"privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) completed construction of Proctor Dam in January 1964 as one of four flood risk management projects in cooperation with the Brazos River Authority. It is located approximately 8 miles northeast of the town of Comanche in Comanche County, Texas. The dam reduces the risk of downstream flooding along the Leon River by holding back waters during heavy rain events. The dam is an earthen dam, approximately 2.5 miles long, with a gated concrete spillway in the middle. The gated spillway is controlled by eleven tainter gates that hold water to 9 feet below the top of the dam to regulate water storage and releases. There are also two low-flow conduits in the center of the gated spillway for water supply releases. Additional benefits of the dam are recreation and fish and wildlife conservation.", "riskCharSummary":"Although Proctor Dam reduces the risk of flooding to downstream communities, the dam does not eliminate the risk of flooding. Proctor Dam is designed to reduce the peak flooding levels downstream without risking the structural integrity of the dam. USACE completed a risk assessment in March 2019, and a modification study in April 2020, and classified the risks associated with the project as moderate. This classification is based on an extremely unlikely flood event which could cause water to flow through the dam\u2019s foundation and eventually weaken the dam. In the remote event of a dam breach, the largest impacts would be to the Cities of Belton and Temple, TX, located approximately 200 miles downstream of the dam. Downstream flooding of these Cities would occur within three days of breach, and could be as deep as a one-story structure, damaging or destroying buildings. The City of Sugarland, TX, located approximately 435 miles downstream of the dam, would also be impacted in the remote event of a dam breach. Downstream flooding in Sugarland would occur within 14 days of breach and be as deep as a one-story structure, damaging or destroying buildings and critical infrastructure such as schools, police and fire stations, and a hospital. In addition, some evacuation routes would be under water, increasing evacuation distances. The most likely scenario that could result in downstream flooding is high volume releases from Proctor Dam through the gated spillway during high water events. These surcharge operational releases occur when the reservoir's flood storage capacity is exceeded and the spillway gates are opened to allow excess water to flow through the spillway. Surcharge releases through the spillway during the largest expected flood in the watershed would put thousands of people at risk and flood waters could be as deep as a one-story building. Although the large downstream communities have well-practiced emergency action plans, and local emergency managers are aware of the unlikely potential for dam failure, breach of the dam would result in significant loss of life and severe economic damages.", "riskManagementMeasures":"To lower the risks associated with the dam, USACE conducted a Dam Safety Modification Study in April 2020 to evaluate alternatives to reduce risks. The primary alternative under consideration includes installing a filter trench collection system, to capture any water seeping through the dam and safely transport it away from the dam and increasing the thickness of the berm already installed at the toe of the dam. Once approved and funded, construction activities will begin with an estimated completion date in late 2024. USACE has also implemented a temporary change to the water control manual to make non-damaging releases from the gated spillway at lower lake elevations than previously approved to reduce the water pressure on the dam and reduce the amount of water seeping through the dam. This temporary change to the water control manual will be reevaluated once the dam modification construction is complete. Inspections and monitoring are performed regularly to ensure the health and safety of the dam. Surveillance and inspections are increased as the lake elevation rises. Routine maintenance and dam safety monitoring are performed to ensure the dam is functioning as designed. The Emergency Action Plan is updated and exercised annually, improving emergency response and coordination between USACE elements and downstream federal, state, county, city agencies, and stakeholders. USACE also communicates risks associated with Proctor Dam annually with stakeholders and Emergency Managers.", "riverName":"LEON RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":440, "stateFedId":"TX00010", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":86, "submitDate":"2023-02-24T00:00:00.000Z", "surfaceArea":4610, "volume":3060000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1964, "congDist":"Congressional District 25, Texas", "city":"GATESVILLE", "county":"Comanche", "aiannh":null, "websiteUrl":"https://www.swf-wc.usace.army.mil/proctor/", "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":"CESWF", "otherNames":null, "ownerNames":"USACE - Fort Worth District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;4;5;8", "dsacId":3, "femaRegion":"6", "lastEapExcerDate":"2024-10-10T12:00:00.000Z", "dataUpdated":"2025-06-23T18:40:42.583Z", "usaceDistrict":"Fort Worth District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"120702", "doi_region":"ART", "doi_region_name":"Arkansas-Rio Grande-Texas Gulf", "doi_region_number":6, "thirtyYearAverage":70.3767, "tenthPercentile":35.2606, "ninetiethPercentile":86.4632 }, "id":183048, "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/183048?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/183048?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/183048?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
