"privateDamId":null, "projectDescription":"The United States Army Corps of Engineers completed construction of Hugo Dam in 1974 with the primary purpose to reduce flooding in downstream communities. Hugo Dam is located on the Kiamichi River, immediately northeast of the town of Sawyer, OK, approximately 7 miles east of Hugo, OK, and 30 miles north of Paris, TX. During large storm events, the dam holds back excess water to reduce flooding downstream. After the storm passes and the Kiamichi River level recedes, the water can be safety released into the river. Water storage and releases are managed by a gated concrete spillway. In addition to reducing flooding, the water held back by the dam forms a reservoir providing recreation benefits. Hugo Dam is also used for water supply and quality purposes along with fish and wildlife conservation.", "riskCharSummary":"USACE completed a risk assessment in 2016 and classified the risk associated with Hugo Dam as low. The risk is primarily driven by the potential for water to seep through fractures and voids within the rock foundation resulting in erosion of the overlying embankment, as well as the potential for water to seep through the embankment resulting in erosion and breach. Another potential identified is for water to seep through the foundation soil resulting in erosion of the foundation although this was found to be a lesser risk. Failure of the dam would include flooding downstream resulting in loss of life and economic impacts. In the remote event of a dam failure the largest impacts would be to the cities of Sawyer, OK, Fulton, AR, and Garland City, AR.\nA more likely flooding scenario includes a large release through the gated spillway during a flood with the project operating as intended. Although the inundation would not be as great as a breach of the dam this scenario could still result in widespread economic impacts and loss of life due to the extent of the flooding.", "riskManagementMeasures":"There are numerous activities that USACE conducts on a day to day basis to help manage risk. This includes conducting emergency exercises with local and state emergency responders to enhance evacuation planning, routine updates to the Emergency Action Plan to improve emergency response actions, and development of a detailed communication plan for the dam. Additionally, the dam is well maintained through continuous operations and maintenance activities and USACE conducts detailed inspections of the dam during both normal lake levels and during flood events to ensure the integrity of the structure. Lastly, the dam has a robust instrumentation and monitoring system to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"KIAMICHI RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":300, "stateFedId":"OK10300", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":101, "submitDate":"2023-02-16T17:25:42.226Z", "surfaceArea":13144, "volume":2655000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1974, "congDist":"Congressional District 02, Oklahoma", "city":"SAWYER", "county":"Choctaw", "aiannh":"Choctaw OTSA", "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Oklahoma/Hugo-Lake/", "coreTypeIds":"3", "damTypeIds":"9;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":"CESWT", "otherNames":"Hugo Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-02-18T12:00:00.000Z", "dataUpdated":"2025-07-15T12:00:00.000Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"111401", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":259.2018, "tenthPercentile":193.7445, "ninetiethPercentile":291.958 }, "id":1868051, "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/1868051?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/1868051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1868051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
