Bayou Bodcau Dam in 1949 and continues to own, operate, and maintain the facility today. Located in Bossier Parish, Louisiana\u2014approximately 18 miles northeast of Bossier City\u2014the dam helps control flooding along Bayou Bodcau and the Red River Basin. Bayou Bodcau Dam is a dry detention dam, which means that under normal conditions, there is little to no water impounded behind it. Water is temporarily stored during significant rainfall events and slowly released to reduce downstream flood risk.\n\nThe earthen dam is approximately 8,850 feet long with a maximum height of 76 feet and includes a 3,000-foot-long auxiliary dike, outlet works with twin conduits, and an uncontrolled spillway designed to pass large floods safely. The spillway is over 4,000 feet wide and can discharge more than 180,000 cubic feet per second when activated, which would fill up an Olympic sized swimming pool in 0.6 seconds. Although the dam does not have a year-round conservation pool or designated recreation area, it plays a critical role in reducing flood risk for downstream communities, including Bossier City, Red Chute, and areas adjacent to Bayou Bodcau.\n\nBayou Bodcau Dam\u2019s outlet works consist of two open conduits and a stilling basin that reduces the energy of water released during flood operations. The dam was built without modern filter protections such as chimney or blanket drains, and seepage control is provided only by a cutoff trench installed in the valley portion of the embankment. Although it has a history of numerous, yet minor, embankment slides and seepage concerns, the dam has continued to perform as designed since construction.", "riskCharSummary":"While Bayou Bodcau Dam greatly reduces flood risks downstream, it does not eliminate these risks. Flooding can still occur even if Bayou Bodcau Dam operates as designed. Unlikely but possible storm scenarios exist that could cause more rainfall than Bayou Bodcau Dam can safely store. To pass such a large amount of water, the dam\u2019s auxiliary spillway may activate to pass extreme flow events to keep Bayou Bodcau Dam from overtopping and breaking. If the auxiliary spillway were to activate due to a major storm, the Red Chute Levee would overtop and as much as two to six feet of water could potentially flood as far west as Bossier City. While weather can be unpredictable, spillway events can often be forecasted one-to-two days before flooding begins to impact communities. USACE is in routine communication with the National Weather Service (NWS) and the State of Louisiana Governor\u2019s Office of Homeland Security and Emergency Preparedness (GOHSEP) to ensure the proper precautions are taken.\n\nIn 2021, Bayou Bodcau Dam was assessed for any concerns that might cause the dam to fail during rare events. USACE has classified the risks of failure associated with Bayou Bodcau Dam as very low. The dam is well-built and has performed as designed since its construction in 1949. No historical storm events to date have initiated the use of the auxiliary spillway; however, in the unlikely event that a large storm event did initiate the spillway, Bayou Bodcau could rise and cause downstream flooding. Increased reservoir levels could also increase the potential for water to seep through and erode the earthen embankment at its southern abutment where the dam meets the existing natural high ground. \n\nIf Bayou Bodcau Dam breached or failed, flood waters would be deep and swift enough to damage and destroy houses, buildings, roads, bridges, and power and water supplies and even cause loss of life. The impacts of the dam\u2019s failure would be extensive throughout Bossier City, LA and as far downstream as Coushatta, LA. If the dam were to fail, as much as 6 to 15 feet of water would flood Bossier City. Interstates I-20 and I-220 would potentially be flooded and inaccessible within the city limits. U.S. Hwy 71 would also be under water extending as far south as the southern boundary of Bossier Parish. Flooding depths of 2 to 6 feet could potentially extend as far south as Loggy Bayou. The communities of Red Chute, Bossier City, Ferguson, Blenheim, Curtis, and Coushatta, LA would be impacted by flooding if Bayou Bodcau Dam were to fail. The flooded area would be much greater in size than what was impacted by the 2016 spring flood in northern Louisiana. In the unlikely event that Bayou Bodcau Dam breaches, follow all directions from emergency officials, including evacuation orders. Failure to do so puts you and your family\u2019s lives at risk. To prepare your family against possible flooding, please visit the National Inventory of Dams (NID) website to see maps showing the potential extent of flooding locations if Bayou Bodcau Dam were to breach.", "riskManagementMeasures":"To ensure Bayou Bodcau Dam continues to minimize flood risks while balancing all its project functions, USACE uses the latest rainfall forecasts and stream gauge information. USACE also regularly inspects the dam and routinely reassesses its risks.\n\nTo address risks identified in a recent assessment, USACE has performed a seepage study at the dam and has armored parts of the dam with heavy stone to prevent erosion during spillway activation.\n\nUSACE coordinates closely with the National Weather Service (NWS), the U.S. Geologic Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), and the State of Louisiana Governor\u2019s Office of Homeland Security and Emergency Preparedness (GOHSEP) concerning conditions both upstream and downstream of the dam. USACE continues to work with these agencies to prepare and practice for emergency response efforts related to Bayou Bodcau Dam. Close coordination with local and state emergency management officials allows agency personnel to act in a timely manner during an emergency.\n\nDuring high-water events, USACE dam safety professionals increase surveillance of the dam to 24 hours a day and are prepared to act if an issue occurs. USACE personnel also monitor river conditions to help optimize the dam\u2019s operations.", "riverName":"BAYOU BODCAU", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":4000, "stateFedId":"LA00179", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":76, "submitDate":"2023-10-20T13:18:56.448Z", "surfaceArea":1, "volume":2333600, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1949, "congDist":"Congressional District 04, Louisiana", "city":"BOSSIER CITY", "county":"Bossier", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/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":"3", "nonFederalDamOnFederalId":0, "designerNames":"CEMVK", "otherNames":"Bayou Bodcau Reservoir", "ownerNames":"USACE - Vicksburg District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":5, "femaRegion":"6", "lastEapExcerDate":"2020-09-10T12:00:00.000Z", "dataUpdated":"2025-07-01T12:00:00.000Z", "usaceDistrict":"Vicksburg District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"111402", "doi_region":null, "doi_region_name":"Mississippi Basin", "doi_region_number":4 }, "id":11134013, "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/11134013?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/11134013?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/11134013?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
