. Large releases from the spillway could create conditions similar to how the Wabash River might behave if the dam did not exist. In addition, as the reservoir level increases, flooding will also be occurring upstream of the dam as the pool will enlarge and extend nearly to the town of Warren, Indiana, about 15 miles to the southeast of the dam. This upstream flooding would likely impact several roads in between, including State Route 105, State Route 124, and State Route 9 (South Marion Road).\n\nA very unlikely, but far more devasting scenario that would produce significant flooding would be an extreme rainfall event resulting in water flowing over the earthen dam, eroding the dam and leading to a breach. If such an event occurs, an uncontrolled surge of water would flow out of the reservoir and flood downstream communities. Lagro, IN is the closest community below the dam that would be in immediate danger of large damaging flood conditions, followed by Wabash, Peru, and Logansport. The floodwaters would be swift and deep, overtopping levees, and destroying buildings and key infrastructure. Those caught unaware and unable to evacuate could perish. Other towns and cities along the Wabash River down to the Ohio River would also be impacted.", "riskManagementMeasures":"USACE is taking several steps to reduce the risk to the public. USACE staff are continuously on-site to operate and maintain the dam. USACE works closely with state and local emergency managers, regularly conducts emergency exercises, and routinely updates the emergency action plan (EAP) for the dam. USACE also conducts rigorous inspection, monitoring, and surveillance of the dam, especially during high water events. USACE also closely follows rainfall forecasts to determine when high water events may occur and provide information for any necessary flood warnings. USACE continues to work with local communities to help them understand how they can better prepare for a flood.", "riverName":"SALAMONIE RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":0, "stateFedId":"IN03005", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":20, "submitDate":"2023-10-30T19:04:34.912Z", "surfaceArea":2860, "volume":2069400, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1966, "congDist":"Congressional District 02, Indiana", "city":"LAGRO", "county":"Wabash", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":null, "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"CELRL", "otherNames":null, "ownerNames":"USACE - Chicago District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9", "dsacId":4, "femaRegion":"5", "lastEapExcerDate":"2024-01-17T12:00:00.000Z", "dataUpdated":"2025-04-17T12:00:00.000Z", "usaceDistrict":"Chicago District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"051201", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3, "thirtyYearAverage":53.3149, "tenthPercentile":31.5514, "ninetiethPercentile":82.4168 }, "id":1171109, "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/1171109?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/1171109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1171109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
