"politicalPartyId":null, "privateDamId":null, "projectDescription":"The Santa Rosa Dam project is owned and operated by the Albuquerque District, U.S. Army Corps of Engineers (USACE). The project includes a dam located on the Pecos River in Guadalupe County, New Mexico, approximately seven river miles upstream of the city of Santa Rosa. Construction was completed in 1979 and primary project features include a zoned earthen embankment dam; gated outlet works to adjust operational water releases into Pecos River; and a rock-cut spillway to pass much larger, uncontrolled flow during extreme events. During flood events, the Santa Rosa Dam project can be operated for flood risk reduction on its own or in conjunction with other dams to optimize upstream and downstream flood risk reduction along the Pecos River. In addition to the project\u2019s main purpose of flood risk reduction, it is authorized for sediment retention, irrigation, and recreation benefits.", "riskCharSummary":"Although the Santa Rosa Dam project has successfully reduced flooding, it does not eliminate all flood risk caused by rain downstream of the dam or due to emergency operation of the project. During infrequent emergency operation, larger required releases through the project\u2019s gated outlet works would surpass downstream river channel capacity and flood low-lying areas along the Pecos River. Although the progression of events leading to much larger, uncontrolled flow through the spillway have never occurred, uncontrolled spillway flow could greatly surpass downstream channel capacity, flood low-lying areas along the Pecos River, and be life-threatening. Flood inundation caused by uncontrolled spillway flow could cause catastrophic downstream damages to residences and infrastructure (including levees) along the Pecos River to Fort Sumner Lake, impacting the city of Santa Rosa and surrounding communities.\n\nUSACE completed a risk assessment of the Santa Rosa Dam project in 2015. Results characterize dam breach risk as NORMAL due to the combination of tolerable level of life-risk and very low likelihood of dam breach occurring either during normal operations or as the consequence of an extreme event. However, if a dam breach were to occur, flood inundation would be life-threatening and cause catastrophic downstream damages to residences and infrastructure (including levees) along the Pecos River to Fort Sumner Lake, impacting the city of Santa Rosa and surrounding communities.", "riskManagementMeasures":"USACE strives to manage risk through application of several measures including inspections and instrument evaluations, assessments and studies, maintenance activities, and risk communication. Routine inspections and instrument evaluation are performed to monitor performance of the project. Special inspections or increased inspection frequency occurs during high pools, spillway flows, or in response to earthquakes or signs of distress. Comprehensive inspections occur annually, with more detailed inspections taking place every 5 years. Assessments occur every 10 years to compare original design and construction methods to modern standards. Maintenance is routinely performed at the project and recent activities included gate rehabilitation, repair and replacement of aging electrical and mechanical components, and routine vegetation removal. Future risk communication activities include revisions to the Emergency Action Plan (EAP) and development of a formal risk communication plan. Flood warnings to notify affected communities downstream of the project are coordinated with external entities.", "riverName":"PECOS RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":1050, "stateFedId":"NM00158", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":214, "submitDate":"2023-02-16T17:25:33.706Z", "surfaceArea":16670, "volume":0, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1979, "congDist":"Congressional District 01, New Mexico", "city":"SANTA ROSA", "county":"Guadalupe", "aiannh":null, "websiteUrl":"https://www.spa.usace.army.mil/Missions/Civil-Works/Recreation/Santa-Rosa-Lake/", "coreTypeIds":"3", "damTypeIds":"5;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Los Esteros Dam", "foundationTypeIds":"1", "nonFederalDamOnFederalId":0, "designerNames":"CESPA", "otherNames":"Santa Rosa Lake", "ownerNames":"USACE - Albuquerque District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;2;5", "dsacId":5, "femaRegion":"6", "lastEapExcerDate":"2024-02-05T12:00:00.000Z", "dataUpdated":"2025-06-17T12:00:00.000Z", "usaceDistrict":"Albuquerque District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"130600", "doi_region":"UCB", "doi_region_name":"Upper Colorado Basin", "doi_region_number":7 }, "id":261043, "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/261043?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/261043?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/261043?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
